About this Manual

About this Manual - 1

About this ManualThe functional structure of this manual is a result of the

continuous increase of the CITAM functions and, consequently,of the size of this user manual. The description of the three op-eration modes is marked by one of the three icons shown inthe table “Symbols and Spelling”.

In chapter 1, General Description, you will find an overview andshort description of the device features, as well as all newly in-troduced functions, from software release 4.0 onwards.

The functionality of the CITAM plug-in version for the CITAM-Rack corresponds to the functionality of the desktop device.

With the desktop device SUPCON, up to 75 CITAMs can becentrally addressed via one terminal.

FeaturesThe CONTROLWARE ISDN TERMINAL ADAPTER

MODULE (CITAM) provides terminal equipment not supportingISDN with access to the Integrated Services Digital NetworkISDN which digitally handles all kinds of telecommunicationsrequirements of today.

The CITAM terminal adapter provides an effective link betweenthe conventional data transmission interfaces X.21, V.24 andV.35, and the ISDN interfaces S0 and S0FV. In this respect, theCITAM performs two main tasks: data rate adaptation andtranslation of dialing information.

The CITAM provides operation of two independent transparentB-channels via ISDN. To do so, the CITAM provides the termi-nal interface with the S0 interface functions and vice versa.Signaling on the terminal interface corresponds with V.25bis,X.21 and the Hayes AT standard.

It is also possible to automatically establish an ISDN connec-tion by evaluation of the Data, RTS, C or DTR interface sig-nals. The useful terminal data to be transmitted is translated tothe assigned B-channel. The terminal supports synchronousand asynchronous transmission and receipt of data for speedsbetween 300 bps and 64 kbps.

For speeds between 300 bps and 56 kbps, the CITAM providesbit-rate adaptation according to V.110 and X.30.

Operation of the CITAM corresponds with that of modemsadapting data communication interfaces to the telephone line.

Depending on the version used, the terminal adapter consistsof different modules. For the CITAM, various interface modules(MICs) are available.

Interface modules are available as 1-port and as 2-port versionas well for X.21, V.24 and V.35 each.

1 General Description / Features


The CITAM rack-mount module provides a modified CEPT in-terface and can therefore replace conventional rack-mountdial-up modems with CEPT interface. If you use a non-Control-ware module rack, please make sure the modified CEPT in-terface is compatible. If this is the case, transmission via a B-channel is provided for speeds up to 64 kbps.

The CITAM allows to save up to 8 call numbers consisting ofup to 19 numeric characters each. The call numbers as well asboth port configurations are stored in an EEPROM. Thus, it isguaranteed that this data is retained for an indefinite period oftime, even in the event of power failure.

Although the CITAM was provided with a huge variety of functions,it was aimed at keeping operation as user-friendly as possible.

The basic configuration settings are controlled via two rows of DIPswitches, with 8 switches each. The basic configuration fulfills allrequirements for operation with an interface procedure likeV.25bis, X.21, or Hayes AT; in these cases, no changes have tobe performed via the front panel or the supervisor.

The four-digit display provides you with menus, status mes-sages etc. If you wish to modify configuration options viathe front panel, use the SELECT AND ENTER keys.These changes remain effective even in the event of a powerfailure.

The keys are designated according to their usages. You alwaysuse the SELECT key in order to make a selection, e.g. in a menuselection or for the selection of different options. And you alwaysuse the ENTER key to activate, confirm or terminate your input.

Menu-driven configuration and control are also provided by anasynchronous terminal. In this respect, a window system pro-vides user-friendly operation. Additionally it is possible also toconfigure the CITAM via V.25bis or Hayes AT interface signalsto a certain extent (refer to chapter 8).

The Controlware CITAM terminal adapter is a highly sophisticatedproduct representing the current state of technology.

Basic Setting and Configuration 4

4 Basic Setting and Configuration - 1

4 Basic Setting and

Configuration4.1 DIP Switch Blocks and

Subaddress Rotary SwitchThe CITAM can be configured via two DIP switch blocks.

The settings made with the switches already suffice to operatethe CITAM with an interface procedure. Further settings arenot required.

The interface module (MIC) may only be re-moved by service personnel authorized byControlware. Noncompliance with this conditionmay lead to the loss of claims under guarantee.

If the CITAM provides two ports, the setting is valid for both ofthem after delivery or after the execution of a reset default.This means that both ports have to be controlled with thesame interface procedure, for example, if no further configura-tion changes are set for the second port via the front panel.

With the CITAM the term subaddress has the same meaningas Endgeräteauswahlziffer (EAZ).During 1TR6 operation, the EAZ can be set for port selectionwith the subaddress rotary switch.

The set subaddress is always valid for port 1. If a second port isadditionally available, its subaddress always exceeds thesubaddress of port 1 and, thus, the set address by the value 1.

Example: Set subaddress 03

Port 1: subaddress 03Port 2: subaddress 04

4 Basic Setting and Configuration


If, however, the subaddress of port 1 is as-signed 8, then the subaddress of port 2 is as-signed 1. The subaddress 0 is used for “globalcall”, i.e. all connected devices are addressed. Ifa “global call” is made, port 1 of the CITAM re-acts first. Port 2 can only be addressed with a“global call” if port 1 of the CITAM is alreadybusy.

If leased lines or PBX hunting groups are used,the subaddress rotary switch provides additionalfunctions (see section 4.2 and chapter 11).

Independent of that, all set options can be individually config-ured for every port via the operating elements on the CITAMfront panel, as mentioned above, for example for the operationof both ports with different interface procedures.

If the setting for a port was changed by means of softwareconfiguration, the DIP switch setting is no longer valid for thisport, i.e. changes at the DIP switches do no longer affect theconfiguration. To apply the DIP switch settings again, the DIPswitches have to be reactivated (see section 7.1).

All previous menu settings will be lost in thiscase.

Fig. 4-3: Subaddress rotary switch

Settings 0, 1, and 2 provide special functions: With position 0the CITAM is configured for a PBX hunting group (see chapter10).

A PBX hunting group is a bundling of several ISDN connec-tions with same call number.

By setting DIP switch S12 to “ON”, the option for selecting thetype of leased line connection is activated. The CITAM sup-ports four types of leased lines (The designations for trans-mission paths provided by the Deutsche Telekom AG aregiven in parenthesis; see table in the appendix):

Variant A: 1 B channel + 1 D channel (Digital S01)or. 2 B channels + 1 D channel (Digital S02)

Variant B: 1 B channel (Digital 64S)Variant C: 2 B channels



4.3 Call NumbersUp to 8 call numbers can be stored by the CITAM. In addi-

tion to the digits 0-9, the special characters “/” and “*” can beused.

Please note the different settings for the software version forNorth America and the CUSTOMNET software for Australia(see chapter 14).

In the case of the 1TR6 protocol, a call number consists of a“basic” call number and the EAZ (Endgeräte-Auswahlziffer). Incontrast to that, only complete call numbers are used in thecase of the DSS1, which are designated as MSN (multiple sub-scriber numbers).

4.3.1 Connection Set-UpDuring the operation according to the 1TR6 protocol, the

EAZ can be separated from the actual call number by a sepa-rator character. The characters “/” or “*” serve as a separatorcharacters.

In section 7.35 the conditions are described under which theEAZ can be automatically copied to the end of the call number.

During 1TR6 operation the EAZ 0 is interpreted by the CITAMas a “global call”. If the EAZ 0 is received, the set EAZ of theport (subaddress rotary switch resp section 7.6) is ignored. Inthis case port 2 can only be addressed with a “global call” ifport 1 is already busy.

Example: The call number is 76543 (+ EAZ),♦ With 76543*8 or 76543/ 8 the call number

76543 and the EAZ 8 are dialed.

♦ With 76543 (and the parameter de-scribed in chapter 7.25 activated) the callnumber 76543 and the EAZ 0 are dialed,which corresponds to a “global call”.Entering 76543*0 or the call number of76543/ 0 is also possible.

♦ If the parameter described in section7.35 is activated, the call number, whichis extended by the EAZ, is dialed.

4.3 Call Numbers


4.3.2 Local Call NumberThe LOCALCHECK has to be activated for both ports. The

own (“local”) call number is described as the “local number”,which is used for subaddressing and is sent by the ISDN net-work in the place of a EAZ (applies to countries in where noEAZ is supported).

With the help of the local check, the routing for incoming calls(port selecting procedure) can also be transmitted. If calls aresent, the LOCAL NUMBER is also transmitted as “calling partynumber” (DSS1) resp “origination address - OAD” (1TR6).

If LOCALCHECK is not activated when calls are sent, the de-fault number is entered by the network if this service feature isactivated.

If the parameter INBAND callback (refer to chapter 7.25) isactive the local calling number is not sent with an outgoing callif the number is stored in the table of calling numbers.

The “LOCAL NUMBER” is also stored at one of the eight stor-age locations. The evaluation is executed, starting from thelast digit of the call number in reverse order.

Set-Up: Call number without additional EAZ

Examples: (a) (0)*615112345(b) 345(c) 3?5If the call number (0)*615112345 is re-ceived, this call is accepted in all above-mentioned examples.

If the call number (0)*615111345 is re-ceived, the call is accepted in examples (b)and (c).

If the call number (0)*615111365 is received,the call is accepted in in example (c) only.

* In the EURO-ISDN the digit 0 standing at the beginning ofnumbers is not transmitted.

The “LOCAL NUMBER” consists only of a callnumber without EAZ.



4.3.3 Security Check for IncomingCall NumberTo perform a security check for an incoming call number (if

the call number is provided by the ISDN network), the callnumber is designated as “INCOMING NUMBER”.

As a security feature , the CITAM supports the incoming checkfor calling numbers. The„ INCOMING NUMBER“ can addition-ally include three special characters.

The character “?” can be used as a wild card, i.e. the digit atthis place is not checked. The character “*” is used at the endof the call number if it is intended to check the entire number.If the call number is entered without “*” its last character is notchecked. If the character “*” is used within the number, theremaining (following) digits of the call number are notchecked.

The “INCOMING NUMBER” may include several “?”, but onlyone “*”.

If the call number is not prematurely concluded with a “*”, theEAZ has to be entered and separated from the call numberwith the character “/” or “*”. The value of this EAZ is notchecked, nevertheless it has to be provided because of therequired length of the call number. Thus, the character storedlast has the same function as a “?”.

Set-Up: Call number [?] [*]If no “*” is used, the complete call num-ber has to be entered.

Example 1: 06151??2*The first five digits are checked; thenext two digits are optional. The digit “2”has to match. The rest of the number isignored.

Example 2: 061511234/5The last digit of this number is thesubaddress. An incoming call number iscompared up to and including digit “4”.The value of digit “5” (subaddress) is in-significant.

4.3 Call Numbers


The call number in example 2 has the same set-up as a callnumber for the connection set-up. Therefore, this call numbercan also be used for a connection set-up.

It has to be noted, however, that the last digit (in example 2:digit 5) constitutes the EAZ (in 1TR6) which is then called.

If the “INCOMING NUMBER”, however, con-sists of special characters, this call numbercannot be used for a connection set-up. If aspecial character is available, this number ismarked internally. If a connection set-up is nev-ertheless attempted with this number, an errormessage is sent.

If INCOMINGCHECK was activated for the option “ITel” in thesubmenu “CONF”on LAYER 4, the incoming call number iscompared with all call numbers stored on storage locations 1to 8. This means also that every remote terminal which can becalled via a stored call number can execute a call itself and isaccepted.

When selecting the options Inband ON or In-band BUS, the INCOMINGCHECK has to beactivated for both ports.



4.3.4 SPID Number for the North American and theAustralian CUSTOMNET ISDN SoftwareIn the case of these software versions it should be noted

that only the storage locations T.01 to T.06 are available forcall numbers.

Storage locations T.07 and T.08 have to be considered asspecial locations. They are reserved for the SPID numbers.These SPID numbers are assigned to an ISDN access andhave to be sent by the CITAM to the ISDN network during theinitializatio in oder to allow the operation of the CITAM at thisaccess (also see chapter 14).

The first SPID number is stored on storage location T.07. Iftwo different SPID numbers are available for the access, theSPID number for port 1 is stored on T.07, while the SPIDnumber for port 2 is stored on T.08.

After changing the SPID number, a RESET has to be exe-cuted manually at the CITAM (RESET key of the front panel)to execute the initialization with the new SPID numbers.

The SPID numbers are no call numbers, butcalling line identifiers. They may not bechanged, as they are prescribed by the networkprovider. A change is only necessary if theCITAM is operated at the access for the firsttime or if the access has changed.

Operation Modes 5

5 Operation Modes - 1

5 Operation Modes

There are six different ways to operate the CITAM: exclu-sively by changing the DIP switch setting, directly at the frontpanel, with the help of the Window System, via the command-orientated supervisor, with V.25bis (limited options only), aswell as with Hayes AT.In order to to use the configuration option of the Window Sys-tem or the Command Supervisor, the CITAM has to be con-nected to an external DTE.

The configuration via DIP switches is explained in detail inchapter 4. It should be pointed out here once more that all set-tings become inactive as soon as a change of the configurationis made via one of the other control elements. Conversely,however, the DIP switch configuration can be reactivated withthe help of any of these input options.

The configuration options with V.25bis are explained in section8.3. The description of the operation of the CITAM with HayesAT can be found in section 8.5.

In this chapter, the remaining three operation modes are pre-sented and explained in brief.

5 Operation Modes


5.1 Operation of the Front PanelThe application of the keys is clearly prescribed by their

designation. With the <SEL> key, something is always se-lected, as in the case of a menu selection with various options.

With the <ENT> key, an input is always activated, confirmed orconcluded.After connecting the power supply to the CITAM, the display“ISDN” appears. If a leased line was configured, this is dis-played by “S0FV” instead.

In the main menu ISDN (“S0FV”) the user reaches the desiredsubmenu by pressing the <SEL> key.

Every menu item can be aborted by using the key combination<SEL> & <ENT>. If both keys are pressed simultaneously formore than one second the CITAM jumps back to the superiormenu level in the hierarchy, resp to the main menu.

Fig. 5-1: The top hierarchy level in the front panel menu

5.1 Operation of the Front Panel


To abort a menu item, press the key <SEL>.Keep it pressed and confirm the command withthe <ENT> key to avoid unintended modifica-tions of the configuration.

With the submenu CONN a connection to a stored call numbercan be established via the front panel.

With the submenu DISC an already existing connection can beterminated manually.

With the submenu NUMB up to eight different call numberscan be entered and stored.

With the submenu CONF configuration changes can be made.In addition to the port selection, a further menu item “TA” canbe found in the menu “CONF”, which can be used to set bothports. Apart from other functions, this menu item ”TA” includesoptions for the INBAND communication which will be explainedin detail later (see chapter 9, Inband Parameter Communica-tion).

In both the menus ”CONF” (to set configurations) and “NUMB”(to set call numbers) a submenu Show/Chng can be found.When moving to further submenus with the option “Show”,configuration parameters or call numbers can only be dis-played but not modified. To change parameters or call num-bers the <SEL> key has to be pressed and be held for approx.three seconds while “Show” is being displayed, so that the dis-play changes to “Chng”. When changing into the parameter orcall number menu with the ENTER key <ENT>, the parametersor call numbers can be modified.

In the chapters 6, 7, and 13, which explain the functions, thesequence descriptions for the operation via the front panel aremarked with the following icon next to the text:

Solution: Set the DTE to “ready” or (preferably) setthe option Intf to “inactive”, if you wish tocontrol the connection via the front panel.

5.2 Operation of the Command-OrientatedSupervisor System


5.2 Operation of the Command-OrientatedSupervisor SystemOperating the command-orientated supervisor of the

CITAM, all inputs have to be entered via a command line. Inaddition, the terminal must have a certain setting to be able tocommunicate with the CITAM supervisor.

If a module C1, C2 or C3 is applied, the setting is as follows:

V.24 interface with♦ 9600 bps

♦ 8 data bits

♦ no parity

♦ 1 stop bit

Using a SW-version 4.15 or higher together with a module C5,C6 or C7 it is possible to choose the supervisor transfer rate tobe 2400, 4800, 9600 or 19200 Baud. This setting can only bechanged during the startup procedure of the CITAM as de-scribed in the following section.

For remote calls the supervisor speed on bothsides has to be set to the same value.

5 Operation Modes


Fig. 5-4: Selecting the supervisor speed viafrontpanel

After a reset or power-up only the <SEL> button has to bepushed (do not push the <ENT> button). After the CITAM startsto display the hard- and softwareinformation via the front panelthe <SEL> button has to be released and the <ENT> buttonhas to be pushed. The display changes to "SVbd " andchanges again after approx. 1 sec to the present supervisorspeed. By pushing the <SEL> button the speed can be se-lected to be 2400, 4800, 9600 or 19200 (baud). The selectionhas to be confirmed and activated by pushing the <ENT> but-ton. Afterwards the CITAM performs a reset.

If the <ENT> button is not being pushed within a 10 sec. time-out the CITAM changes into idle state keeping the supervisorspeed unchanged.

For operation of the CITAM via supervisor terminalplease note that the terminal supervisor speed atthe serial port has to comply with the supervisorspeed of the local CITAM - in case a remote super-visor speed is carried out with the supervisor speedof the remote CITAM.

5.2 Operation of the Command-OrientatedSupervisor System


With the operation of the CITAM it should be noted that thisoperation mode is not possible with a C0 resp C4 module.

Be careful to select the correct terminal (see chapter 5.3). If theterminal is connected and the CITAM and the terminal areswitched on, the CITAM prompt appears when pressing the<ENTER> or <CR> keys:

CITAM 1 >>

Users who are familiar with the operation of supervisor sys-tems should normally be able to configure and operate theCITAM without the operating instructions after a short period oftime, using the help texts of the Command Supervisor.

A general help text is displayed upon entering “?” or “HELP”.

CITAM 1 >>?

To continue, every command line has to beconfirmed by pressing the <ENTER> or <CR>key.

The Cursor Keys

The cursor keys have the following functions:

<Cursor Up> Alternate renewed display of the last2 commands

<Cursor Down> Alternate renewed display of the last2 commands

<Cursor Left> Moves the cursor to the left within theinput line

<Cursor Right> Moves the cursor to the right withinthe input line/start of the WindowSystem

Deletion of Characters

If the cursor is placed over a character, it can be canceled with:

<Backspace> or

the <DEL> key.

5 Operation Modes


Simplified Entering

The individual commands do not always have to be enteredcompletely, but only as far as that the command interpreter isable to recognize the command unambiguously. This meansthat a connection set-up with a number can be entered, as fol-lows:

CITAM 1>>Connect Port 1 #06111234567

However, the following command line has the same effect:

CITAM 1>>Co p 1 #06111234567

In the appendix a list of all commands in alphabetical order canbe found, as well as a corresponding short description withcross reference to the respective places in the manual, wherethe function of the command is explained in detail.

In chapters 6, 7, and 13, which explain all functions, the indi-vidual command descriptions are marked with the followingicon next to the text:

Fig. 5-5: Icon marking command descriptions

5.3 Operation of the Window System


5.3 Operation of the Window SystemThe Window System is activated with the command WIN

from the command-orientated supervisor system.This command is supported only if a VT100 terminal was pre-viously selected with the command SET TERMINAL x and if itwas defined that a VT100 terminal is connected (see chapter5.2).

After the Window System has been activated, a menu item canbe selected with the cursor keys “Cursor up” <↑> or “Cursordown” <↓>. The selected menu item is activated with the<ENTER> key, the <CR> key or with the cursor key “CursorRight” <→> (except after entering a digit which has to be con-firmed with <ENTER>). In addition, it is also possible to acti-vate a menu item by pressing the keys on the keyboardmarked with the symbols which are placed in front of the re-spective menu item (digit or letter). Every window can be leftwith the cursor key “Cursor left” < ←>, with <X> or by selectingthe EXIT option.

It should be ensured that the connection to theterminal is not interrupted as long as the WindowSystem is active. The Window System alwaysremains at the field where the user has stoppedediting or configuring and is set back automati-cally only after five minutes. If the terminal is re-connected during this interval, it is not clear atwhich menu item the CITAM currently remains.Therefore, the Window System should be leftcompletely until the CITAM prompt of the Com-mand Supervisor is displayed. To continue, everycommand line has to be confirmed with the<ENTER> or <CR> key.

5 Operation Modes


If the CITAM is operated in the rack, it should be noted that thisoperation mode is not possible with a C0 or C4 module.

Upon activating the menu item MORE, further CITAM optionsare displayed for selection.

6 Functions - 7

6.3 Manual Connection Set-UpA connection can be set up manually either with a stored

call number or with a call number which is directly entered(only possible at the Command Supervisor and in the WindowSystem).

For a manual connection setup with a 2-port version the re-spective port has to be selected.

Furthermore, it has to be selected from which storage locationthe call number to be dialed should be taken or the call num-ber has to be entered directly where appropriate.

After a successful connection set-up, the green LED P1 (port1) or LED P2 (port 2) shines, depending on which port wasselected. In the case of the CITAM 128, both LEDs shine aftera successful connection set-up, since both B channels are re-quired for the 128 kbps ISDN connection. Subsequently, thedisplay again indicates “ISDN”.

If the connection was established successfully, but the trans-mission line cannot be synchronized, the display blinks , andafter one minute the connection is terminated automatically ifno speed adaptation was activated (BRC/Auto Baud).

Via the submenu CONN, a connection can be set-up manu-ally, as follows:

1) Telephone number not stored (empty storage location). The display blinksfive seconds can be aborted with <SEL> or <DEL>.

2) The data terminal ready function is activated, but the DTE is not ready foroperation. The display blinks five seconds or can be aborted with <ENT>or <SEL>.

3) Connection set-up for port 1 was activated.

4) Connection set-up for port 2 was activated.

Fig. 6-4: Manual connection set-up via the front panel

If the selected storage location is empty, the display[ÎÍ]blinks for approx. 5 seconds. Then, another storage lo-cation can be selected with the help of the <SEL> button.

It is only possible to select an access which has not yet beenconnected. Every setting state can be aborted with <SEL> &<ENT>.

If the connection cannot be established successfully, the dis-play returns to CONN.

6.3 Manual Connection Set-Up

6 Functions - 9

The command CONNECT PORT n #xxx starts a connectionset-up for port n with the call number xxx.

The command CONNECT PORT n Tyy establishes a con-nection for port n with the call number which is stored on thestorage location yy (1-8) of the CITAM (cf. section 7.35).

Example 1:

The command CONNECT PORT 1 #0611123456*7 starts aconnection set-up in the 1TR6 for port 1 with the call number0611123456 and the EAZ 7 with which the correct device (respthe corresponding port) is selected on the remote side if the pa-rameter described in chapter 7.35 is set to ON.

Example 2:The command CONNECT PORT 1 T2 starts a connectionset-up for the port with the call number which is stored onstorage location 2 of the CITAM.

In the first menu the function CONNECT is selected and acti-vated for a desired connection. Then the second windowopens for selecting the port.If a connection is already established for a port, then the errormessage “ONLINE” appears after the activation. If a hardwareproblem exists at a port or the port is not available as a hard-ware component (port 2 → option), the error message “NOTPRESENT” is displayed.

If the connection is to be established to a device whose callnumber has already been stored, the function STORED hasto be selected in the next window. In the following window, allselectable call number storage locations are indicated.

A storage location can only be activated for which a call num-ber has already been assigned. If the port has already beenset up, the activation is blocked.

6.4 Manual DisconnectionApart from the automatic disconnection, the user has the

option to terminate every connection “manually”, i.e. on thebasis of a command entered explicitly by hand.

If a connection is terminated, the corresponding LED (green)is turned off.

Via the submenu DISC an existing connection can be discon-nected manually, as follows:

Fig. 6-7: Manual disconnection via the front panel

From LAYER 1 Layer 2 can be reached with the <ENT> but-ton. This LAYER can only be selected, however, if a connec-tion was previously set up for an access. The desired port canbe selected with the <SEL> button (ifa connection has alreadybeen established for the corresponding port); the disconnec-tion can be initiated with the <ENT> button.

In the case of the single-port version, LAYER 2 is not avail-able, because a selection is unnecessary.

If a disconnection was initiated manually via the front panel,which has not yet been confirmed by the ISDN network (e.g.because of alerting (see chapters 8.4.3) or in the case of anerror), the connection with can be aborted with the <SEL> &<ENT> buttons!

If the connection was terminated, the corresponding LED(green) goes out and the display returns to “ISDN”.

In the case of an error, the display returns to “DISC”.

6.5 Call Number StorageUp to eight call numbers can be stored. A call number may

consist of a maximum of 19 characters, including the subad-dress resp MSN.

Via the submenu “NUMB” call numbers can be written for theavailable eight storage locations, as follows:

LAYER 2 can be reached from LAYER 1 by pressing the<ENT> button. With the help of the “ Show” mode, unintendedparameter changes are avoided. To change parameters, theoption “Chng” has to be selected on this level. To do this, the<SEL> button has to be pressed for approximately 3 sec-onds. The system remains in this mode until the configurationmenus are left again.

On LAYER 3, one of the eight storage locations is selectedwith the <SEL> button. If the correct storage location is dis-played, the user can change onto LAYER 4 with the <ENT>button and enter the call number. To do this the digits 0 to 9have to be selected with the <SEL> button. The correct inputhas to be confirmed by pressing the <ENT> button. In addi-tion, the special characters “↑”, “↓”, and “←” are available.In each case, the second character from the left on the displaycan be changed. If the desired character has been selected,the display is shifted with the <ENT> button by one space tothe right so that the changed character is located at the firstplace to the left.

Meaning of the special characters:“↑”: If the <ENT> button is pressed, the

character which was located at thisplace is canceled , and the followingcharacters move up (delete function).

“↓”: If the <ENT> button is pressed, ablank is inserted at this place foranother character has to be entered(insert function).

“←”: This character is the end character. If the<ENT> button is pressed after this char-acter is displayed, the call number isstored and layer 3 is left (enter function).

7.11 Setting the Bit Rate AdaptationProcedureBit rate adaptation procedures are used to adapt lower

transmission rates to the transmission rate of 64 kbps requiredby the ISDN network. Two different procedures can be se-lected:

X.30 according to the X.30 protocol, which isused for X.21 services, and

V.110 according to the V.110 protocol.

The X.30 procedure is used as the default setting for serviceindicator 3, while the V.110 procedure is used for service indi-cator 7. The CITAM, however, allows it to change the proce-dures independent of the selected service indicator.

Fig. 7-24: Setting the bit rate adaptation procedure via thefront panel

With the command SET PORT n RATEADAPT xxx, the bitrate adaptation procedure according to X.30 (xxx = X.30) orV.110 (xxx = V.110) is selected for port n.

7.12 Activation/Deactivation of theInterface ProceduresThe CITAM allows the control via front panel or command-

orientated supervisors, resp Window System and via the re-spective interface. With this option, the user can select whetheronly the front panel and the supervisor/Window System are ac-tive or - in addition - the interface, as well.

IGNORE The interface signals are ignored. The frontpanel or the supervisor, resp the WindowSystem take over the complete control. Theconnection set-up and disconnection haveto be initiated manually. Incoming calls areaccepted (if the subaddress and service in-dicator match).

ACTIVE The interface procedures are active. Withthe front panel or the supervisor, resp theWindow System, a connection can only beestablished if the interface signals indicatethat a DTE is available for the selected pro-cedure by displaying the message “ready”.Incoming calls have to be accepted by theinterface procedure.It has be noted, however, that a connectionset-up does not function via the front panelor the supervisor at an active interface,since the corresponding interface signalsfor the respective procedure are not pro-vided by the DTE. The disconnection canbe executed any time via the front panel orthe supervisor (if a connection has beenestablished).

7.12 Activation/Deactivation of the InterfaceProcedures


Fig. 7-26: Activation/deactivation of the interface procedures via thefront panel

With the command SET PORT n INTERFACE xxx , the controlfor port n is activated (xxx = active) or deactivated (xxx = ig-nore) via interface signals.

7.13 Definition of the DTR Signal in theHayes AT ModeIn the Hayes AT mode, the function of the interface signal

DTR can here be determined for the CITAM.

The following three settings are available:

IGNORE The interface signal DTR is ignored.

ACTIVE The interface signal DTR has to be active.

COMMAND By switching the DTR signal, an establishedconnection changes into the commandmode.

Fig. 7-28: Definition of the DTR signal in the Hayes AT mode via thefront panel

With the command SET PORT n DTR_CONTR xxx, the DTRsignal is activated (xxx = active) for port n, ignored (xxx = ig-nore), or the established connection is switched over into thecommand mode (xxx = command).

7.14 Definition of the CTS-Signal in theAsynchronous or V.25bis ModeIn the asynchronous or V.25bis mode, the signal CTS may

behave, as follows:

Option 1: The interface signal follows the local RTS if“Intf” is set to “ign”.

Option 2: The interface signal is always set to “ON” if“Intf” is set to “ign”. For V.25bis, it followsthe CCITT recommendations.

Option 3: The interface signal follows the RTS on theremote side for transmission rates largerthan 48 kbps; otherwise, it follows the localRTS.

If the interface is activated, the CTS signal is additionally influ-enced by changes of the RTS signal, which are caused by thedialing procedures!

7.15 Definition of the DSR Signal in theAsynchronous or V.25bis ModeIn the asynchronous or V.25bis mode, the DSR signal can

be set to “ON” either permanently or after establishing a con-nection. This parameter should be set according to option 4.

The signal DSR may behave, as follows:

Option 1: The interface signal is set to “ON” only inthe case of an established connection.

Option 2: The interface signal is permanently set to“ON”.

Option 3: The interface signal is controlled by theDTR signal on the remote side if the bit rateis lower than 56 kbps. If the bit rate exceeds48 kbps, the DSR signal is set to “ON” afterestablishing a connection.

Option 4: The interface signal is set to “ON” only if thetransmission line is displayed as synchro-nized.

7.19 Activation of the Incoming Check


7.19 Activation of the Incoming CheckWith this parameter, the user can define whether the in-

coming call number is to be subjected to an incoming check(INCOMINGCHECK) (see section 4.3.3).

The evaluation is performed from the first character to the last.The characters “?” and “*” are selectable special characters forstored numbers which were only stored for a check. The char-acter “?” represents an optional digit and, thus, serves as awild card. The character “*” is used at the end of the call num-ber if it is intended to check the entire number. If the call num-ber is entered without "*" its last digit is not checked. If thecharacter "*" is used within the number, the remaining(following) digits of the call number are not checked.

The following two settings are available:

NO The incoming call number is not subject toa check.

YES The incoming call number is compared withall stored call numbers and is only admitted ifit matches one of them.

For a remote supervisor call (see chapter 9.4), an incomingcheck is executed, as well.

From SW Rev. 4.0 onwards, an incoming check is also exe-cuted for a remote supervisor call (INBAND/REMOTE set to“ON”). The local password is compared with the receivedpassword and the incoming call number (origination address inthe 1TR6 protocol, resp calling party number in the DSS1 pro-tocol) is compared with the stored call numbers. A remote su-pervisor call is only initiated if both checks are successful. Oth-erwise, the connection is terminated.

For operation of the CITAM via supervisor terminalplease note that the terminal supervisor speed atthe serial port has to comply with the supervisorspeed of the local CITAM - in case a remote super-visor speed is carried out with the supervisor speedof the remote CITAM.



Fig. 7-60: Activation of the incoming check via the front panel

With the command SET PORT n INCOMCHECK xxx , the in-coming check is activated (xxx = YES) or deactivated (xxx =NO) for port n.

With the function INCOMCHECK, an incoming check can beactivated (YES) or deactivated (NO) for the selected port.

Fig. 7-61: Activation of the incoming check via the Window System

7.20 Activation of the Localcheck


7.20 Activation of the LocalcheckThe function LOCALCHECK is intended for the use of the

CITAM in countries where the service MSN (multiple sub-scriber number) is being supported.

The evaluation is performed in reverse direction, starting withthe last digit. Only as many digits have to match as are storedon the indicated storage location.

Example : Specific subscriber number: 06074 12345

Stored test number: 345

→Only the last 3 digits have to match!

The character “?” is a special character which can be selectedfor the check number. The “?” represents an optional digit and,thus, serves as a wild card.

The following settings are available:

NONE No local call number is stored, resp se-lected.

Tnn Display of the storage location for the localcall number. With nn the storage locationcan be selected with “1” to “8”.

The LOCALCHECK always has to be activatedfor both ports.

If the function LOCALCHECK is activated theoption INBAND has to be set to BUS or to OFF.



Fig. 7-62: Activation of the localcheck via the front panel

With the command SET PORT n LOCALCHECK xxx , the lo-calcheck is activated (xxx = T1 - T8) or deactivated (xxx = NO)for port n by selecting a call number storage location.

With the function LOCALCHECK , the localcheck can be acti-vated (YES...) or deactivated (NO) for the chosen port by se-lecting a call number storage location. In the last window thestorage location is selected where the local calling number isstored.

7.21 Activation of the SLOW DIAL Function


7.21 Activation of the SLOW DIALFunctionWith SLOW DIAL, an option is available for the X.21 dialing

procedure, which executes the dialing procedure with 9.6 kbpsat a configured data transmission rate of 64 kbps.

In the case of a normal configuration, the transmission rate isnot distinguished into the data transmission phase and thecommand phase. This means that for a desired data transmis-sion with 64 kbps the dialing procedure has to be executedwith 64 kbps.

When setting the option SLOW DIAL to “ON”, the dialing pro-cedure is executed with 9.6 kbps and is switched over to theconfigured rate of 64 kbps after the connection set-up.

If this option is set to “OFF”, both the dialing procedure and thedata transmission are performed with 64 kbps.


OFF Normal configuration. Command and datatransmission phase with 64 kbps.

ON Command phase with 9.6 kbps and datatransmission with 64 kbps.

Fig. 7-64: Activation of the SLOW DIAL function via the front panel



With the command SET PORT n SLOW_DIAL xxx , the func-tion SLOW DIAL is activated (xxx = “ON”) or deactivated (xxx= “OFF”) for port n.

With the function SLOW DIAL , the function SLOW DIAL canbe activated (“ON”) or deactivated (“OFF”) for the selectedport.

7.22 Selection of the ISDN Connection Type


7.22 Selection of the ISDN ConnectionTypeThe function ISDN MODE (resp “Conn” for “ISDN connec-

tion”) serves to select the desired ISDN connection.


Option 1: S0FV (up to SW version 4.11) = leased lineMIXMODE (from SW version 4.12 onwards) =leased line only for the corresponding port.If both ports are to be operated in theleased line mode, the setting “S0FM” has tobe selected via the DIP switches.

In the case of the setting “MixMode”, it has to beobserved that only the configuration of the pa-rameters transmission rate (cf. section 7.8) andoperation mode (cf. section 7.2) are permitted todeviate from the default configuration. In addition, itshould be observed that the parameter for the ac-tivation/deactivation of the interface proce-dures (cf. section 7.12) is set to “ignore”.

Option 2: Normal dial-up line

Option 3: Semipermanent dial-up line

Option 4: TIMELINK = tariff structure depends on theconnection time (only available in Australia)

During the operation with a leased line connection, the configu-ration can only be changed manually via the DIP switch andthe subaddress rotary switch (cf. chapter 11).

7.23 Automatic Rate Adaptation withINBANDThis parameter serves for the automatic rate adaptation

between two CITAMs in the INBAND mode (synchronousmode).

The option “AutoBaud” functions only if the optionINBAND was previously set to “ON”, resp BUS (cf.7.29).

AutoBaud has a higher priority than “BRC” (cf.7.24).

In the case of automatic rate adaptation, INBAND (AutoBaud)principally has priority over BRC. A conflict at different settingsis not possible.

If INBAND/AutoBaud is deactivated or an INBAND communi-cation is not initiated, a rate adaptation via BRC is possible.

Corresponding messages are displayed at the supervisor ter-minal for different modes (synchronous/asynchronous) orrates.

The option “AutoBaud” can be separately activatedfor every port.

7.23 Automatic Rate Adaptation with INBAND



Option 1: (Upper). The received rate information isevaluated. If the set rate of the calling sideis equal or higher than the locally set rate,the rate is adapted on the local side and theconnection is set up. If the set rate on thecalling side is lower than the rate on the lo-cal side, an error message is returned withthe local rate, and the calling side has toadapt its rate if a connection is to be set up.

Option 2: (Lower) With this parameter, the connectionis only set up at equal or lower rates. Oth-erwise, an error message is returned withthe local rate, and the calling side has todecide whether the connection is to be setup or not.

Option 3: (Upper & Lower) With this parameter theCITAM adapts itself to every rate.

Option 4: (OFF) With the parameter “OFF”, the auto-matic rate adaptation in the INBAND is lo-cally switched off, but the rate information istransmitted in the INBAND to the remoteside.



Fig. 7-68: Configuration of the automatic rate adaptation withINBAND via the front panel

Option 1: Upp

Option 2: Low

Option 3: UpLo

Option 4: OFF

With the command SET INBAND AUTOMATIC BAUD PORTn yy , the automatic rate adaptation with INBAND is configuredfor port n, as follows:

Option 1: yy = UPPER

Option 2: yy = LOWER

Option 3: yy = UP/LO

Option 4: yy = OFF



With the function AUTOBAUD , the automatic rate adaptationwith INBAND can be configured for the selected port, as follows:

Option 1: UPPER

Option 2: LOWER

Option 3: UP/LO

Option 4: OFF

Fig. 7-69: Configuration of the automatic rate adaptation with INBANDvia the Window System



7.24 Automatic Rate Adaptation withBearer Rate CheckThe function bearer rate check serves to support the rate

information in the SETUP of an ISDN call. With this option, theset bit rate can be sent as an information to the remote termi-nal in order to adapt the remote bit rate, if appropriate.

The prerequisite for this option is the support viathe ISDN network. Otherwise, an error messageis displayed. A connection set-up is possibleagain only if the option bearer rate check is set to“OFF”.This function is only supported for a synchronousdata transmission, as a rate adaptation for asyn-chronous DTEs does not make sense.The option BRC can be separately activated forevery port.In addition to the BRC, a rate adaptation is alsopossible via INBAND (AutoBaud). In this case,INBAND (AutoBaud) has priority over the BRC(see chap. 9, INBAND parameter communica-tion).

7.24 Automatic Rate Adaptation with BearerRate Check


Five different parameters can be selected to activatie this op-tion:

Option 1: (Off) With the parameter “OFF”, the rateinformation is not sent with a SETUP and isnot evaluated in the case of an incomingcall.

Option 2: (Upper). If this parameter is set, the rateinformation is sent with the SETUP. In thecase of an incoming call, the received rateinformation is evaluated.Only if the received rate information isequal or larger than the set rate, the rate isadapted locally and the connection set up.

Option 3: (Upper & Lower) With this parameter, theCITAM adapts itself to every rate.

Option 4: (ON) (SW Rel. 4.03 and later releases)With the parameter “ON”, the rate informa-tion is sent with a SETUP; no automaticrate adaptation takes place.

Option 5: (Lower) With this parameter, the connectionis only set up at an adapted rate at equaland lower transmission rates.

7.25 INBAND CALLBACKWith this INBAND function, the CITAM can request a call-

back, e.g. to cause charges over large data volumes occurspecifically at a certain place. In this case, only the charge fortransmitting the callback request becomes effective.

If a call number transmission is not supported bythe ISDN, the LOCALCHECK has to be activated!

Furthermore, the LOCALCHECK also has to be activated if theport requesting the callback is not operated at the default callnumber of the access (DSS1 - MSN, 1TR6 - EAZ). If the pa-rameter LOCALCHECK is activated the local calling number isbeing sent in the INBAND.

To select this option, the following parameters can be used:

Option 1: (No/Ignore) No callbacks are requestedat a connection set-up.Incoming requests are ignored and rejectedon the calling side with an error message.

Option 2: (No/accept) No callbacks are requestedat a connection set-up. Incoming callbackrequests are accepted and carried out.

Option 3: (Yes/ignore) If a connection is set up, theinformation for a callback request is trans-mitted.Incoming callback requests are ignored andrejected on the calling side with an errormessage.

Option 4: (Yes/accept) If a connection is set up, theinformation for a callback request is trans-mitted.Incoming callback requests are acceptedand carried out.

7.30 Entering and Changing the Password


7.30 Entering and Changing the PasswordWith the option of the INBAND communication between two

Controlware devices it is possible to protect a password for theISDN connections.

The entering is executed according to the entering of the callnumbers. Uppercase and lowercase letters are distinguished.

The password is limited to a fixed length of 10 characters, i.e.its length cannot be changed. There is a hardware defaultpassword, which consists of the last 10 digits of the internal se-rial number.

Fig. 7-82: Entering and changing the password via thefront panel

The arrow to the left “←” is a special character. It can only beselected from the first character of the password.If “←” is selected and the <ENT> key is pressed, the hardwaredefault password is activated. If the password display is leftby pressing the keys <SEL> & <ENT>, the change made isdiscarded.With the command SET INBAND PASSWORD @[ zzz], thepassword for the remote configuration, resp for all ISDN con-nections can be entered, resp changed.

“[zzz]” represents a password with a maximum of 10 characters.When entering less than 10 characters, the missing charactersare substituted by “0” characters. If the character behind “@” ismissing, “0000000000” is being sent as password.



If the entering of the password is started at the terminal withthe <DELETE> key, the presetting with the serial number isactivated. With the <RETURN> key, the password is takenover. If the <DELETE> key is pressed at another step, the in-put area is automatically filled with “0” characters.

7.31 Configuration of the PasswordProtection


7.31 Configuration of the PasswordProtectionWith the option of the INBAND communication between two

Controlware devices, it is possible to protect a password for theISDN connections. This password may be valid for all ISDNconnections or only for connections, which are set up for a re-mote configuration (see chapter 9.4).

Option 1: for remote configuration only

Option 2: for all ISDN connections

A detailed description of these setting options is given in sec-tion 9.2.1.

Fig. 7-84: Configuration of the password protection via the front panel

7.32 Enabling Remote Supervisor Calls


7.32 Enabling Remote Supervisor CallsWith this parameter, it is possible to reject incoming remote

supervisor calls if it is not desired that the device can be con-figured on a remote side.

This parameter can only be changed via the local supervisor. Itcannot be modified via a remote supervisor call.

Fig. 7-86: Enabling /disabling of remote supervisor calls via thefront panel

With the command SET INBAND REMOTE xx, the option re-mote supervisor call can be switched off (xx = OFF) andswitched on again (xx = ON).



Fig. 7-87: Enabling /disabling of remote supervisor calls via theWindow System

For SW releases up to 4.13 remote supervisor calls are possi-ble with activated Inband only (Inband set to ON or BUS). ForSW releases 4.15 and higher remote supervisor calls forCITAM modules C5, C6, C6M and C7 are made possible al-though Inband is set to OFF at the called CITAM because theremote supervisor call can be defined by the subaddress. Asubaddress for the remote supervisor call can only be definedvia the frontpanel.

7.32 Enabling Remote Supervisor Calls


Fig. 7-88: Accepting a remote supervisor call with INBAND set to OFF

With Inband deactivated push the <SEL> button after a reset orpower-up (do not push the <ENT> button). After the CITAMstarts to display the hard- and softwareinformation via the frontpanel the <SEL> button has to be released and the <ENT>button has to be pushed. The display changes to "SVbd " andchanges again after approx. 1 sec to the present supervisorspeed which has to be confirmed by pushing the <ENT> but-ton.

The display first shows "ok ", then changes to "ReSV". Afteranother 1 second the current setting is displayed. The defaultsetting "Inbd " represents the conventional remote supervisorfunction with INBAND set to ON or BUS. By pushing the<SEL> button the different subaddresses, which will activatethe remote supervisor function although Inband is set to OFF,are represented by the displays "Sub1" to "Sub8". The selec-tion has to be confirmed and activated by pushing the <ENT>button. Afterwards the CITAM performs a reset.



Please note that the subaddress which is sup-posed to indicate a remote supervisor call is as-signed a special value that is not already in use forthe subaddresses of the CITAM ports.

Please note that during the remote call INBAND isactivated (if a two port CITAM is used the secondport tries to handle INBAND during the remote su-pervisor call).

7.33 The Remote Supervisor CallWith the command CONNECT REMOTE #xxx @[zzz] orCONNECT REMOTE Tyy @[zzz], a remote configuration callcan be initiated. As in the case of a normal call, it is possibleto enter the call number directly or to dial a stored call number.

“#xxx ” is used if a call number is to be entered directly. “xxx ”represents the call number, which is always preceeded by thecharacter “#”.

If a stored call number is to be dialed, “Tyy ” has to entered.The storage location (yy = 1-8) is preceeded by the character“T”. The password is marked with the character “@”. Thecharacter “[zzz] ” represents the actual password.

If less than 10, but more than 1 character are displayed after“@“, the missing characters are substituted by “0”.

If no character follows after “@”, “0000000000” is being sent aspassword.

A remote configuration call is set up with the command DISCREMOTE.

It is possible to enter a call number directly or to dial a storedcall number.

a) Dialing a Stored Call Number

7.33 The Remote Supervisor Call


Fig. 7-89: Initiating a REMOTE configuration call by dialing a storednumber

b) Direct Entering of a Call Number

The presetting for the password always consists of 10 “0”characters. The password setting is valid, as long as the se-lection menu “STORED”, “KEYBOARD”, “PASSWORD” is notleft to the left hand side.If the menu is left to the left hand side or the connection to theremote terminal is successfully set up, the password to betransmitted is reset to the presetting with the 10 “0” characters.



7.34 Configuration for the VersionsCITAM 128 and CITAM BYTETIMINGTwo versions are available for the CITAM to fulfill special

requirements.

The CITAM Bytetiming is equipped with a daughter board toprovide a byte clock at the interface. With the byte clock, it canbe determined where a byte starts or end in the data stream.

The CITAM 128 is equipped with a daughter board to set up aconnection with 128 kbps. To do this, two B channels are set upand multiplexed. This multiplexing procedure is CITAM-specificand can only be applied for connections between two CITAMs128. A propagation time compensation is made.

The connection set-up for port 1 is performed according to thestandard procedure. The call number for the second channel canbe configured. It is possible to call the number twice or to dial aninternally stored call number as the second call number.

The daughter boards are automatically identified by the CITAMsoftware. As a consequence, the activation is only possible af-ter the identification.

The following settings are selectable:

inactive Deactivation of the daughter board. TheCITAM works as usual.

SPEED128 The daughter board 128 is activated.

BYTETIMING The bytetiming daughter board is activated.

If SPEED 128 was selected, the call number has to be set withwhich the second channel is to be configured. To do this, theindicated call number can be dialed twice (copy), or a callnumber available on the storage locations T.01 to T08 can beused.

7.34 Configuration for the Versions CITAM128 and CITAM BYTETIMING


Fig. 7-91: Configuration for the versions CITAM 128 andCITAM BYTETIMING via the front panel

If S128 was selected, the call number has to be set with whichthe second channel is to be configured. To do this, the indi-cated call number can de dialed twice (copy ) with ScNu, or acall number available on the storage locations (T.01 - T.08)can be used.



Fig. 7-92: Setting of the call number for the second channel for theCITAM 128 via the front panel

With the command SET DBOARD INACTIVE, the daughterboard is ignored and the CITAM is operated as usual.

With the command SET DBOARD BYTETIMING, the CITAMwith the daughter board Bytetiming is activated to make thisfunction available at the interface.

With the command SET DBOARD SPEED128 /yy, the CITAMwith the daughter board Speed 128 is activated. The secondchannel is set up with the call number on storage location yy =T.01 - T.08.

With the command SET DBOARD SPEED128 /COPY, theCITAM with the daughter board Speed 128 is activated. Thecall number is copied from port 1 and is also used to set upthe second channel.

7.35 Adding the EAZ to the Call NumberThis parameter serves to select whether the EAZ (1TR6) is

copied as the last digit to the call number or not. In the 1TR6protocol used in Germany it only has to be indicated as the lastdigit of the call number.

Selectable options are, as follows:

OFF The EAZ is not automatically copied to thecall number.

ON The EAZ is automatically copied to the endof the call number (default setting).

Fig. 7-95: Adding the EAZ to the call number via thefront panel

With the command SET SUB_ADD xx , it can be selectedwhether the EAZ is copied as the last digit to the call number(xx = ON) or not (xx = OFF).

7.36 Activation of the Function B-CHANNEL-MAPPINGIn Great Britain, the B channels are permanently allocated to

the ports. This means that the channel B1 is permanently allocatedto port 1 and channel B2 to port 2. This is only possible at ac-cesses which do not support an EAZ or MSN. Subaddress 1,however, has to be assigned to port 1 and subaddress 2 to port 2.

This configuration is only supported by ISDN software of theUK. It is ignored by all versions for all other countries .

ON The port selection is performed via the in-formation provided via the B channel.

OFF The conventional EAZ or MSN procedure isactivated.

Fig. 7-97: Activation of the function B-CHANNE-MAPPING viathe front panel

With the command SET DEBUG BCHMAP [ xx ], the functionB-CHANNEL-MAPPING is activated (xx = ON) or deactivated(xx = OFF).

7.37 Activation of Modifications of theV.25bis Procedure


7.37 Activation of Modifications of theV.25bis ProcedureWith this parameter, the V.25bis procedure can be modi-

fied, as follows.

With CONNECT, the CTS signal is set to “OFF” for 1.6 sec-onds (normal time span: 500 ms). Furthermore, incoming callsare immediately accepted and are forwarded after the syn-chronization (normally delayed for 2 sec).

NORMAL The V.25bis procedure is performed asusual.

SPECIAL The modifications are activated, as de-scribed above.

Fig. 7-98: Activation of modifications of the V.25bis procedure via thefront panel

With the command SET DEBUG V25BIS NORMAL , the V.25bisprocedure is not changed. With the command SET DEBUGV25BIS SPECIAL, the modifications can be activated, as de-scribed above.



The modification of the V.25bis cannot be configured via theWindow System.

7.38 Activation of the Automatic ProtocolIdentification


7.38 Activation of the AutomaticProtocol IdentificationThis parameter is relevant in Germany only!

With this function, one of the two German protocols 1TR6/DSS1 can be permanently set. Alternatively, they are auto-matically identified and activated. CITAM automatically exe-cutes a RESET after every modification of this parameter!

Auto Automatic protocol identification is activated.

ETSI The D channel protocol is permanently setto ETSI.

1TR6 The D channel protocol is permanently setto 1TR6.

During the operation at PBXs, the protocol shouldbe permanently set.

If automatic protocol identification is activated, the identifiedprotocol (1TR6 or DSS1) appears in the place of ISDN at thedisplay of desktop devices.



Fig. 7-99: Activation of the automatic protocol identification via thefront panel

With the command SET DEBUG AUTOPROT [ cc], one of thetwo German protocols 1TR6 (cc = 1TR6) or DSS1 (cc = ETSI)can be permanently set. Alternatively, the protocol is automati-cally identified and activated (cc = AUTO).

7.42 The Parameter SHORT HOLD MODEThe short hold mode is only available as an option. A de-

tailed description is given in the addendum, which is added forthe implementation of this parameter.

Fig. 7-103: Setting of the parameter SHORT HOLD MODE via thefront panel

With the command SET DEBUG SHMODE [ff], the parameterSHORT HOLD MODE is set (ff = see addendum).

The parameter SHORT HOLD MODE cannot be configured viathe Window System.

7.43 The Parameter BCCOPY


7.43 The Parameter BCCOPYThis parameter determines whether the rate information for

an outgoing call is to be transmitted in LLC (low-layer compati-bility) only or in BC (bearer capability) and LLC.

For BCCOPY = “OFF” (default setting), the rate information foran outgoing call (BRC = ON/LO/UP/UP-LO) is only sent in theLLC to the ISDN network, with the following exception: In thecase of transmissions with 56 kbps, this information is never-theless transmitted in BC. If the setting BCCOPY = “ON” is se-lected, the rate information is transmitted in LLC and BC.

With this setting, the compatibility of outgoing calls with oldersoftware versions is achieved. In the case of an incoming call,first the BC and then the LLC is evaluated by the new softwareversions. A compatibility to old software versions is alsoachieved in this case. The LLC obtains priority over the BC.

Fig. 7-104: Setting the parameter BCCOPY via the front panel

7.44 Setting of a CO Switch and of theSPID Number for the SW Versionsfor North America andCUSTOMNET Australia

Setting of a CO Switch

This parameter is only implemented in the North American orAustralian CUSTOMNET CITAM ISDN software. It defines onwhich “Central Office Switch” (CO Switch) the CITAM is to beoperated (also see chapter 14).

The CITAM is initialized for the respective switch. The SPIDnumbers required for the initialization of the CITAM are as-signed by the network provider.


Option 1: An AT&T 5ESS CO Switch with software5E8 or later versions (e.g. 5E9) is used.

Option 2: An AT&T 5ESS CO Switch with software5E7 or older versions (e.g. 5E6, 5E5) isused.

Option 3: A Northern Telecom DMS-100 CO Switch isused.

Option 4: Another CO Switch is used, which worksaccording to National ISDN-1.

For the CUSTOMNET SW, a switch should alwaysbe used which works according to National ISDN-1.

7.44 Setting of a CO Switch and of the SPIDNumber for the SW Versions for North America

and CUSTOMNET Australia


Setting of a SPID Number

SPID numbers (service profile identifier) are assigned by thenetwork provider. If the CITAM is only equipped with a singleport, only one SPID can be entered.

With the exception of the switch AT&T 5E6 (no SPID num-bers), two SPID numbers have to be configured for double-portCITAMs.

The call number storage locations 7 and 8 are reserved forSPID numbers, i.e. only 6 storage locations are available forcall numbers.

If SPID numbers are used, the local check has tobe activated, as well.

After entering a SPID number or modifying a parameter, theCITAM executes a reset.

8 CITAM Procedures - 1

8 CITAM Procedures

The CITAM provides five different procedures to set up aconnection:

♦ Manual connection set-up(see section 8.1)

♦ Connection set-up via interface signals(see section 8.2)

♦ V.25bis dialing procedure(see section 8.3)

♦ X.21 dialing procedure(see section 8.4)

♦ Hayes AT(see section 8.5)

8.1 Manual Connection Set-UpSetting requirement:

Ignore interface signals (see section 7.12)

A connection set-up can be performed via the front panel but-tons, resp the supervisor (see section 6.3) only, provided thetransmission speed setting corresponds with the setting of theremote unit.

An incoming call is automatically accepted in the 1TR6 if theservice indicator, the EAZ and, possibly, an INCOMINGCHECKof the number match. If LOCALCHECK is activated, an in-coming call is only accepted if the EAZ matches.

Correspondingly, the BC and MSN have to match in the DSS1.If LOCALCHECK is activated, an incoming call is only ac-cepted if the MSN matches.

8 CITAM Procedures


8.2 Control via Interface SignalsThere are five different types to perform automatic dialing

via interface signals:♦ DoDT - Dial on DTR (see section 8.2.1)

♦ DoRT - Dial on RTS (see section 8.2.2)

♦ DoDC - Dial on DiC (108/1) (see section 8.2.3)

♦ DoC - Dial on C (see section 8.2.4)

♦ DoDa - Dial on Data (see section 8.2.5)

♦ Dalw - Dial Always (see section 8.2.6)

Alternate Number Dialing

If automatic dialing via interface signals is to be carried out theCITAM performs alternate number dialing.

If "Retry" (refer to chapter 7.17) is being set to a value be-tween 1 and 15 and a connection setup was not successfulafter the corresponding number of attempts the CITAM startsto set up a connection by dialing the number stored in the nextstorage location. If again after the corresponding number ofattempts no connection could be set up the following number isbeing dialed. If a storage location is empty the CITAM againstarts to dial the number that was selected originally.

8.2 Control via Interface Signals


8.2.1 DoDT - Dial on DTRSetting requirements:

Interface procedure V.25bis (see section 7.2)


Selection of the interface signal RTS(see section 7.17b)

Selection of the call number which is to be dialedautomatically (see section 7.17b)


(see section 7.17b)


If the signal RTS is set to “ON” by the DTE, the call number ofthe indicated storage location is automatically dialed. If theRTS is set to “OFF”, the connection is terminated.

An incoming call is automatically accepted and can only beterminated by the calling station or via the front panel, resp thesupervisor. To execute this function, the DTR has to be set to“ON”. If the DTR is set to “OFF”, an incoming call is rejected oran existing connection is terminated.



8.2.3 DoDC - Dial on DiC Direct call (108/1)Setting requirements:


and/or



Selection of the interface signal DiC(see section 7.17b)

Selection of the call number which is to be dialedautomatically (see section 7.17b)


(see section 7.17b)


If the signal DiC (X.21bis signal 108/1 – switch on transmissionline) is set to “ON” by the DTE, the call number of the indicatedstorage location is automatically dialed.

If the DiC (108/1) is set to “OFF”, the connection is terminated.An incoming call is indicated with the interface signal CI set to“ON” and has to be accepted with DiC (108/1) set to “ON”within two seconds. Otherwise, the call is rejected.

The connection is terminated again with DiC (108/1) = “OFF”.

8 CITAM Procedures


8.2.4 DoC - Dial on CSetting requirements:


and/or

Interface procedure X.21 (see section 7.2)


Selection of the interface signal C(see section 7.17a)

Selection of the call number which is to be dialedautomatically (see section 7.17a)


(see section 7.17a)

Setting of a Calldelay (see section 7.17a)

If C is set to “ON” by the DTE, the call number of the indicatedstorage location is automatically dialed. If C is set to “OFF”, theconnection is terminated. An incoming call is automatically ac-cepted and can only be terminated by the calling station or viathe front panel, resp the supervisor.



8.2.5 DoDa - Dial on DataSetting requirements:


and/or


Selection of the interface signal (Data)(see section 7.17c)

Selection of the call number which is to be dialedautomatically (see section 7.17c)


(see section 7.17c)

Setting of the Calldelay to 0 (see section 7.17c)

If the DTE is transmitting data and the DTR signal of the DTEis set to “ON”, the number of the indicated storage location isautomatically dialed. The connection set-up may last 1 to 5seconds (national calls). In the case of international calls,larger waiting periods may occur.

The connection is only maintained as long as as the DTE istransmitting data and the DTR is signaling “ON”. If the DTE isnot transmitting data, the DTR, however, is set to “ON”, theconnection is terminated after the indicated period of time (inminutes). If the DTR is set to “OFF”, the connection is alsoterminated.

An incoming call is automatically accepted, if the DTR signal ofthe DTE is set to “ON”. The connection is maintained as longas as the local DTE is transmitting data or if the set time hasnot yet expired and no data are transmitted.

If the DTR is set to “OFF”, the connection is terminated.

It has to be ensured that the local DTE transmitsdata within the time set with “Dmin”, since thereceived data do not reset the “Dmin” timeout andthe connection is terminated after the timeout.

8 CITAM Procedures


8.2.6 Dalw - Dial alwaysSetting requirements:


Selection of the interface signal (Dial Always)(see section 7.17)

Selection of the call number which is to be dialedautomatically (see section 7.17)


(see section 7.17)

Setting of the Calldelay (see section 7.17)

When using the function Dial always, the CITAM behaves at adial-up line access similarly as a CITAM which is operated at aleased line access.

According to the setting of the AutoDial parameters, the CITAMstarts dialing the set call number immediately after the supplyvoltage is turned on. Although the interface of the CITAM hasto be active to activate the Dial always functions (menu Auto-Dial), all interface signals are ignored.The Dial always function also executes alternate number dial-ing (see chapter 7.17) if the retry value is set to a value rangingfrom 1 to 15 and if no connection is set up after the dial at-tempts.

If the parameter SUCCESS has been activated, the CITAM di-als the set call number until the connection is successfully setup.

The function Dial always is especially used for test purposes orfor local area connections which have a sufficiently long tariffrate clock.

8.3 CITAM and V.25bis Procedure


8.3 CITAM and V.25bis ProcedureThe CITAM does not differentiate the transmission rate into

the data transmission phase and the command phase. If thedata transmission is to be performed with 64 kbps, the dialingprocedure also has to be executed with 64 kbps.

V.25bis commands can only be entered via the physical inter-face(s) of the CITAM (not via the Command Supervisor or theWindow System).

Setting requirements:

In order to establish a connection, to accept anincoming call or to configure options via V.25biscommands, the interface signal S1 (DTR) has tobe set to “ON” by the DTE!



Selection of the interface signal(see section 7.17b/C)

Automatic dialing deactivated, interface procedureactivated (see section 7.17b/C)

It should be observed that the interface signalCTS follows the CCITT recommendations onlywith the setting CTS = “ON”. All other settingslead to deviations of major or minor degree.

8 CITAM Procedures


8.3.1 ProtocolsThe V.25bis procedure can be used with three different

protocols:

8.3.1.1 Asynchronous Mode

It should be observed that the correct transmission rate andcharacter format are selected.

In the asynchronous mode, the option “Echo” causes theCITAM to retransmit the entered characters in the commandmode; thus, the entered commands become visible at an asyn-chronous terminal.

♦ Command signal ASCII 7 bits, even parity

♦ 1 stop bit

8.3.1.2 Synchronous Mode

Byte-Orientated (BSC)In the byte-orientated synchronous mode, the following settingsare required:♦ Command signal ASCII 7 bits, odd parity or

♦ EBCDIC 8 bits

Command in the frame:

SYN SYN STX “command” ETX

SYN = synchronous character, 16H for ASCII

32H for EBCDIC

STX = start of text, 02H

ETX = end of text, 03H

The individual, consecutive characters consist of 8 bits.

The previously selected character set (ASCII/EBCDIC) has to be observed.



Bit-Orientated (HDLC)In the bit-orientated synchronous mode, the following settingsare required:♦ Command signals ASCII 7 bits, parity ignored

or

♦ EBCDIC 8 bits

Command in the frame:

The global address 11111111 is used as the address. Thecontrol field marks an “unnumbered” information with a set Pbit.

8 CITAM Procedures


8.3.2 V.25bis Commands for the Connection Set-UpThe digits 0 to 9 may be used as call numbers. The special

characters P, T, W, > , < , : , . , =, _ and & are also permitted;they are ignored, however, as they are not significant for theoperation of a terminal adapter.

8.3.2.1 CRN xxxx

Connection set-up with entered call number

(max 19 characters; CRN = call request with number).

Example: CRN 0607412345*6

CRN 0607412345/6

06074 - Local area prefix code

12345 - Call number

6 - Subaddress of the calledaccess

8.3.2.2 CRI XXXX;YYYY

Connection set-up with entered call number (max 19 charac-ters; CRI = call request with identification). If the connection isnot set up, the identification is sent into the network. Thiscommand is only available for reasons of compatibility. TheCITAM executes this command like the CRN command; theidentification number is ignored.

Example 1: CRI 0607412345*6; 98265

CRI 0607412345/6; 9826506074 - Local area prefix code

12345 - Call number

6 - Subaddress of the called access

; - Separation character of the twonumbers

98265 - Identification number is ignored

Example 2: CRI 06074982642- without identification



8.3.2.3 CRS xx

Connection set-up with stored number (CRS = call requeststored number). For„ xx“ the storage locations 1 to 8 can beentered.

Example: CRS 2♦ Dials the call number which is stored in the

CITAM on storage location 2.

8.3.3 V.25bis Disconnection CommandsIn the V.25bis mode, an established connection can only be

terminated with the interface signal DTR by the DTE. If theDTR signal is set to “OFF” at the DTE, the connection is termi-nated immediately. The DTR signal should be set to “OFF” fora minimum duration of 500 ms to terminate the connection.

8.3.4 V.25bis Programming Commands

8.3.4.1 PRN n; xxxxx

Programming of a call number on one of the storage locations1 to 8 (PRN = program requested number; the call number mayconsist of a maximum of 19 characters).

Example: PRN 5;98264*2

PRN 5;98264/25 - Storage location (1 to 8)

98264 - Call number

2 - Subaddress of the called access.

8.4 CITAM and X.21 Procedure


8.4 CITAM and X.21 ProcedureAt the X.21 interface, selection signals and data are sent by

the data terminal equipment (DTE) on line T to the network; online R, the network transmits service signals and data of thetransmission partner.

Line C allows the DTE to control the service performance ofthe network. On line I, the network of the DTE displays the in-ternal states. On line S, the network of the DTE transmits thereceive clock and the transmitting clock.

At an activated interface, an incoming call is immediately ac-cepted, according to the default setting, if the C signal and theconnected DTE are active.

In the case of a normal configuration, the transmission rate is notdistinguished into data transmission phase and command phase.This means that at a desired data transmission with 64 kbps thedialing procedure also has to be performed with 64 kbps.

Nevertheless, an option is provided for the X.21 dialing proce-dure, which executes the dialing procedure with 9.6 kbps at aprogrammed data transmission rate of 64 kbps.

This is done with the option Slow Dial (see section 7.21). If theoption is set to “ON”, the dialing procedure is executed with 9.6kbps. After the connection set-up, the configured 64 kbps areset. If this option is set to “OFF”, the dialing procedure and thedata transmission are executed with 64 kbps.

Setting requirements:Synchronous mode (see section 7.2)

and/or

Interface procedure X.21 (see section 7.2)


Automatic dialing deactivated(see section 7.17a)

Take care to select the correct transmission ratefor your settings!

8 CITAM Procedures


8.4.1 X.21 Feedback

SYN = At least two consecutive synchronization characters16H.

IA5 = Signaling, coded according to the internationalalphabet No.5 (ASCII) (service signals).

BEL = Signaling an incoming call 07H.

Data format: 8 data bits

odd parity

1 stop bit

If the setting “Additional Information” is selected, the call num-ber is sent in the case of an incoming call after the DTE hasaccepted the call.

Format: SYN SYN * Call Number + SYN.If a connection is set up, the momentary time and the currentdate are additionally sent.

Format: SYN SYN /5/ DD.MM.YY hh:mm + SYN

These data, however, are only sent if the networksupports these options. If the setting “Normal” isselected, this additional information is not pro-vided.



8.4.2 The Alerting FunctionThe alerting function is a special feature of the X.21 dialing

procedure and works independently for both ports. Incomingcalls are only confirmed, but not accepted.

The called subscriber has approx 2 minutes to accept the callmanually; otherwise, the call is terminated by the network.

An incoming call is accepted if the DTE sets the C signal of theX.21 interface to “ON”. If the CITAM is in the ALERT state, thecorresponding port is busy (LED shines).

The alerting function is only active for INBAND =“OFF”.

If a manual connection set-up is initiated via the front panel, theoutgoing call is aborted by pressing the <SELECT> or<ENTER> button, as long as the ISDN network does not re-spond with a CONNECT message.

8 CITAM Procedures


8.4.3 X.21 Error CodesIf a connection request is not executed, the following X.21

error codes are sent, according to reason of the error.

Tab.: X.21 Error Codes

IA5 = Signaling; coded according to the international alpha-bet No. 5 (ASCII) (service signals).

BEL = Signaling an incoming call 07H.

8.5 CITAM and Hayes AT


8.5 CITAM and Hayes ATThe AT commands represent a widespread method to con-

trol modems with asynchronous interfaces.As it is desirable that the CITAM allows the uncomplicatedswitching from conventional dial modems for the telephonenetwork to a terminal adapter for the ISDN, the interface pro-cedure Hayes AT was implemented.

Hayes AT commands can only be entered via the physical in-terface(s) of the CITAM (not via Command Supervisor or Win-dow System).

Not all commands and S registers of this procedure have beenimplemented, according to the function of the CITAM, sincemany AT commands and configurations only make sense forthe operation of a dial modem.

Hayes AT commands principally begin with the letters “AT”.Accordingly, a command is only executed, if it begins with “AT”.

The automatic adaptation of the data transmis-sion rate to the terminal is not supported by theCITAM.

Setting requirements:


and/or

Interface procedure Hayes AT (see section 7.2)


Selection of the interface DTR signal(see section 7.17c)

Automatic dialing deactivated, interface procedureactivated (see section 7.17c)

8 CITAM Procedures


Take care to select the correct transmission rateand character format (“Frame”) for your settings!With the option “Echo”, the terminal adapterCITAM can be initiated to resend the enteredcharacters in the command mode; consequently,the entered commands are displayed on anasynchronous terminal. If the terminal is con-nected, it has to be observed that only 7 bits areevaluated in the case of command signals.



8.5.1 Hayes AT Commands for theConnection Set-UpThe Hayes AT commands listed below are combinable!

Both single commands and strings of combined commandsbegin with “AT …” The actual command follows in the thirdplace. The command “AT” alone generates an “OK” message(configuration-dependent).

If several commands are to be combined, the commands haveto entered without separating blanks after the leading “AT” orother separating characters have to be entered in a string.

The following single commands entered consecutively havethe same function as the indicated command string:

Example: Single command: ATE; ATQ; ATS

Command string: ATEQS

If a command is not combinable, this is marked with a note“(not combinable!)”!

8.5.1.1 ATD (not combinable!)

Depending on whether the connection is to be set up with a di-rectly dialed or a stored number, the ATD command is followedby the characters 0 - 9. In this case, the special characters T,P, W, @, and the comma character “,” are ignored.

Example: ATDT061519220054 - Direct dialing of theentered call number

“S” with a number from 1 to 10. The stored callnumber of the selected storage location (1-8) isdisplayed.

Example: ATDS2 - Dialing of a stored number.

8.5.1.2 ATO

The command ATO serves to return into the data mode in thecase of an established connection.

8.5.2 Hayes AT Disconnection Command ATHThe command ATH serves to terminate an existing connec-

tion. The command can only be entered in the command mode.Therefore, the data mode “+++” has to be left with the escapecode first. In addition, it is possible to return to the commandmode with the interface signal DTR or to immediately terminatethe connection.

8.5.3.4 ATS25=<value>

Fixing a value as DTR Ignore Timer

Fixing a value between 0 and 127seconds as "DTR Ignore Timer"means that the DTR signal from DTEis not checked by the CITAM for thistime span after the connection hasbeen established. This way a con-nection that has just been estab-lished cannot be terminated immedi-ately by the terminal equipment. Inorder to save this value permanentlyyou need a CITAM equipped with a 2kbit EEPROM (CITAM module C4,C5, C6, C6M, C7). Additionally youhave to save the ATS25-value byentering the command AT&W. Ifthese two preconditions are not ful-filled the ATS25-value is set back to0 when a RESET is performed.

INBAND Communication 9

9 INBAND Communication - 1

9 INBAND Communication

INBAND communication is only possible between Control-ware devices and takes place in the B channel.

9.1 ActivationThe integrated INBAND option serves to exchange informa-

tion between two Controlware devices which are interconnected.

After a connection set-up, the CITAM attempts to communicatewith the opposite terminal via the switched B channel.

With this data exchange, various types of information aretransmitted, both for a normal connection set-up and for a re-mote configuration.Several options are available to set the INBAND function. Thefirst option serves for the activation of INBAND.

The option “INBAND” can only be activated forboth ports together.

♦ If the INBAND function is switched off, the port selection isperformed with the information which is provided by theISDN network (EAZ in the 1TR6, resp MSN in the DSS1).

A remote configuration is only possible if the op-tion INBAND has been activated.

♦ If the INBAND communication is set to “BUS”, the ISDN in-formation received first (EAZ or “local number”) is checkedto determine whether it applies for a port. The call is onlyaccepted in this case.

During the bus operation, it has to be ensuredthat the INBAND function is set to “BUS”.



Fig. 9-1: Configuration for INBAND communication via the front panel

With the command SET INBAND xx, the INBAND communica-tion is activated (xx = ON), deactivated (xx = OFF) or configured(xx = BUS) for the bus operation.

Fig. 9-2: Configuration for INBAND communication via theWindow System

The functions PASSWORD, AuotBaud, CALLSUB,CALLBACK, BACKDELAY, and Remote are only available inthe INBAND mode.

9.2 Password


9.2 PasswordIf the option INBAND communication is activated between two

Controlware devices, it is possible to protect the password for theISDN connections. This password may be valid for all ISDN con-nections or only for connections which are set up for a remoteconfiguration (see chapter 9.4).

The password which is set to check the admissibility of an in-coming call always consists of 10 characters. No blanks areallowed in the password. A preset password consists of the last10 digits of the internal hardware serial number of the CITAM.

There is a hardware default password which consists of thelast 10 digits of the internal serial number of the CITAM.

9.2.1 Configuration of the Password ProtectionThe setting procedures for the various operation modes are

explained in detail in section 7.31.

1st Option: ... for remote configuration only

If the password is only valid for the remote configuration, thestored password is compared with the received passwordwhen receiving a connection request for a remote configura-tion. If the passwords match, the connection is set up and theconfiguration is performed. If the passwords do not match, thecombination is rejected with an error message. In order tostart a remote configuration, a password has to be enteredwhen using the connection command of the supervisor.In the case of the command-orientated supervisor, thepassword is part of the command line; in the case of theWindow System, it is a command entered on the“CONNECT” layer. When leaving the password menu, thedialing procedure is directly initiated. When going furtherback to the port selection menu instead, the set passwordwhich is sent with a call is reset to “0000000000”. Thesame presetting is made for the command-orientated su-pervisor, if no further characters follow “@” .



2nd Option: ... for all ISDN connections

If the password is valid for all ISDN connections, a pass-word is also exchanged for normal port connections.

The password is sent with every connection re-quest and is checked for every incoming call.

This means that two CITAMs must have the same pass-word if they are to be interconnected. For a remote con-figuration, the password always has to be indicated,since the stored password is only sent automatically in thecase of conventional password connections.If the password check was successful, the connection is ac-cepted; otherwise, it is rejected with an error message. Inthe case of this configuration, all TAs are also rejectedwhich cannot support INBAND communication and there-fore are unable to send passwords.

9.2.2 Entering and Changing the PasswordThe setting procedures for the various operation modes are


With the option INBAND communication between two Control-ware devices, it is possible to protect the password for theISDN connections.

The entering procedure is performed according to the enteringof the call numbers. Uppercase and lowercase letters are dis-tinguished.



9.3 Automatic Rate Adaptation withINBANDThe setting procedures for the various operation modes are


With the INBAND communication, it is possible to adapt thetransmission rates of two interconnected CITAMs.

For the AutoBaud function, the following parameters are avail-able:

UPPER If this parameter is set, the rate informationreceived via INBAND is evaluated for an in-coming call. If the received rate informationequals the set rate, the connection is setup.

If the received speed information exceedsthe set speed, the CITAM adapts itself tothe higher rate and the connection is set up.

If the received rate information is lower thanthe set rate, an error message is returned atthe locally set rate, and the calling side thenhas to decide whether the connection is setup or not.

LOWER With this parameter, the connection is onlyset up at equal or lower rates. Otherwise,an error message is returned at the locallyset rate, and the calling side has to decidewhether the connection is set up or not.

UPPER&LOWER With this parameter, the CITAM adapts it-self to every rate.

OFF With the parameter “OFF”, the automaticrate adaptation is switched off.

If the CITAMs were configured with different rates, the connec-tion is not set up if the corresponding adaptation is not permit-ted at the remote terminal.



This function is only supported in the case of asynchronous data transmission, as a rate adapta-tion does not make sense for asynchronousDTEs.

Corresponding messages are displayed at the supervisor ter-minal for different modes (synchronous, asynchronous) orrates.

The option AutoBaud can be separately activatedfor every port.

In the case of automatic rate adaptation, INBAND (AutoBaud)principally has priority over BRC. A reciprocal disturbance isnot possible. BRC is only executed on the calling side - if acti-vated - if INBAND is deactivated or an INBAND communicationis not established.

If INBAND/AutoBaud is deactivated or an INBAND communi-cation is not established, it is nevertheless possible to adaptthe rate via BRC.

If the BRC is set to “OFF” for a calling CITAM or if a rate is se-lected which is not defined in the ISDN protocol, the calledCITAM accepts the call without adaptation for BRC “OFF”. IfBRC “LOWER”, “UPPER” or “UPPER/LOWER” was selectedfor the called CITAM, the called CITAM automatically adapts it-self to a rate of 64,000 baud.The following table provides an overview on the rate adaptationin the INBAND mode, resp in the case of BRC.

setting of the called CITAM to64,000 baud



9.4 Remote Configuration withINBANDThe setting procedures for the various operation modes are


A further option provided by the INBAND communication is theremote configuration of a remote CITAM.

In order to configure a device on the remote side, a remoteconfiguration call (remote call) has to be sent. This remote calltransmits a password which is checked on the called side.

If the password matches, the connection is set up and a con-figuration is possible. Otherwise, the connection request is re-jected.

A remote call can only be made from a supervisor terminal (notvia front panel operation), i.e. only C1 CITAMs or C2 CITAMsare able to send remote calls. From software revision 2.10 on-wards, however, a remote configuration is possible with allhardware versions.

If a remote configuration call was successfully set up, thecalled CITAM answers with its prompt. For an unambiguousidentification, however, the characters “>>” are displayed con-versely (“<<”).

If the status of the port is now retrieved with the command“SHOW PORT n”, which is selected by the remote configura-tion, a message is displayed, which may read, as follows:

9.4 Remote Configuration with INBAND


Fig. 9-3: Query of the port status with the command “SHOW PORT n”in the remote configuration



9.5 INBAND CallbackThe setting procedures for the various operation modes are


With this INBAND function, the CITAM can request a callback,e.g. to cause charges for large data volumes to arise at specificplaces. In this case, only the charge for transmitting the call-back request arises.

For this option, the following parameters can be selected:

No/ignore No callbacks are requested at a connectionset-up.Incoming callback requests are ignored andare rejected with an error message on thecalling side.

No/accept No callbacks are requested at a connectionset-up. Incoming callback requests are ac-cepted and executed.

Yes/ignore The information for a callback request issent at a connection set-up.Incoming callback requests are ignored andrejected with an error message on the call-ing side.

Yes/accept The information for a callback request issent at a connection set-up.Incoming callback requests are acceptedand executed.

If a “local number“ was defined, up to SW-rel.4.03 this call number is sent in the D channel(set-up) and in INBAND.

9.5 INBAND Callback


Furthermore, it is possible to define a callback delay in order toinform the opposite terminal at the callback request how long itis to wait until the callback is started.

The input area ranges from 0 to 255 seconds.

The setting procedures for the various operation modes for thisoption are explained in detail in section 7.26.

Group Hunting Configuration 10

10 Group Hunting Configuration - 1

10 Group HuntingConfiguration

To configure the CITAM for group hunting (no TEI default,several ports with identical call number), set the subaddressrotary switch to "0" (TEI=Terminal Endpoint Identifier).Please note that the CITAM cannot be operated at a commonS0-access line with this configuration but only at access linesgenerated for group hunting.

Fig. 10-1: Port overview for group hunting

Set the subaddress rotary switch to a position between 1 and 8if the CITAM is to be operated at a common port again.

By setting the subaddress rotary switch to "0" (configuring theCITAM for group hunting) the allocation of port subaddressesis performed internally.

As long as DIP switch configuration is active and the portshave been configured upon a RESET via the settings of thesubaddress rotary switch DIP switches, subaddress 1 is as-signed to port 1 and subaddress 2 is assigned to port 2.

This default can be modified at any time via front panel or su-pervisor but not by means of the subaddress rotary switchwhich is set to "0" for group hunting configuration.

Leased Line Connections 11

11 Leased Line Connections - 1

11 Leased Line Connections

11.1 General DescriptionIn addition to the normal dial-up lines (dialing and semiper-

manent dialing), the CITAM supports three types of leased lineconnections: Digital 64S, Digital TS01, Digital TS02 (see ap-pendix).

For leased line connections, the subaddress rotary switch hasto be set to “2” and the DIP switch S1-2 to “ON”. With this set-ting, the DIP switches are permanently activated.

All other settings (e.g. rate and bit rate adaptation) are to be setaccording to the standard procedure. It should be ensured thatall settings are only made via DIP switches.

The CITAM cannot be operated at a bus, i.e. only one CITAM maybe operated per access. In the case of this connection type, theCITAM uses the D channel for the port selection at the connectionset-up; no function control protocol, however, is transmitted via theD channel. If the transmission line breaks down, LAYER 1 has tobe disconnected by the NTs of the network provider, so that theCITAM is able to recognize the failure and can set up the connec-tion again if the transmission line is available again.

These settings are also valid for monopoly connections!

Fig.11-1: Minimum configuration CITAM for leased line connections

All further settings, such as the baud rate, are configured asusual via the DIP switches S1 and S2.

LMU-1 Support

From SW rel. 4.15 on the CITAM 128 (with 128 kbps leasedline connection) supports the LMU-1 from Controlware which isespecially designed for ISDN line monitoring. If certain errors,e.g. octet slips, occur on the leased line the LMU-1 sets its Csignal to "low" forcing the CITAM 128 to resynchronize the Bchannels. If an LMU-1 is operated with a CITAM 128 on aleased line select the default DIP-switch setting shown in figure11-1.

In case you do not operate an LMU-1 with CITAM 128 selectthe settings shown in figure 11-2.

Fig. 11-4: Configuration CITAM 128, SW 4.15, without LMU



11.3 Possible Problems with LeasedLine ConnectionsSince the CITAM can only check the functioning of the line

via LAYER 1, it has to be ensured that the LAYER 1 is sup-ported correctly by the NTs of the Telekom.

“MixMode" replaces the parameter “S0FV” in all menu locationsin the CITAM configuration menus. With “MixMode”, a port canbe switched into the leased line mode, similarly to “S0FM”, butonly for this port. The second port (if available) can be oper-ated in parallel in the dial-up line mode and uses the D channelprotocol.

If both ports are to be operated in the leased line mode, thesetting “S0FM” has to be selected via the DIP switches.

In the case of the setting “MixMode” ist has to benoted that only the parameters transmissionrate (cf. section 7.8) and operation mode (cf.section 7.2) may be configured in deviation fromthe default setting. In addition, it should be notedthat the parameter for activation/deactivation ofthe interface procedures (cf. section 7.12) is setto “ignore”.

If the DIP switch S1-2 is set to “ON” and the subaddress rotaryswitch S3 is set to position 1, the “MixMode” is the default set-ting for the port with the active DIP switches.

If the DIP switch S1-2 is set to “ON” and the rotary switch S3 isset to position 2, the setting for both ports is “S0FM”, regardlessof the DIP switch status.

Test Possibilities for Data Transmission 12

12 Test Possibilities for Data Transmission - 1

12 Test Possibilities for Data

TransmissionThe CITAM allows to switch loops in order to test the data

transmission. In the modes Front Panel Control, Auto Dial,V.25bis or Hayes AT, a loop can be initiated via the interfacesignals PS2 and PS3. Here, the three different loops are pos-sible: LOCAL LOOP, REMOTE LOOP, and LOCAL LOOPBACK.

A perfect functioning of the loop switch LOCALLOOP is only ensured if layer 1 is activated.

12 Test Possibilities for Data Transmission


12.1 V.24 Interface12.1.1 LOCAL LOOP

DTE CITAM ISDN

Signal Local

Fig. 12-1: Local loop

The loop switch LOCAL LOOP is initiated via the interfacesignal PS3 (pin 18 on the V.24 interface of the I/O module oron the CEPT interface A14 for port 1 and B21 for port 2). Thesetting of the PS3 to “ON” sends the transmitted data back tothe DTE.

The cable to the DTE, the interface drivers on the I/O module,and the bit rate adaptation component ITAC in the CITAM aretested. The test is possible without ISDN connection.

The loop switch LOCAL LOOP is deleted again if the PS3 in-terface signal is set to “OFF”.

If a LOCAL LOOP is requested during a connec-tion, the connection is terminated if the signalPS3 impends for longer than one minute and ifthe transmission rate does not exceed 48 kbps.

12.1 V.24 Interface


12.1.2 REMOTE LOOP

DTE DTECITAM CITAMISDN

Signal Local Remote

Fig. 12-2: Remote Loop

The loop control REMOTE LOOP is initiated via the inter-face signal PS2 (pin 21 on the V.24 interface of the I/O moduleor on the CEPT interface A18 for port 1 and B20 for port 2) andis only possible for established connections.

Setting PS2 to “ON” sends the transmitted data back to theDTE via the remote terminal. The control of this loop switch isnot supported by the ISDN.

The switching of the REMOTE LOOP is made possible byControlware ISDN products by utilizing the X bits in the dataframe of the B channel,i.e. the parameter “XX bits” has to beset to “active” for both CITAMs.

This means at the same time that only Controlware ISDNproducts can mutually initiate REMOTE LOOPs. Presently, theTAXI system represents the only exception from the rule, as itdoes not support this functionality.

To avoid problems with other terminal adapters, the CITAM al-lows the suppression of the evaluation in the submenu LAYER3 CONF XX-B, which is the standard procedure.

The cable to the local DTE, the local device itself, the trans-mission line, and the remote terminal, excluding the interfacedrivers, are tested.

A further limitation, which is caused by the utilization of the Xbits (see section 7.28), is the fact that a REMOTE LOOP isonly possible up to 48 kbps. The REMOTE LOOP is deleted ifthe interface signal PS2 is set to “OFF” or if the connection isterminated.



12.1.3 LOCAL LOOP BACK


Signal Local RemoteSignal

Fig. 12-3: Local Loop Back

The loop switch LOCAL LOOP BACK is initiated by the si-multaneous activation of the interface signals PS2 and PS3(pin 18 and 21 on the V.24 interface or A14 and A18 for port 1and B21 and B20 for port 2 on the CEPT interface) and is onlypossible in the case of an established connection.

By setting the interface signals PS2 and PS3 to “ON”, thetransmitted data are sent back to the remote terminal.

The entire remote unit, consisting of DTE, cables, the CITAMitself, as well as the ISDN connection are tested. The LOCALLOOP BACK is deleted if the interface signals PS2 and PS3are set to “OFF”.

12.2 X.21 Interface


12.2 X.21 InterfaceIn the X.21 mode, only the two loop switches LOCAL LOOP

and REMOTE LOOP are available. In addition, they are not di-rectly switched with an interface signal in this mode, but by theinteraction of the interface signal C and the data sent by theDTE.

A loop is activated by the setting “C=OFF” and a specific bit pat-tern which has to be transmitted by the DTE. If the DTE C nowswitches to “ON” again, the data transmitted hereafter are corre-spondingly lead to the switched loop. The test is deactivated ifthe DTE sets the interface signal to “C=OFF” again.

12.3 ISDN Connection TestThe setting procedures for the various operation modes are


With this function, a connection test can be carried out. Withthis connection test, it is checked whether the opposite terminalcan be accessed, and whether the subaddresses, modes, andrates match.

If these parameters match, this is confirmed with the message“ISDN-Check passed, PORT n”. If an error is detected, this isindicated with the message “ISDN check failed, PORT n“, aswell as with a possible INBAND and/or ISDN error message.

The command ITEST is used in accordance with the commandPORT and can therefore be applied for stored or directly en-tered call numbers. This function is only available if INBAND isset to “ON“.

After the test, the connection is automatically terminated.

12.4 ISDN Loop Test with INBANDThe configuration procedures for the various operation

modes are explained in detail in section 7.46.

With this command, the opposite terminal is informed that atest loop (loop) is to be initiated. The connection is set up ac-cording to the standard procedure, but all sent data are re-turned by the opposite terminal.

By doing so, the transmission line can be tested.

The test loop remains active until the connection is terminatedagain. The message “ISDN-Loop requested from PORT n” issent for the port which requests the loop. For the port wherethe loop is switched, the error message “ISDN-Loop switchedat PORT n” is sent.

12.5 ISDN Loop Test with Subaddress


12.5 ISDN Loop Test with SubaddressThe configuration procedures for the various operation

modes are explained in detail in section 7.46.

In order to automatically test the availability of the ISDN remoteterminal together with a data transmission, a loop request canalso be marked by the call number. For this, the EAZ 9 is used.

Three different configurations are possible when using this EAZ.

Configuration 1: Calling device: no INBAND or INBAND setto “OFF”.

Called device (CITAM): INBAND set to“OFF”.

The called device identifies the EAZ 9.

It treats the EAZ like a global call (EAZ 0). Itconnects a free port (port 1 has the highestpriority) and switches a test loop to this port.The interface has to accept this call; other-wise the call is rejected.

The test loop remains active until the con-nection is terminated again.

Configuration 2: Calling device: no INBAND or INBAND setto “OFF”.

Called device (CITAM): INBAND set to “ON”.

The called device forwards the call. After atimeout, the INBAND procedure is deacti-vated and EAZ 9 is identified.

The CITAM treats the EAZ like a global call(EAZ 0), connects a free port (port 1 hasthe highest priority), and switches a testloop to this port. The interface has to acceptthis call; otherwise the call is rejected. Thetest loop remains active until the connectionis terminated again.

Configuration 3: Calling device: INBAND set to “ON”. Calleddevice (CITAM): INBAND set to “ON.

The EAZ 9 is rejected. To switch a looptest, the ISDN loop test has to be used withINBAND (see sections 12.4 and 7.46).

13 CITAM-Rack

Fig. 13-1: The CITAM-Rack supplied with 14 CITAMs and fancard

In order to facilitate the installation of a larger number ofCITAMs at one location, Controlware has developed a specialrack for the CITAM, the CITAM-Rack.The CITAM-Rack does not only allow a more compactarrangement of the devices, but also a (just as advantageous)configuration option by means of a single terminal.

Please check under section 13.1 whether yourCITAM plug-in version(s) is (are) suited for theinstallation in the CITAM-Rack.

13 CITAM-Rack

13 CITAM-Rack - 2

A CITAM-Rack is equipped with 15 slots. A maximum numberof 13 slots can be used for application CITAMs. A freelyselectable slot (e.g. slot 15) serves to accommodate a specialI/0 module, the CSC module, which is used to connect thesupervisor terminal.

Furthermore, it it is possible to connect up to 75 CITAMs witheach other via the SUPCON desktop device and to control alldevices centrally via a terminal. It should be noted that everyslot address in the system may only be allocated once!

The operation of the CITAM-Rack implies that only one CITAMat a time communicates actively with the terminal. During thisinterval, all other CITAMs cannot be accessed by the terminaland all messages occurring there are lost. Therefore, thesupervisor terminal should principally be understood as aconfiguration terminal. Simultaneously, it constitutes amonitoring terminal for the active CITAM only.

13.1 Limitations for the Operation of CITAMPlug-in Modules in the Rack

13 CITAM-Rack - 3

Power Supply

With the CITAM-Rack you have the choice between two differentpower supply units:♦ A power supply unit by Vero which can be operated at 110 V

as well as 220 V. For the operation of this card an additionalfan card is necessary. For CITAM plug-in modules thisleaves a maximum of 14 slots resp. 13 slots for operationwith a CSC module.Additionlly it is possible to add a second redundant Vero-power supplytogether with a second fan card. In case ofmalfunction this second module can take over the supply ofthe rack. In this configuration 11 slots (resp. 10 with CSCmodule) are available for CITAM plug-in modules.

♦ A power supply unit by Elektrosil which can be operated at220V only. An additional fan card is not necessary.

13.1 Limitations for the Operation ofCITAM Plug-in Modules in the RackNot all CITAM plug-in modules which are operated in the

adapter case as desktop devices are designed for the use inthe CITAM-Rack. If you would like to install plug-in modules ofyour desktop device in a CITAM-Rack, please observe thefollowing limitations.

13.1.1 CITAM C0 and C4The CITAM C0 and C4 plug-in modules are principally not

suited for the installation in the CITAM-Rack. If this version,which is not equipped with a supervisor, is neverthelessinstalled in a CITAM-Rack, disturbances of the entire bus mayoccur.

13.1.2 CITAM C1, C2, C2M, C3,HW Revision 1.2/1.3CITAM C1, C.2, C2M, and C3 plug-in modules are

equipped with the internal component U4 (EPLD) and aresuited for the operation in the CITAM-Rack, because theyprovide the option to be configured via a supervisor.

For individual special customer applications,plug-in modules were delivered withoutsupervisor function. These versions are notsuited for the operation in the CITAM-Rack.

13.1.3 CITAM C1, C2, C2M, C.3, C5, C6, C6M, C7 HWRevision 1.4CITAM C1, C2, C2M, C.3, C5, C6, C6M and C7 plug-in

modules of the HW Revision 1.4 are generally suited for theoperation in the CITAM-Rack, as they provide all supervisorfunctions.

13.2 Configuration and Activation

13 CITAM-Rack - 5

13.2 Configuration and ActivationEvery plug-in module used in the CITAM-Rack has to be

configured as a rack module. To do this, the DIP switch S2-8 isset to “ON”.

Allocation of Slot Addresses

This slot address can be freely selected from 1 to 15 or – in thecase of several CITAMs connected with each other via aSUPCON –from 1 to 75.

For reasons of clarity, it is recommended, however, to observea certain numeric sequence. The most sensible method is to“count” all connected CITAMs, starting with “1” for the firstCITAM and continuing with every connected CITAM.

Fig. 13-3: Allocation of slot addresses via the front panel

With the command SET DEBUG SLOT [ee], a slot address [ee =1-15 (75)] can be allocated.No slot addresses can be allocated via the Window System.

13 CITAM-Rack

13 CITAM-Rack - 6

Selection of a Device for the Configuration

The selection of a CITAM to enter commands is only possiblewith the command SYS n of the Command Supervisor. Theport LED of the active device in slot n blinks.

In order to ensure a perfect functioning of the CITAM, rack respof all connected CITAM-Racks, a slot address has to beallocated for every CITAM.

13.3 CITAM as ISDN Extension

13 CITAM-Rack - 7

13.3 CITAM as ISDN ExtensionOne of the fifteen available slots, in our example slot 15 ,

serves to accommodate a special I/0 module, the CSCmodule, which is responsible for the connection of thesupervisor terminal.

In this case, it is also possible to plug in a further (14th)CITAM, which, however, can here only be used for the remoteconfiguration of the interconnected CITAM-Rack.

To do this, the CITAM has to be set to 9.6 kbps asynchronous(8N1) and Interface = ignore. In this case, the supervisor cableis not connected to the terminal, but to the V.24 access of theCSC module.

The CITAM now serves as an ISDN extension for a terminalwhich can be connected to the rack via a CITAM (see fig.).

Fig. 13-4: CITAM as ISDN extension

13 CITAM-Rack

13 CITAM-Rack - 8

13.4 Interconnection of Several CITAM-RacksSeveral CITAM-Racks can be interconnected via a

SUPCON. The slot for the CSC module and the control CITAMare not predetermined. All 15 rack slots are selectable.

Related products, such as the SIMON or the PRIMUS ofControlware, can be operated simultaneously in the CITAM-Rack. It has to observed, however, that these devices cannotbe configured via a supervisor terminal.

If several CITAM-Racks are switched to one terminal viaSUPCON and the terminal is switched on after the racks, theCITAMs cannot be addressed via the terminal.

Upon the attempt to enter a command, only smearedcharacters are displayed on the screen.

The CITAM can be activated by initiating a RESET (so that theterminal is identified) or with the command “SYS n” via theCommand Supervisor, i.e. with a slot number of an alreadyavailable CITAM.

The echo of this command is again constituted by smearedcharacters, but the selected CITAM is activated upon <CR>.

During mixed operation it is to be observedthat the permitted maximum load of the powersupply is not exceeded.

14 SW Versions for North

America and CUSTOMNETAustralia

In North America, resp in the CUSTOMNET ISDN network inAustralia either the AT&T Central Office Switch (CO Switch) or theNorthern Telecom DS-100 CO Switch are used.

Since these switches have different features, a separate con-figuration of the CITAM is required. All necessary settings toselect the corresponding CO Switch can be made via the frontpanel, Command Supervisor or Window System, as well as bymeans of Hayes AT commands.

Please note that the CITAM will automaticallyexecute a RESET after changing the switches,resp the SPID number. The LOCALCHECK has to be activated.

Upon activating the function CITAM 1 in the Window System,the following information is recorded.

14.1 Entering the SPID Numbers andSwitchesThe setting procedures for the various operation modes are


The SPID numbers are allocated by the network provider. Inorder to simplify the configuration of SPID number(s) (serviceprofile identifier) and switches, an input menu was included inthe front panel and supervisor. If the CITAM is only equippedwith a single port, only one SPID number can be entered ac-cordingly.

With the exception of the switch AT&T 5E6 (no SPID num-bers), two SPID numbers are to be configured for a double-portCITAM. The call number storage locations 7 and 8 are re-served for the SPID numbers, i.e. only 6 storage locations areavailable for call numbers.

14.2 Configuration of an AT&T 5ESS COSwitch


14.2 Configuration of an AT&T 5ESSCO Switch

14.2.1 Switch Software 5E8 or Later Versions (e.g.5E9)In the case of this switch it is necessary to configure the

CITAM for the SPID number assigned by the telephone com-pany (service profile identifier). This SPID number is enteredlike all other numbers in the call number storage menu of theCITAM.

On storage locations T.07/T.08, the SPID numbers are enteredas assigned for the access.

After storing a SPID number, the CITAM has to be reset with aRESET to enable it to send this new SPID number to the ISDNnetwork for initialization.

It is to be ensured that the number is not deletedor changed as long as the CITAM is operated atthis access.

After entering the SPID number, the setting for the corre-sponding switch and its software still has to be performed. Thiscan be done either via the front panel or the command line ofthe supervisor (see section 7.44).

The CITAM then executes a RESET to take over the configu-ration for the ISDN software.

14.2.2 Switch software 5E7 or Older Versions (e.g.5E6, 5E5)No SPID number is required for this switch. The corre-

sponding CO Switch, as well as its software can be configuredvia the front panel or the supervisor command line (see section7.44).




14.3 Configuration for a NorthernTelecom DMS-100 CO SwitchFor this purpose, the telephone company will supply one or

two numbers for the access, the so-called “Service ProfileIdentifier” (SPID). The Northern Telecom DMS-100 CO Switchrequires a SPID number for every B channel of the access. Ifonly one B channel was ordered for the operation of a single-port CITAM, only one SPID number is provided. If both Bchannels are to be used, two SPID numbers are assigned.

Like all other numbers of the CITAM, the SPID numbers haveto be entered in the call number menu of the CITAM. The stor-age locations T.07 and T.08 are reserved for this purpose. Ifonly one SPID number is provided, it is stored on storage loca-tion T.07.

If both B channels are to be used, the SPID number has to bestored on storage location T.07 for port 1, and the SPID num-ber is stored on T.08 for port 2. Subsequently, a RESET has tobe executed at the CITAM to enable it to send this/these newSPID number(s) to the ISDN network for initialization. It has tobe ensured that this/these number(s) are not deleted orchanged as long as the CITAM is operated at this access.

Set the corresponding switch via the front panel, the CommandSupervisor or the Window System (see section 7.44).


14.4 Configuration of another CO Switch withthe NI1 Software


14.4 Configuration of another COSwitch with the NI1 SoftwareThe configuration for all other CO Switches with the national

ISDN-1 software is performed as in the case of the AT&T5ESS CO Switch with software 5E8 or later versions. The cor-responding setting, however, has to be made when selectingthe switch (see section 7.44).


14.5 Trouble Shooting in this SWVersionThe supervisor port provides efficient functions to support

the trouble shooting. This includes information on initializingthe SPID number and error codes, which are provided by theISDN network.This help function is only provided by CITAMs with supervisorports.

The following table shows a short overview on the informationor error messages which may occur. All other messages canbe found in the list “Messages according to ETS 300 102 -1/A2.”



Supervisor Port Message Possible Reason

SPID init successful This message appears within 30sec. after a RESET or afterswitching on the CITAM if a SPIDnumber is required for the access,this was stored in the CITAM, andthe initialization to the ISDN net-work was successful.

SPID init failed This message appears if the ini-tialization to the ISDN networkwas not successful.

Reason 10:

normal call clearing:

This message appears if a con-nection has been initiated. In thecase of a Northern TelecomDMS-100 switch, this messagemay also mean that an invalidcall number was dialed.

Reason 14:call rejected

This error code may be sent byan AT&T 5ESS switch if the SPIDnumber was not configured cor-rectly.

Reason1C::invalid number format

This error code may be sent byan AT&T 5ESS switch if an inva-lid call number was dialed.

Reason 22:no channel available

This error code may be sent byan AT&T 5ESS or Northern Tele-com DMS-100 switch if an invalidcall number was dialed.

Reason 32: requestedfacility not subscribed

This error code may be sent by aNorthern Telecom switch if theinitialization of the SPID numberto the ISDN network was notsuccessful and a connection set-up was attempted.

A 3 Software-Upgrade

Appendix - 9

A 3 Software-UpgradeBefore upgrading the CITAM software, it is recommended

to reset the internally stored options to default values in orderto obtain an unambiguous basic condition for any additionalmodifications to the configuration.

To do this, the CITAM‘s internal EEPROM storing all optionsfor the event of power failure must be deleted.

To delete the EEPROM, proceed as follows:♦ Press one of the green buttons and keep it pressed.


♦ Now, the CITAM performs a reset.

♦ Release the green button as soon as the CITAM starts therunning display "CITAM 1 ...".

♦ Then, the CITAM identifies itself and displays the respectivesoftware release:Module Cx - SSNR: CW xxx xxx xxx xxx


ISDN-Country Ver.: country, version, revision

♦ Subsequently, the CITAM performs testing of its internalhardware modules. Press the two green front panel buttonsas follows (see table):

Module Display Meaning/buttons

8930 ok Only this display indicates smooth opera-tion.

8981 ok/bad This display depends on the fact whetherthe module is present or not.

93x6 At this very moment, but not before, pressboth green buttons simultaneously andkeep them pressed until the next displayappears.

clr Confirms that the internal EEPROM wasdeleted. Now, you can release the twobuttons.

♦ Repeat this procedure, if required.

Appendix

Appendix - 10

♦ Finally, press the RESET button again briefly.

♦ Now, the CITAM is prepared to work with the new softwarerelease.

♦ In the case of a CITAM which is operated via supervisor areset can also be performed with the "RESET DEFAULT"command.

A 6.2 Inband communication messages

Code/message

02 "invalid message format"

A message format has been modified and is no longer com-patible. Or a message has been modified due to a transmis-sion error. In case of a transmission error, the message is pos-sibly ignored as commands are repeated.

51 "invalid password"

No match is found for the password; for this reason, the con-nection request is rejected.

52 " invalid OAD"

The result of the calling unit number check is negative; for thisreason, the connection request is rejected.

54 "invalid subaddress"

The subaddress transmitted via inband is rejected.

55 "different baudrate"

The ports are operated with different transmission speeds;still, it depends on the configuration whether the call is suc-cessful or rejected.

56 "invalid mode"

The ports are operated with different modes (asynchronous,synchronous); for this reason, the connection request is re-jected.

57 "called port busy"

The called port is already engaged.

62 "port configured to deny access"

The port is configured to not accept the connection request.

63 "remote control active"

The CITAM is already configured from a remote location.

70 "callback not allowed"

A request for callback is rejected.

A 6 Cause codes

Appendix - 17

A 6.3 Cause codes accoding to ETS 300 102 - 1/A2

Cause code meaning/explanation(hexadecimal)

01 "unallocated (unassigned) number"

This cause indicates that the destination requested by the call-ing user cannot be reached because, although the number isin a valid format, it is not currently assigned (allocated).

02 "no route to specified transit network"

This cause indicates that the equipment sending this causehas received a request to route the call through a particulartransit network which it does not recognize. The equipmentsending this cause does not recognize the transit network ei-ther because the transit network does not exist or because thatparticular transit network, while it does exist, does not servicethe equipment which is sending this cause.

This cause is supported on a network-dependent basis.03 "no route to destination"

This cause indicates that the called user cannot bereached because the network through which the call hasbeen routed does not serve the destination desired.

This cause is supported on a network-dependent basis.06 "channel unacceptable"

This cause indicates the channel most recently identifiedis not acceptable to the sending entity for use in this call.

07 "call awarded and being delivered in an establishedchannel"

This cause indicates that the user has been awarded theincoming call, and that the incoming call is being con-nected to a channel already established to that user forsimilar calls (e. g. packet-mode X.25 virtual calls).

10 "normal call clearing"

This cause indicates that the call is being cleared be-cause one of the users involved in the call has requestedthat the call be cleared. Under normal situations, thesource of this cause is not the network.

Appendix

Appendix - 18

Cause code meaning/explanation (ETS 300 102 - 1/A2)

(hexadecimal)

11 "user busy"

This cause is used when the called user has indicatedthe inability to accept another call. It is noted that theuser equipment is compatible with the call.

12 "no user responding"

This cause is used when a user does not respond to acall establishment message with either an alerting orconnect indication within the prescribed period of timeallocated (defined in ETS 300 102-1 by the expiry of ei-ther timer T303 or T310).

13 "no answer from user (user alerted)"

This cause is used when a user has provided an alertingindication but has not provided a connect indicationwithin a prescribed period of time.

NOTE: This cause is not necessarily generated byETS 300 102-1 procedures but may be generated byinternal network timers.

15 "call rejected"

This cause indicates that the equipment sending thiscause does not wish to accept this call, although it couldhave accepted the call because the equipment sendingthis cause is neither busy nor incompatible.

16 "number changed"

This cause is returned to a calling user when the calledparty number indicated by the calling user is no longerassigned. The new called party number may optionallybe included in the diagnostic field. If a network does notsupport this capability, cause #1 unallocated(unassigned) number shall be used.

1A "non-selected user clearing"

This cause indicates that the user has not been awardedthe incoming call.

A 6 Cause codes

Appendix - 19


(hexadecimal)

1B "destination out of order"

This cause indicates that the destination indicated by the usercannot be reached because the interface to the destination isnot functioning correctly. The term not functioning correctlyindicates that a signalling message was unable to be deliv-ered to the remote user; e. g. a physical layer or data linklayer failure at the remote user, user equipment off-line, etc. .

1C "invalid format (address incomplete)"

This cause indicates that the called user cannot be reachedbecause the called party number is not in a valid format or isnot complete.

1D "facility rejected"

This cause is returned when a facility requested by theuser cannot be provided by the network.

1E "response to status enquiry"

This cause is included in the STATUS message whenthe reason for generating the STATUS message was theprior receipt of a STATUS ENQUIRY message.

1F "normal, unspecified"

This cause is used to report a normal event only whenno other cause in the normal class applies.

22 "no circuit/channel available"

This cause indicates that there is no appropriate cir-cuit/channel presently available to handle the call.

26 "network out of order"

This cause indicates that the network is not functioning cor-rectly and that the condition is likely to last a relatively long pe-riod of time; e. g. immediately re-attempting the call is not likelyto be successful.

29 "temporary failure"

This cause indicates that the network is not functioningcorrectly and that the condition is not likely to last a longperiod of time; e. g. the user may wish to try another callattempt almost immediately.

Appendix

Appendix - 20

2A "switching equipment congestion"

This cause indicates that the switching equipment gene-rating this cause is experiencing a period of high traffic.

2B "access information discarded"

This cause indicates that the network could not deliveraccess information to the remote user as requested;i. e. a user-to-user information, low layer compatibility,high layer compatibility, or subaddress as indicated inthe diagnostic.

(Cause #43) It is noted that the particular type of accessinformation discarded is optionally included in the diag-nostic.

2C "requested circuit/channel not available"

This cause is returned when the circuit or channel indi-cated by the requesting entity cannot be provided by theother side of the interface.

2F "resource unavailable, unspecified"

This cause is used to report a resource unavailableevent only when no other cause in the resource unavail-able class applies.

31 "quality of service not available"

This cause indicates that one equipment has requestedan unrestricted bearer service but that the equipmentsending this cause only supports the restricted version ofthe requested bearer capability.

4F "service or option not implemented, unspecified"

This cause is used to report a service or option not im-plemented event only when no other cause in the serv-ice or option not implemented class applies.

51 "invalid call reference value"

This cause indicates that the equipment sending thiscause has received a message with a call referencewhich is not currently in use on the user-network inter-face.

Appendix

Appendix - 22


(hexadecimal)

52 "identified channel does not exist"

This cause indicates that the equipment sending this causehas received a request to use a channel not activated on theinterface for a call. For example, if a user has subscribed tothose channels on a primary rate interface numbered from1 to 12 and the user equipment or the network attempts touse channels 13 through 23, this cause is generated.

53 "a suspended call exists, but this call identity does not"

This cause indicates that a call resume has been at-tempted with a call identity which differs from that in usefor any presently suspended call(s).

54 "call identity in use"

This cause indicates that the network has received a callsuspend request. The call suspend request contained acall identity (including the null call identity) which is al-ready in use for a suspended call within the domain ofinterfaces over which the call might be resumed.

55 "no call suspended"

This cause indicates at the network has received a callresume request. The call resume request contained acall identity information element which presently doesnot indicate any suspended call within the domain of in-terfaces over which calls may be resumed.

56 "call having the requested call identity has been cleared"

This cause indicates that the network has received a call re-sume request. The call resume request contained a call iden-tity information element which once indicated a suspendedcall; however, that suspended call was cleared while sus-pended (either by network timeout or by the remote user).

58 "incompatible destination"

This cause indicates that the equipment sending thiscause has received a request to establish a call whichhas low layer compatibility, high layer compatibility, orother compatibility attributes (e. g. data rate which cannot be accommodated).

Appendix - 25

A 7 Trouble shootingState/error Reason/action

Yellow SO displayflashing

Indicates that the device is connected to theISDN socket; however, layer 1 is not acti-vated. This display does not imply that the theconnection has been performed correctly; butonly indicates the network voltage. This func-tion depends on the CITAM hardware, it is notsupported in Release 1.3).

Upon connection establishment or upon anincoming call, the yellow S0 LED must be oncontinuously.

Yellow S0 display off Dial-up connection: normal or ISDN cable isnot plugged in the ISDN socket: insert cable.Dedicated connection: the CITAM is not ableto activate layer 1. Check ISDN socket forcorrect connection or contact common carrier.

Green port displays off Dial-up connection: no connection estab-lished. Port-LEDs are activated upon P1/P2connection.Dedicated connection: the CITAM is not ableto establish a connection. In case of the 1-portversion, P1 must be active; in case of the2-port version, P1 and P2 must be active.Check whether the display is on.

Green port displaysP1/P2 flash quickly

Indicates an incoming call for the corre-sponding port; the interface procedure ac-cepts this call with delay.

Green port display P1 orP2 flashes slowly

The CITAM performs a remote configurationor is configured from a remote location.

A connection is estab-lished and the ISDN/-S0FV/SOFVM displayflashes

For the CITAM, a baud rate <56 kbps is set;however, the connection does not synchro-nize. Check whether the TAs are configuredto the same speed and mode.

It is not possible to editthe call number or modifya configuration parametervia the front panel.

The menus have been selected in "Show" mode.In this mode, however, you can only view but notmodify parameters or call numbers.Press the [SEL] key in the "Show" menu andkeep it pressed for 3 seconds. As soon as"Chng" is displayed, select the respectivemenu items via the [ENT] key.

Appendix

Appendix - 26

State/error Reason/action

A connection establishedvia front panel or super visoris cleared immediately.

On the CITAM, "lnterface" is set to "active"and the connection is cleared by the inter-face procedure. Set "Interface" to "ignore" ifthe connection is to be controlled exclusivelyvia front panel or supervisor.

It is not possible to establisha connection via front panel.

The display shows "→←".No call number is stored.Store call number.The connection request is rejected alongwith an error message. Compare the HEXerror code with the 1TR6 or CCITT errortables in correspondence with the ISDNprotocol and read the description (e.g. wrongcall number stored, for this reason errormessage "destination not obtainable").

Supervisor terminal cannotcommunicate with theCITAM.

In this case, a CITAM C0 version without su-pervisor option is used. The terminal configura-tion is incorrect. Check whether the terminal isset to 9.6 kbps, 8 data bits, no parity, 1 stop bit.

The window system is acti-vated and only control char-acters and discontinuoustexts are displayed on thescreen.

The connected terminal is not configured toVT100. Configure terminal correctly.The CITAM‘s window system cannot beused if no VT100 terminal is available.

The CITAM performs a re-set when you switch fromthe S0FV to Dial/Semi pa-rameter and vice versa.

Normal operation of the CITAM.To ensure that the CITAM is reset correctlyfor this application, a reset is generatedautomatically. This internally performed resetis equivalent to pressing the red button.

The CITAM has been con-figured to Autodialing andthe call criterion applies, butthe CITAM does not dial.

Check whether a call number is stored onthe specified storage location. If not, store acall number.

The configuration of theCITAM has been modifiedvia the DlP switches; how-ever, the CITAM does notreact to this modified con-figuration.

Check whether the DIP switch option is setto "active". If not, set to "active". As soon asa parameter is modified via the front panel,supervisor or interface procedure, theCITAM sets this option to "incactive".

A 7 Trouble shooting

Appendix - 27

State/error Reason/action

When displaying the in-ternal SSNR serial num-ber, the CITAM indicatesa failure.

Refers to a problem concerning the serialnumber chip. The reason for this problem liesin the fact that threshold values have beenmodified in the new chip production, and insoftware versions lower than 2.02, this problemhas not been solved.However, this does not affect by any means100% functioning of the CITAM. As the onlyconsequence, the default value for the CITAMpassword does not consist of the serial numberbut of "CITAM00000". In the CITAM, the serialnumber has no other function.

The CITAM has beenconfigured via DIPswitches and has thenbeen switched on. After ashort while, the "Fail"display flashes and theCITAM does not work.

The DIP switches have been set to an invalidconfiguration. Upon power-up or RESET, arunnig display informs you on the wrong con-figuration. Configure the DIP switches cor-rectly.

Connection establishmentwith the X.21 dialing pro-cedure at 64 kbps doesnot work and the connec-tion is cleared immedi-ately. With a Datex-Lmodem, however, theconnection can be estab-lished.

A dialing procedure at 64 kbps is to fast for theterminal. Use the SLOWDIAL function.

The CITAM is connectedto a PBX; however, eachoutgoing call is rejectedimmediately.

Set the SUB ADD (AddS) option to "OFF".If the option is set "ON", the CITAM copies thesubaddress behind the call number with oneadditional numeric character and is rejectedupon a PBX check.Specify the call number directly without sepa-rating the last character by "*" or "/" as wasrequired in software releases 2.00 to 2.02.

The CITAM is connectedto an SEL PBX or similarchecking the local subaddress of the connectedTA.

Set the PABX-So option to "Yes".If the option is activated, the CITAM transmitsits own subaddress, if not, the called subad-dress in the ISDN setup sabbaddress field.

A 13 Reference model according toCCITT I.412The CCITT recommendation I.412 defines a reference

model for the subscriber access unit (DTE - Data TerminalEquipment) to the ISDN networks.

Fig. A-8: Reference model, according to CCITT I.412

Coming from the local exchange, the subscriber line leads fromreference point U to the network termination NT1.

The main purpose of this line is matching the subscriber linelink protocol to the protocol used by the local subscriber instal-lation.

Reference point T designates the output of network termination1 (NT1) and, at the same time, the input of network termination2 (NT2), which contains the present local subscriber installa-tion.

Reference point S is located between NT2 and the TE1 ISDNterminal equipment.

Many DTEs (TE2) are still frequently used which are not de-signed for the operation in the ISDN. Therefore, a terminaladapter function TA was defined in the place of the DTE TE1,which represents the link between the conventional interfaces(V.24, X.21, V.35, etc., reference point R) and the ISDN tech-nology.

Up to 8 DTEs can be connected to the reference point S, whichcan be addressed in the 1TR6 protocol in Germany with a dif-ferent EAZ. In the Euro-ISDN, such a differentiation can beachieved via the multiple subscriber number (MSN).
