1-4 Overview

Management

ASMi-51 is managed via an ASCII terminal connected to the front panelCONTROL DCE supervisory port. The ASCII terminal can be connected to thesupervisory either directly or via a modem link.

ASMi-51 provides an Embedded Operation Channel (EOC) for end-to-end systemmanagement and supervision. This management channel operates withoutinterfering with data transmission. Real-time alarms indicate the local and remoteunit status. Full management and monitoring of the local and remote modems isdone via the front panel LEDs and a control terminal.

ASMi-51 provides automatic rate detection in external clock mode for tail-endapplications. It also includes a supervisory port for setup, control and monitoring.

Diagnostics

ASMi-51 has comprehensive diagnostics capabilities that include the following testoptions.

ASMi-51 supports activation of the following loopbacks in compliance with theV.54 standard:

• Local analog loopback

• Remote digital loopback

All tests can be activated from the local unit or from the remote unit. The loopbacktests are activated from the terminal or via the DTE interface (pins ”h” and “j” ofthe V.35 or pins 18 and 21 of RS-530).

ASMi-51 includes an additional loopback – local digital loopback or CLB (channelloopback), RAD's proprietary loopback, which tests the digital section of ASMi-51towards the DTE.

ASMi-51 includes internal Bit Error Rate Tester (BERT) for complete testing of thelocal and remote modem and the link quality without any need for external testequipment. ASMi-51 runs an internal pseudo-random 511-bit test pattern inaccordance with the ITU V.52 standard.

Real Time Alarms

Real time alarms provide real time information on system status indicatingmanagement failure, loss of synchronization, etc.

ASMi-51 also features a log file that stores all alarms and events that occurred inthe unit. These alarms can be displayed and cleared.

Statistics Collection

ASMi-51 stores the MSDSL statistics for the line performance monitoring.

Line Protection

ASMi-51 incorporates a high-voltage line protection in compliance with ITU K.21.

The ASMi-51 modem consists of the following major modules:• MSDSL Interface Module – translates the received and transmitted data from

the line to the DTE interfaces.

• Modem Glue and BERT Logic Module – processes the data from/to theMSDSL interface module. It also generates the pattern signals for the Bit ErrorRate (BER) tests.The pattern generator sends a standard 511-bit, pseudo-random pattern to theremote unit when the user activates the modem diagnostic. At the same time,the pattern receiver checks the data received from the remote unit andcompares it with the standard 511-bit pattern. If any errors are detected, theALM LED indicator blinks. The errors or the BER are also displayed in theappropriate menu on the terminal.

• Administration Data Transfer Module – manages the data transfer betweenthe two modems on both sides of the line.

• Terminal and LEDs Module – provides modem status information via LEDindicators on the front panel, and communicates with the terminal to displaythe modem status. The terminal is connected for configuration, control andmonitoring of ASMi-51.

• Modem Controller – This module, based on a MC68302 microprocessor,controls the ASMi-51 operation.



Functional Description 1-7

• Digital Interface – prepares the digital data coming from the DTE into a datastream for the modem glue logic. In addition it translates the data from themodem glue logic into digital data to be sent to the DTE.Table 1-2 the correlation between the ASMi-51 data rate and MSDSL line rate.

Preparing for the Control Session 4-1

Chapter 4Management from aTerminalThe configuration of ASMi-51 is performed via menu-driven embedded softwareusing a standard ASCII terminal or a PC running a terminal emulation applicationconnected to the front panel CONTROL DCE port. This terminal can be used forperforming the following management activities supported by ASMi-51:• Modifying setup configuration

• Monitoring of device status and settings

• Running diagnostic tests and collecting performance statistics

• Downloading software updates

• Restarting ASMi-51.

4.1 Preparing for the Control Session

This section describes how to prepare ASMi-51 and the supervisory terminal forthe control session.

Control Port Interface Characteristics

ASMi-51 includes a V.24/RS-232 asynchronous DCE port, designated CONTROLDCE and terminated in a 9-pin D-type female connector. The control portcontinuously monitors the incoming data stream and immediately responds to anyinput string received through this port.

The terminal can be connected either directly to the ASMi-51 control port, orthrough a modem or any other type of full-duplex data link. The ASMi-51 controlport interface type must be set in accordance with the connection method, asfollows:• DCE – direct connection to terminals. Since terminals usually have DTE

interfaces, the connection to the port is made by means of a straight-throughcable.

• DTE – connection through a modem or data link. In this case, you need across-cable (also called a null modem cable) to connect to the CONTROL DCEconnector.


Chapter 4 Management from a Terminal ASMi-51 Installation and Operation Manual

4-2 Preparing for the Control Session

The ASMi-51 control port can be configured to communicate at the followingrates: 9.6, 19.2, 38.4 or 57.6 kbps.

The word format consists of one stop bit and 7 or 8 data bits; parity can be odd,even or disabled.

For multidrop operation, each ASMi-51 (local or remote) can be assigned a nodenumber in the range of 1 through 255. Assigning node number 0 to the ASMi-51means that it will accept and answer any message: this is not permitted inmultidrop operation. Node number 0 is however recommended for use with bothpoint-to-point and dial-up modes.

Each ASMi-51 can be assigned a logical name of up to eight characters. The logicalname is sent in each transmission of alarm messages. The name helps the operatorto identify the source of messages that are received by the terminal.

Preparing the TerminalAny standard ASCII terminal (a “dumb” terminal or a personal computer runninga terminal emulation application) equipped with a V.24/RS-232 communicationinterface can be used to configure ASMi-51.

4.7 Installing New Software Releases

This section presents procedures for installing new software releases into theASMi-51 units.

The modem stores two software versions, each of them in one of the two 512-bytesections of its Flash memory, which also contains a boot program. The software isstored in compressed format. The active version is decompressed and loaded intothe ASMi-51 RAM upon power-up. The passive software is kept for the backuppurposes. By default, ASMi-51 is delivered with the active software only.

The new software releases are distributed on diskettes as an *.img file, which isdownloaded to the local or remote modem using the XMODEM protocol. Upondownloading, the new software release becomes active, the former active softwareturns into passive, and the former passive is erased.

If a failure occurs during downloading or decompression, the new version is erasedfrom the Flash and the passive version becomes active. In this case, only oneversion is left stored in the Flash memory.

If an active software becomes corrupted, you can replace it with the passive inboth local and remote ASMi-51 units.

5.3 Performing the Diagnostic Tests

The user-controlled test functions of ASMi-51 consist of the loopback tests, BERTand LEDs test. The purpose of these tests is to determine the source of a break inthe data flow.

Before executing a test, note the following:

• Both local and remote ASMi-51 units must be configured and synchronizedproperly to allow remote loopback activation.

• Only one loopback can be activated at a time, either on the local or remoteunit. The BER test can be run on both units.

Running Loopback TestsASMi-51 supports the local analog and remote digital loopbacks as per ITU V.54.Additionally, ASMi-51 features RAD's proprietary local digital loopback – ChannelLoopback.

Note

3. Choose 'Save' by typing the appropriate number, and press <Enter> toactivate the CLB.

The CLB is initiated. The TST indicators light up on both local and remoteunits.

Deactivating the Loopbacks

You can deactivate a running loopback by typing the number corresponding to theloopback in progress to change its value from ON to OFF and choosing 'Save'.Also, you can deactivate the multiple diagnostic tests running simultaneously byselecting 'Clear All' and then 'Save'.

Once a loopback is deactivated, the TST indicators turn off. In case of the LLB, thesynchronization between the modems is restored within a few minutes.

Running the BER TestingASMi-51 includes an internal BER tester, which tests the line quality and calculatesthe bit error rate in the data stream. The ASMi-51 BERT transmits apseudo-random 511-bit pattern according to V.52 standard. A pattern evaluatorreceives the pattern, compares it to the transmitted pattern and detects errors.

You can run BER testing simultaneously on the local and remote ASMi-modems,thus checking the integrity of the link from both sides of the application at thesame time.

You can run the BER testing only if the local and remote ASMi-51 units aresynchronized.

To activate the BER testing:

1. From the Test menu (see Figure 5-7), type 1 to run the BERT on the localASMi-51, or type 2 to run the BERT on the remote ASMi-51, and then press<Enter>.


2. Type 4, and press <Enter>.The BERT value in parenthesis changes to ON.

3. Choose 'Save' by typing the appropriate number, and press <Enter> toactivate the BERT.

The BERT is initiated. The following LED conditions are observed: The TST indicators light up on both local and remote units.

The TD indicator starts blinking on the local unit.

The ALM indicator blinks whenever an error is detected.

Running LLB+BERT and RLB+BERT

You can also combine the LLB or RLB with the BER testing by activating acorresponding loopback and BERT simultaneously. In this case, an internal patterngenerator connects the standard 511-bit pattern to the transmit input of the DTEinterface. The receive output is connected to the pattern evaluator, whichcompares the received and transmitted patterns, and detects errors. TheLLB+BERT checks the local ASMi-51, the local DTE and connection betweenthem. The RLB+BERT check both the local and remote units, and connectionsbetween them.

Appendix BIR-ETH Interface Module

B.1 General Description

IR-ETH is an interface module for RAD modems, used for converting the Ethernet(10BaseT or 10Base2) electrical levels to the modem TTL levels. It also converts theEthernet protocol to HDLC to enable long-distance transmission and avoid theEthernet collision limitation.

IR-ETH includes an internal, self-learning Ethernet bridge, which enables a highperformance link between two Ethernet segments at a low transmission rate. Thelow-speed HDLC transmission is sent over the link using the modem modulationtechnique. It is converted back to an Ethernet signal at the remote modem.

Figure B-1 shows a typical application using an Ethernet interface bridge. Eachmodem is connected to an Ethernet network via the Ethernet interface bridge.

Introduction D-1

Appendix DIR-IP Interface Module

D.1 Introduction

OverviewIR-IP is a high-performance, miniature IP router based on RAD's unique IP routerchip, the ChipRouter.

IR-IP works by taking each Ethernet frame from the LAN and determining whetherthe IP packet is destined for the IP net on the Ethernet LAN. If not, IR-IP forwardsthe packet to the WAN (MSDSL) link. IP packets received from the WAN link areautomatically forwarded to the LAN if the IP net matches.

IR-IP includes hardware filters which handle all filtering operations at wire speedfrom both LAN-to-WAN and WAN-to-LAN, without dropping a single packet.Filtering and forwarding are performed at the maximum rate of 35,000 and30,000 frames per second (wire speed), respectively. The buffer can hold256 frames of maximum size of 1534 bytes and a throughput latency of oneframe.

IR-IP is available with 10BaseT (UTP) interface and is fullyIEEE 802.3/Ethernet v2 compliant. The IR-IP interface can also operate in fullduplex Ethernet applications.

ASMi-51 equipped with IR-IP interface module can be used as a Frame RelayAccess Device (FRAD) with an integral IP router. RFC 1490 is supported for asingle DLCI on the WAN link. Detection of the DLCI and the maintenanceprotocol is performed automatically. This allows the IR-IP to be used as thetermination unit of IP services over Frame Relay at the customer premises,opposite a Frame Relay switch in the backbone.

Alternatively, Point-to-Point Protocol (PPP) can be run on the WAN link withautomatic negotiation on power-up, as well as support for PAP and CHAPauthentication. With this feature, IR-IP can operate opposite any PPP compliantaccess server or backbone router.

IR-IP supports HDLC, which is especially important for broadcast and multicastapplications where bandwidth overhead is critical.

IR-IP supports IP multicast at wire speed, making it suitable for any multicastenvironment including high speed downstream environments, such as satellite andxDSL. Users on the LAN who register with IR-IP for an IP multicast group using theIGMP protocol filter IP multicast packets at wire speed.

Management and advanced configuration are performed via Telnet.

D-4 IR-IP Management Subsystem, General

D.4 IR-IP Management Subsystem, General

IntroductionThe IR-IP interface module management subsystem supports the followingfunctions:• Preliminary configuration

• Configuration of management access parameters

• Advanced configuration of IR-IP parameters

• Collection and display of statistical performance data

• Maintenance functions, which include:

Software downloading

Resetting of various subsystems

Display of error log

Ping utility, for checking IP connectivity.

The management subsystem of the IR-IP interface module is a separate,independent entity, and therefore it cannot be managed through the ASMi-51management subsystem.

The communication with the IR-IP management subsystem is made through thelocal LAN interface connector of the IR-IP module, designated 10BASE-T, usingthe Telnet protocol. Passwords can be used to prevent unauthorized access.

Accessing the IR-IP Management SubsystemThe IR-IP interface module must be configured in accordance with the specificrequirements of the user’s application before it can be used in the user’s network.As a result, it is not possible to supply default parameters to enable IR-IP to startservice without any preliminary configuration.

Therefore, to enable the user to establish Telnet communication and configureIR-IP, IR-IP is delivered with a factory-default set of parameters. The factory-defaultparameters are automatically used:• Before the IP router is configured by the user, e.g., when a new ASMi-51 with

IR-IP interface module is put into operation

• After the user’s configuration parameters have been erased.

When the factory-default parameters are used, the ERR indicator located on theASMi-51 rear panel, near the IR-IP Ethernet interface connector flashes rapidly(about three times per second).

The flashing of the ERR indicator also serves as a warning to the user that the IR-IPWAN (MSDSL) interface does not send, nor does it receive packets, and thereforeIR-IP can be accessed only from the LAN.

After configuring IR-IP, it starts normal operation and routes the traffic inaccordance with the user-selected configuration parameters.

To change the parameters of an already-configured IR-IP, establish communicationfrom a Telnet host using the assigned IP address.

Note



Performing Preliminary Configuration D-5

Default IP Communication Parameters

The default IP communication parameters of the interface module are:• The default IP address of the IR-IP Ethernet port is 192.168.205.1, and the

default IP subnet mask is 255.255.255.252.

• The port will accept IP communication only from the IP address192.168.205.2. Therefore, as long as the factory defaults are in effect, youmust assign this address to the Telnet host used to configure IR-IP.

Using the IP learning mechanism, as explained below you can change the defaultparameters.

In the default configuration, the IR-IP WAN interface is disabled. In order to enablethe WAN interface, you have to modify the Ethernet port address or the IP subnetmask.

D.5 Performing Preliminary Configuration

GeneralThe software necessary for performing all the management and configurationfunctions is stored in the IR-IP interface module, and therefore you only need aregular Telnet host to perform all the activities described in this appendix.

A Telnet host is any computer, e.g., an IBM PC or compatible that fulfills thefollowing minimum requirements:• A standard 10BaseT Ethernet interface

• A TCP/IP protocol stack, and therefore is capable of supporting IPcommunication through the Ethernet interface

• Telnet client software

• A ping utility.

Outline of Preliminary Configuration To perform the preliminary configuration procedure:

1. Connect the Telnet host to the IR-IP interface module.

2. Configure the Telnet host to enable communication with the IR-IP interfacemodule using the default IP parameters.

3. Establish communication with IR-IP and assign the prescribed IP address to itsLAN interface.

4. Establish again communication with IR-IP and continue the preliminaryconfiguration in accordance with the Quick Setup Menu section below.

Note



D-6 Performing Preliminary Configuration

Connecting the Telnet Host

Before starting the management and configuration activities, it is necessary toestablish IP communication between your Telnet host and the IR-IP interfacemodule. For this purpose, it is necessary to provide a communication path.

Because of the method used to assign an IP address to IR-IP Ethernet port, it isrecommended to connect the Telnet host directly to the IP router 10BASE-Tconnector. This is made by connecting an Ethernet cross cable between theEthernet connector of the Telnet host and the IR-IP connector.

However, you may also connect through a common LAN: in this case, connectyour Telnet host and IR-IP to Ethernet hub ports using straight cables.

Preliminary Telnet Host ConfigurationYou can use the IP learning mechanism to configure the IP communicationparameters of the IR-IP LAN interface. In this case, skip to the Assigning the RouterLAN Interface Address section below.

If you prefer to use the factory-default parameters to establish IP communicationbetween your Telnet host and IR-IP, configure the Telnet host as follows:

1. Temporarily configure the host IP address as 192.168.205.2.

2. The initial destination IP address to be used by the host is 192.168.205.1.

The first step in the preliminary configuration process is to assign the desired IPaddress to the LAN interface of the IR-IP interface module.After an IP address is assigned and saved, you must change the destination IPaddress of the Telnet host to the new address, otherwise it is not possible tocontinue the configuration process. At the same time, you can also change thetemporary IP address assigned to the host (192.168.205.2) back to its permanentaddress.

Assigning the Router LAN Interface AddressThe IP address of the IR-IP LAN interface must be configured as part of thepreliminary configuration process. To simplify this process, IR-IP includes a simpleand convenient IP address learning mechanism.

The IP address can be configured and changed at any time, even after thecomplete IR-IP configuration process has been performed, because it does notaffect other configuration parameters. Moreover, the IP subnet mask isautomatically adapted to the new IP address.

IP Learning Mechanism

To simplify the configuration process, IR-IP has a special mechanism forconfiguring the IP address of its LAN interface. Setting section 1, called IP addresslearning, of the IR-IP DIP switch (Figure D-3) to ON enables this mechanism.

The IP learning mechanism enables IR-IP to learn its LAN interface IP address byreceiving frames sent by a ping utility to the prescribed LAN IP address.

To use the IP learning mechanism, you do not need to know the current address ofIR-IP LAN interface, but only the prescribed IP address.

Note

Note



Performing Preliminary Configuration D-7

The IP address is actually retrieved from the ARP frames sent during pinging tolocate the ping destination, not from the ping frames.

To ensure that the process is correctly performed, it is recommended to check thecontents of the ARP table before starting the ping utility, to make sure that it doesnot contain the address to be assigned to the IP router LAN interface.

To view and edit the ARP table contents:

If the Telnet host you are using runs under Microsoft Inc. Windows™ 95, 98 orNT, use the following procedure to view and edit the ARP table contents:

1. Display the table using the arp -a command.

2. If the table includes the intended IP address, remove it from the table usingthe arp -d command.

If for some reason the IP learning process does not succeed, before repeating itmake sure to remove the IP address from the table.

Assigning a LAN IP Address to a New IR-IP

The following procedure enables you to configure the LAN IP address of a newIR-IP router, i.e., a router using the default parameters (see the Accessing the IR-IPManagement Subsystem section above).

If ASMi-51 is already operating, skip Step 2 in the following procedure.

To configure the IP router LAN address:

1. Make sure the preparations described above have been completed, includingthe configuration of the ping utility.

2. Turn ASMi-51on and monitor the IP router indicators: The INT indicator turns on

The ERR indicator lights steadily for approx. 15 seconds, and then startsflashing at a rapid rate (about three times per second).

If the ERR indicator turns off, skip to the What to Do If ... section below.

3. Set section 1 of IR-IP DIP switch to ON.The ERR indicator starts flashing faster (approximately four times a second).

4. Send a ping to the new address to be used by IR-IP. A confirmation should bereceived after the third ping: after the confirmation, the flashing will slowdown to approximately twice a second.

If your host does not begin to receive ping replies after three unsuccessfulattempts, skip to the What to Do If ... section below.

5. Return section 1 of the IR-IP DIP switch to the OFF position.The ERR indicator must turn off.

At this stage, the communication with IR-IP router is lost, because its IP addresshas been changed. Therefore, you must reconfigure the destination IP address ofthe Telnet host. If you wish, you may also change the temporary IP addressassigned to the host (192.168.205.2) back to its permanent address.



D-8 Performing Preliminary Configuration

After changing the destination IP address of the Telnet host, it is recommended toturn ASMi-51 off for a few seconds and then back on, before continuing theconfiguration of the IP router in accordance with the Quick Setup Menu sectionbelow. At this time, in Step 2 the ERR indicator turns off after the 15-secondinterval.

Changing the LAN IP Address of a Configured IR-IP

The LAN IP address of an already-configured IR-IP can be changed while itoperates, this means it is not necessary to turn ASMi-51off before starting theconfiguration procedure. Note however that the IP traffic flow through IR-IP willbe disrupted until the other stations in the IP network learn the new address.

To change the LAN IP address of an already-configured IR-IP, use the proceduredescribed above for a new IR-IP with the following differences:

1. Configure the destination address of the ping utility to the new LAN interfaceIP address. It is not necessary to change the Telnet host source address.

2. When ready, set section 1 of the IR-IP DIP switch to ON.The ERR indicator starts flashing faster (approximately four times a second).

3. Perform Steps 4, 5 of the procedure used for a new IR-IP.

What to Do If ...

The INT indicator does not light immediately after ASMi-51 is turned on

The IR-IP interface module does not receive power from the ASMi-51 powersupply. Service is required.

After the power-up process ends, the INT indicator shows LAN integrity. It may stayturned off without indicating power supply failure.

The ERR indicator does not light immediately after ASMi-51 is turned on

IR-IP is faulty and must be replaced.

After turn-on, the ERR indicator lights for 15 seconds and then turns off. ACTdoes not light, and there is no response from IR-IP

No software loaded into IR-IP. Download software using the procedure describedin the New Software Download Menu section below.

After turn-on, the ERR indicator lights for 15 seconds, and then turns off. ACTlights from time to time, but there is no response from IR-IP

IR-IP has been configured. If you do not know the current IP address of the LANinterface, erase IR-IP router configuration using the procedure given in the ErasingUser’s Configuration section below.

No ping replies from IR-IP

If your host does not begin to receive ping replies after three unsuccessfulattempts, check the physical connection path between the Telnet host Ethernetinterface and the IR-IP 10BASE-T connector.

The IP learning process is not successful

Check that the prescribed IP address does not appear in the ARP table.

Used to enter the IP subnet mask for the WAN interface.



D-12 Management Access Menu

Default Gateway

Operation without Default Gateway

The IP interface module is intended to enable the extension of LANs through theASMi-51 MSDSL link. Therefore, its default routing operation is different from thedefault routing operation of standard IP routers:

• IR-IP forwards packets with destinations not located on the local LAN throughthe WAN interface

• Packets received from the WAN interface and destined to hosts located on thelocal LAN are forwarded to the LAN; other packets are discarded.

The default operation is used when the Default Gateway field is blank.

Operation with Default Gateway

You can instruct IR-IP to send packets with destinations not located on the localLAN to a specific router, which is called the default gateway. The default gatewaymust be connected to the local LAN.

To use this option, enter the IP address of another router attached to the local LANin the Default Gateway field.

It is very important to obtain the correct parameters from the system administratoror ISP. The most common problem when establishing an IP connection is incorrectconfiguration of IP parameters and default gateway. Do not try to guess theseparameters.

Read Protocol from DIP SwitchesSelecting YES for this parameter forces IR-IP router card to use the WAN protocolselected by section 2 of its DIP switch: PPP or Frame Relay.

If you want to be able to select the WAN protocol by means of the Protocol field(parameter 7) of the Quick Setup menu, select NO.

Protocol

Used to select the WAN protocol to be used by the IP router card: PPP, HDLC orFrame Relay.

This parameter is available only if the Read Protocol from DIP Switches parameteris set to NO.

D.8 Management Access Menu

Using the Ping Function

The Ping option is used to confirm IP connectivity by pinging other IP hosts.Connectivity is confirmed by receiving a reply from the remote (pinged) IP host.

To ping a host:

1. From the Diagnostic Tools menu, type 1 and enter the desired host IP address.

2. Press <Enter> to confirm the destination IP address.

3. To start pinging, type 2 on the Diagnostic Tools screen.After pinging starts, you can monitor the ping status. A typical screen isshown in Figure D-26.

After pinging is started, it continues in the background even if you exit theDiagnostics Tools screen. In this case, a Ping Running message appears in the topupper left-hand corner of the screen.

4. To stop pinging, type 3 from the Diagnostic Tools menu.A Ping Stopped message is displayed.To clear the message and return to the Diagnostic Tools screen, press anykey.

D-28 Erasing IR-IP Software

D.13 Erasing User’s Configuration

The user-defined configuration parameters are stored in the IP router card flashmemory. After the user-defined configuration parameters are erased, the IP routercard automatically loads the default parameters.

You may want to erase the current configuration parameters:

1. Before IR-IP is prepared for operation in a new application.

2. When you cannot configure IR-IP because its current LAN-interface IP addressand/or the Telnet password, are not known.

To erase the user’s configuration:

1. Turn ASMi-51 off.

2. Set all the four sections of the IR-IP DIP switch (Figure D-3) to ON.

3. Turn ASMi-51 on and monitor the ERR indicator: it must turn on and lightsteadily.

4. While the ERR indicator is lit (within 15 seconds), set sections 1 and 2 of theDIP switch to OFF.

The IP router configuration is erased.

If you do not set sections 1 and 2 to OFF within 15 seconds of power-up, the IProuter card ignores the setting of all the four sections to ON and starts normaloperation. In this case, it is recommended to turn ASMi-51 off and then back on.To abort the whole operation, turn ASMi-51 off, return all the four-switch section tothe desired positions, and then turn ASMi-51 on again.

5. Turn ASMi-51 off, and the return all the four sections of the DIP switch to thedesired positions.

D.14 Erasing IR-IP Software

You may erase the IR-IP application software, without erasing the user-definedparameters.

After the application software is erased, IR-IP starts its TFTP server application, andwaits for the downloading of software by a TFTP client connected to its LANinterface. The procedure to be used to download the application software in thiscase is also described below.

You may want to erase the application software if the downloading of newsoftware using the Device Control menu (see Figure D-16) fails, and IR-IP does notfunction properly.

Erasing Application Software

To erase the application software:

1. Turn ASMi-51 off.

Note



Erasing IR-IP Software D-29

2. Set all the four sections of IR-IP DIP switch to ON.

3. Turn the ASMi-51 on and monitor the IP router ERR indicator: it must turn onand light steadily.

4. While the ERR indicator is lit (within 15 seconds), set sections 3 and 4 of IR-IPDIP switch to OFF.

The IP router application software is erased.

If you do not set sections 3 and 4 to OFF within 15 seconds of power-up, IR-IPignores the setting of all the four sections to ON and starts normal operation. In thiscase, it is recommended to turn ASMi-51 off and then back on.Alternately, to abort the whole operation, turn ASMi-51 off, return all the fourswitches to the desired positions, and then turn ASMi-51 on again.

5. Turn ASMi-51 off, and the return all the four sections of the DIP switch to thedesired positions.

Downloading New SoftwareAfter erasing the application software, you can download new software from anycomputer that can serve as a TFTP client.

To enable the downloading, IR-IP automatically activates its TFTP serverapplication with the following factory-default IP parameters:• IP address: 192.168.205.1

• Subnet mask: 255.255.255.252.

Connect the computer serving as a TFTP client to the IR-IP 10BASE-T connector inthe way as a Telnet host used for preliminary configuration (see the PerformingPreliminary Configuration section). The computer IP parameters must beconfigured as follows:• IP address 192.168.205.2

• Subnet mask 255.255.255.252

• Default gateway 192.168.205.1

To download new software:

1. If necessary, turn ASMi-51 off.

2. Set all the four sections of the IR-IP DIP switch to OFF.

3. Turn ASMi-51 on and monitor the ERR indicator: it must start flashing.

4. Connect the computer to the IP router LAN interface and configure its IPparameters as explained above.

5. Run a standard TFTP client application on the Telnet host, and download theappropriate software file.

If the download is successful, IR-IP starts using the new software.If the downloading fails, repeat the download process.

IR-E1 Connector Options E-1

Appendix EIR-E1 2048 kbps UnframedInterface ModuleIR-E1 is an interface module for the ASMi-51 modems that converts G.703 E1unframed signals to TTL levels. The converted data is sent over the modem linkusing the modem's modulation technique. It is then converted back at the otherend into G.703 E1, or any other possible digital interface signal, at 2048 kbpssignals.

E.1 IR-E1 Connector Options

The IR-E1 interface module fits into a standalone modem, and is available withtwo types of physical connections: RJ-45 for balanced twisted pair connection andBNC for unbalanced coaxial connection.
