Notice to Canadian UsersThis digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications (DOC).

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la class A prescrites dans le Réglement sur le brouillage radioélectrique édicté par le ministère des Communications du Canada.

The Canadian Department of Communications label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operational, and safety requirements. The Department does not guarantee the equipment will operate to the user’s satisfaction. Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations. Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment. Users should ensure, for their own protection, that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

DOC Load Number (LN) = 6

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

FCC Part 68 Notice (U.S.)The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device, to prevent overloading. The termination on a loop may consist of any combination of devices subject only to the requirement that the total of the Load Numbers of all the devices does not exceed 100.Ringer Equivalence Number (REN) = .6B

Monitors

Monitors The Concorde¥4500 main monitor looks like a television set. It displays far-end and near-end videoconferencing sites, system menus, online help, video from a VCR, or high-resolution, still- image snapshots. The picture-in-picture (PIP) window is an area in the lower right corner of the screen that is usually used to display the image you are sending to the far-end site.

If your system has an optional graphics monitor, then you have an additional monitor connected to your system. With a graphics monitor, you can view high-resolution snapshots or live, preview video on one screen while you simultaneously view the far-end site on the other screen.

Figure 1-4: Main Monitor

F Y I F.Y.I. Only the main monitor of a dual-monitor system has a PIP window.

Electronics Module

The electronics module is a self-contained unit that includes the system electronics, the system software cartridge, and the power supply. The back of the electronics module exposes the connection panel where the cables connect to the system. The electronics module sits in the bottom of the WorldCartª.

Figure 1-5: Electronics Module

Cameras

Cameras The PowerCamª 100, used as the main camera for the Concorde¥4500, is a compact, modular, pan-tilt-zoom (PTZ) camera. It has an infrared signal receiver that enables you to control your videoconference from the keypad. The camera is Þxed to the top of the monitor.

You may also have an auxiliary camera, which is typically a pan-tilt-zoom camera mounted on a tripod. This camera is particularly useful when you want to focus on a conference room tool, such as a ßip chart or an exhibit.

Figure 1-6: PowerCam 100

LimeLight LimeLightª is an automatic, camera-pointing device that senses voices in a room and points the camera towards the speaker. LimeLight automatically calculates the correct pan angle, tilt angle, and zoom range of the camera. If two or more people in the room get into a conversation, LimeLight adjusts to include all speakers in the frame.

For ideas on how to use automatic camera pointing most effectively, see ÒTips for Using LimeLightÓ under the Tips tab in the Concorde¥4500 UserÕs Notebook.

Microphones

Microphones The Concorde¥4500 uses the PowerMic , a domed circular microphone that is placed on your conference room table. It connects to the back of the electronics module. You can use more than one PowerMic if you have a large conference room. In fact, you can serially connect up to four PowerMics for use with your system. The PowerMic is packaged with its own documentation, which describes how to install and use it.

The PowerMic equalizes sound. Loud voices, soft voices, and even whispers are picked up and transmitted to the far end at approximately the same volume.

If you choose to walk around the room during a videoconference, you may want to use the optional lapel microphone.

Figure 1-8: PowerMic

WorldCart The WorldCart is a fully-integrated, roll-about cart for the Concorde¥4500. The system monitor attaches to the top of the cart. A pull-out drawer, located behind the front doors, provides storage for the PowerMic, wireless keypad, Look-At-Me-Buttonª (LAMBª), and the Concorde¥4500 documentation.

The electronics module sits in the lower portion of the cart. Shelves are available to hold additional items, such as a modem or a VCR. A Bose¨ speaker is built into the front of the cart.

If your system also has a graphics monitor, the second monitor may be attached to another WorldCart. The second cart is similar to the main cart except that it does not contain an electronics module or Bose speakers.

Look-At-Me-Button

Look-At-Me-Button

The Look-At-Me-Button is a wireless device that allows you to preset camera views with the Concorde¥4500. You can mount the LAMB on a wall near a whiteboard or other point of interest, or place it on your conference room table. The large blue button in the center of the LAMB works just like the camera preset buttons on your keypad.

The LAMB has two other buttons, MUTE and SHOW ROOM. Pressing MUTE blocks sound from your microphones, so that no sound is sent to the far end. Pressing SHOW ROOM moves your main camera back to a wide-angle room view.

Enabling and Configuring H.331 Broadcast Mode

H.331 broadcast mode is a feature that enables you to have a videoconference in which one site transmits video and audio to many sites. The receiving sites can see and hear video and audio from the sending site (the broadcaster), but the broadcaster does not receive any video or audio from the other sites. This is known as a broadcast transmission Ñ in other words, a one-way transmission.

When the H.331 broadcast mode feature is enabled, your system can communicate with a terminal or a multipoint bridge that supports this feature. The sending site and the receiving sites must have the H.331 broadcast mode enabled on their systems to participate in the H.331 broadcast videoconference.

Here are some tips to help you use Auto IMUX Dialing most effectively:

❑ If you want to conÞgure your system for Auto IMUX Dialing and the video numbers in Dialing Directory entries contain embedded IMUX codes, you should remove these codes for Auto IMUX Dialing to work most effectively. The Convert Dialing Directory Numbers screen provides a conversion routine to simplify this process. To remove embedded IMUX codes, see ÒConverting Dialing Directory NumbersÓ on page 2-20.

❑ If people in your organization call one site with multiple transmission rates, store the most common rate in the Dialing Directory. When users want to use less common rates, they can override this setting by choosing Change Rate for This Call from the Dialing Directory.

❑ If you want users to use the rates you choose when they make calls, disable the Change Rate for This Call feature by choosing Let User Change Call Rate [No] from the Set Network Interface menu.

❑ To simplify rate selection menus for users, leave the IMUX codes blank for rates that no one uses.

Setting Encryption Mode

When your system has the internal encryption option installed, you can conÞgure it to encrypt both dialed and nondialed (dedicated) videoconferencing calls using either automatic or manual encryption.

If your system doesnÕt have the internal encryption option, you can also conÞgure your system to use an external cryptographic device, such as KG-84, for either a dialed or a nondialed network. External devices offer an even higher level of security and can be used only with the RS-449 network interface.

The instructions in this section tell you how to use the Set General ConÞguration menu to conÞgure your system to use internal or external encryption.

The following basic guidelines apply to using encryption:

❑ The internal encryption option functions only with PictureTel System 4000 videoconferencing systems using SG3 video transmission mode.

❑ If you are attempting to make an internally encrypted call, make sure that your system has H.331 broadcast mode disabled. If your system is set for internal encryption and for H.331 broadcast mode, the system either will not complete the call or will ignore the H.331 broadcast mode and result in a point-to-point call.

❑ You can use the PictureTel internal encryption option when you must conform to the Data Encryption Standard (DES) of the United States National Bureau of Standards. Both your system and the system you call must have the encryption option installed.

❑ If you are using an external encryption device, both your system and the system you call must use identical devices.

❑ Both you and the far end must conÞgure your systems with the same encryption setting.

F Y I F.Y.I. You cannot legally export a system with the internal encryption option installed from the United States without the expressed approval of the United States Department of State. Your PictureTel sales representative can assist you.

4-5


To set internal encryption (available when your system is conÞgured for dialed operation):

1. From the Set General Configuration menu, select Set Encryption Mode.

Table 4-3 lists the available settings.

F Y I F.Y.I. If your system is not conÞgured with the encryption option, you will not see the Enable Auto Key or Enable Manual Key settings. You wonÕt see the Enable External Encryption or the Enable External KG-194 settings if you donÕt have an RS-449 network interface.

Table 4-3: Encryption Mode Settings

Mode Setting Description

Disable Encryption No calls are encrypted (default).

Enable External Encryption Your system uses an external encryption device (RS-449 interface only).

Enable External KG-194 Your system uses an external KG-194 encryption device.

Enable Auto Key Your system initiates a video call by generating the encryption key; the far end automatically receives the decryption key and decrypts the call.

Enable Manual Key Both you and the far-end party must enter the same decryption key on the keypad for each call. For example, if you choose 7344590, the party you are calling must also choose 7344590.If you enter different keys, the call connects but you see no video and hear no audio.

7-4


The following table describes the current network channel statistics for SG3 communications.

Table 7-2: SG3 Network Statistics

Statistic Description Interpretation

Checksum Errors The sum of video errors that were not caused by an error in the channels

A large number of errors indicates a faulty transmitting AP board at the far-end site or a faulty receiving AP board at the near-end site.

After the call, place the systems at each site in local channel loopback mode. The system with the checksum errors has the faulty board.

Packet Dropouts The number of packets with errors that were discarded because they included an uncorrectable error or could not be decoded

High numbers indicate a transmission line problem or, less frequently, a CSU problem. If your system uses an external CSU, the cabling to the CSU may be faulty.Verify the numbers by running a near-end local channel loopback test.

Packet Errors The sum of the uncorrected packets for all active channels

Refer to the interpretation for Uncorrected Packets.

Error Free Packets The number of packets received from the far end by each channel without error

This indicates that the transmission line and the CSUs are valid.

Corrected Packets The number of packets with errors that were received from the far end by each channel and were corrected by the error-correction software

Small numbers for this statistic are expected during normal operation.

Table 7-3: SG4 and H.320 Network Statistics


Channel Use Initial for channel 12nd ch for channel 2

This line indicates the logical channel number that is being transmitted or received on the individual ports.

Tx Clock Transmit clock This number indicates the transmit data rate.

Rx Clock Receive clock This number indicates the receive data rate.

Chans - Tx/Rx The transfer rate This number should correspond to the Tx or Rx Clock rates:

1B = 64000 1Br = 56000

1H0 = 3840001H0r = 336000

Tx Frames The number of H.221 frames transmitted

This count continually increments during an SG4 or H.261 call or while an SG4 or H.261 call is being attempted.

Rx Frames The number of H.221 frames received

This count continually increments during an SG4 or H.261 call or while an SG4 or H.261 call is being attempted.

Rcv Err Bit The number of H.221 error bits received from the far-end system

The far-end system has indicated a problem in the data it is receiving. This statistic represents an end-to-end quality monitoring feature.

Alignment Lost The number of times the SG4 or H.261 frame alignment signal has not been received as expected

Usually this count, which indicates the integrity of the end-to-end connection, increments by one at the end of a call or when a far-end loopback test is initiated.

Any other change in this counter indicates a failure of the transmission line or, less frequently, a CSU problem.

7-7


Vid Fs Total The total number of video frames received

This number indicates that video is being received.

Fixed The number of video frames received with a correctable error

A high number may indicate a transmission line problem.

Verify by checking the Alignment Lost count.

Also, refer to the BAS Er statistic.

UnFixed The number of video frames received with an error that could not be corrected

A high number may indicate a transmission line problem.

Verify by checking the Alignment Lost count and by checking that the Tx and Rx clocks agree with the Chans - Tx/Rx numbers.

Also, refer to the BAS Er statistic.

BAS Er The number of unrecognized command or capability codes (BAS codes) received from the far-end system

This number may indicate that the far-end system is sending commands or capabilities that the near-end system does not recognize.

It may also mean that there is a transmission line problem, especially when coupled with high numbers of Þxed and unÞxed video frames or alignment losses.

High numbers may be normal when you are communicating with products from other manufacturers.

Checksum Errors The sum of video errors that were not caused by an error in the channels

A large number of errors indicates a faulty transmitting AP board at the far-end site or a faulty receiving AP board at the near-end site.

After the call, place the systems at each site in local channel loopback mode. The system with the checksum errors has the faulty board.

ResolvingProblems
Using the procedures in this chapter, you can monitor system functionality, discover where a problem exists, and initiate recovery procedures to maintain your system at peak performance.

Diagnostic Procedures

The Concorde¥4500 has three levels of diagnostic procedures. The following table describes them:

Table 8-1: Diagnostic Procedures

Type of Test When Test Runs

System power-on self-tests Automatically when the system is powered on

Board-level tests When you choose Run Automatic Self-Test from the Near-End Tests menu

Run-time and loopback tests When you choose speciÞc tests from the Near-End Tests menu or the Far-End Tests menu

8-1

RESOLVING PROBLEMS

In addition, you can have an authorized PictureTel service provider run remote diagnostic tests on your system. After you coordinate with your service provider and select to run these tests, the diagnostic tests program reboots your system and sends data through the modem to a PC. The service provider can then analyze your system quickly and efÞciently without traveling to your site.

Refer to Chapter 3, ÒUsing the Diagnostic Menus,Ó for instructions for running any of the diagnostic tests.

Verifying Power-On

The power-on self-tests check the hardware and verify the presence of system boards and cameras.

Pass-Fail StatusWhen a test cycle for a board completes, a PASS or FAIL status message appears next to the board on the screen listing. If a board fails a test, the remaining tests in the cycle for that board are then aborted, and the diagnostics continue with the test cycle for the next board in an attempt to power on the system. After all of the boards have been tested, if any of the boards have failed, a message appears asking you to press any key to continue system startup.

In addition, if a test fails, the red LED on the failed board is lighted instead of the green LED.

T I P

If the system does not power on, if you see no video, or if you hear no audio, refer to ÒTroubleshooting ProceduresÓ on page 8-3.

F Y I F.Y.I. The slot number for each board is listed next to the name of the board.

8-2

Troubleshooting Procedures

Fault History and Fault Code LocationIf a power-on self-test fails, the diagnostic software updates the fault history. The fault history indicates whether the diagnostics ran successfully the last time.

After updating the fault history, the tests stop and initiate the loading of the Communications board software. During the Communications board boot process, the fault code appears that identiÞes any board that caused a power-on self-test to fail.

Board ReplacementsIf a power-on self-test fails after you have rebooted the system and continues to indicate that a board is not functioning properly, you should replace the failing board. Contact your authorized PictureTel service provider.

If, after the new board is installed, the test continues to fail, call your PictureTel service provider.

RESOLVING PROBLEMS

Verifying Electrical Current

Have a licensed electrician test the current from the electrical wall connection and make sure that the current meets engineering speciÞcations if the following conditions exist:

❑ The LEDs on the electronics module do not light.

❑ The PictureTel Ready message is not displayed.

Warning

A licensed electrician must perform this veriÞcation.The voltages present can cause fatal injury.

Have a licensed electrician verify the electrical current, as follows:

1. Make sure that the main AC power cable is not connected to the system, and plug the cable into the wall outlet.

2. Verify that the AC voltage from the wall outlet meets specifications. Do this by plugging the leads from a digital voltmeter into the system end of the cable in each of the following two positions:

a. Plug the voltmeter leads into the hot and neutral leads of the AC cable.

b. Plug the voltmeter leads into the hot and ground leads of the AC cable.

3. Verify the AC power cable by plugging one voltmeter lead into the neutral lead and the other voltmeter lead into the ground lead.The reading should be under 1 VAC.

4. Verify that the AC voltage from an additional AC source, used for optional equipment, is at the same voltage as the main AC power source. Do this by plugging the leads from the digital voltmeter into the system ends of the two cables in each of the following positions:

a. Plug the voltmeter leads into the ground leads of the AC cables.

The reading should be zero.

b. Plug the voltmeter leads into the neutral lead of one AC cable and into the ground lead of the other AC cable.The reading should be under 1 VAC.

System Messages
This appendix describes the system messages that may appear on the monitor while you are using the Concorde¥4500.

There are two types of system messages:

❑ General messages

❑ Call progress messages

The table on the next page lists the system messages in alphabetical order. The table includes the message, its signiÞcance, and, when appropriate, a suggested response. The shaded entries appear only if you conÞgure your system to display extended messages.

General Messages

General messages tell you the state of your system.

Some general messages indicate a problem with the system. If so, follow the steps listed in the table to try to resolve the problem.

Some general messages are purely informative. In these cases, you donÕt need to do anything. Often, these messages only appear brießy. For example, Call in progress appears when a call connects successfully.

F Y I F.Y.I. You can conÞgure your system to display normal messages, extended messages, or no messages. To set the message type, choose Set Screen Message Display from the Set General ConÞguration menu, available from the ConÞguration menu.

C-1

SYSTEM MESSAGES

Call Progress Messages

Call progress messages tell you the advancing stages of your call as it connects, and, if there is a problem, why the call wonÕt go through.

F Y I F.Y.I. If your system is conÞgured with an X.21 network interface and you are using an IMUX or a terminal adapter (TA) that supports X.21 messages, you will see the X.21 call progress messages in addition to the system messages listed in the following table. For more details, see Appendix D, ÒX.21 Call Progress Messages.Ó

Table C-1: Concorde•4500 System Messages

If you see. . . It means. . . Do this. . .

Audio-only in effect You are connected to a Px64 bridge, and the bridge has switched to a mode your system does not support.

(No action is required.)

You can continue participating in the conference in audio-only mode.

Call aborted A call has ended unexpectedly. Retry the call.

Call disconnected:Data lost, port 1(and/or 2)

A call has ended unexpectedly because data was lost on the channel indicated. Data loss can be due to transmission line errors, data cable problems, a turned off or disconnected far-end CSU or system, or unsynchronized external encryptors.

1. Retry the call.

2. Try calling another site to isolate the problem.

C-2


Call disconnected:Data rate high, port 1(and/or 2)

A call has ended unexpectedly because the combined channel data rate exceeded the maximum allowable rate.

1. Connect the Concorde•4500 to channels so that the data rate is not greater than 768 kbps for one channel or 128 kbps (total) for two channels.

2. Retry the call.


Call disconnected:Data rate low,port 1(and/or 2)

A call has ended unexpectedly because the combined channel data rate has fallen below the minimum allowable rate.

For example, a channel is set to less than 1.2 kbps.

1. Connect the Concorde•4500 to channels with data rates greater than or equal to 1.2 kbps.

2. Retry the call.


Call disconnected:Invalid data

A call has ended unexpectedly because invalid data was received. Invalid data can consist of unexpected forms of data arriving at the Concorde¥4500 or a mismatched encryption master key. (A master key mismatch can occur only when both systems are set to Manual Encryption.)

If the manual key or the auto session key encryption is being used, then do the following:

1. Reenter the master encryption key, and retry the call.

2. Make sure that both sites use the same master key.

3. Retry the call using the Auto key or no encryption.

A call has ended unexpectedly because the clock signals expected from the CSU are missing.

1. Check the CSU power, switch settings, and cabling.


Call disconnected:Far end

The far-end operator has disconnected the call using the normal disconnect (or hang-up) procedure.


Call disconnected:Non H.320 rateport 1 (and/or 2)

A call has ended unexpectedly because an invalid baud rate was detected for a call using ITU-T Recommendation H.320. Calls using the H.321 protocol must use baud rates in multiples of 56 or 64 kbps only.

1. Check the baud rate settings for your lines.

2. Make sure that baud rates for both lines are identical if you were attempting to make a two-channel call.

3. Check the cabling.

Call in progress The Concorde¥4500 has successfully connected to the system called. The system is now engaged in a call.


This message only appears brießy.



C-4


Call not completed:Call setup failure

A dialed call from the Concorde¥4500 was not completed.

In this case, the far-end CSU answered the call but the Concorde¥4500 received no data or received invalid data from the far end.

1. Check that the numbers dialed are correct.


3. Check the cabling between the Concorde•4500 and the network.

4. Ask the far-end operator to check the far-end cabling between the system and the network.

X.21 Call Progress
Messages

This appendix describes the X.21 call progress messages that may appear on the monitor while you are using the Concorde¥4500.

Call progress messages tell you the advancing stage of your call as it connects, and, if there is a problem, why the call wonÕt go through.

The Concorde¥4500 generates some call progress messages internally. These appear on the screen regardless of your systemÕs network interface. The internal call progress messages are listed with the system messages in the table in Appendix C, ÒSystem Messages.Ó

The X.21 call progress messages are listed in the table on the next page. The messages are listed in order by X.21 code. The table contains three columns. The Þrst column lists the call progress message. The second column lists the X.21 text and code and, when appropriate, an explanation. When applicable, the third column lists the corresponding Q.931 cause and code.

There are two types of X.21 call progress messages:

❑ Normal messages

❑ Extended messages

F Y I F.Y.I. The X.21 call progress messages appear only if your system is conÞgured with an X.21 network interface and you are using an IMUX or a terminal adapter (TA) that supports X.21 messages.

D-1

X.21 CALL PROGRESS MESSAGES

Normal MessagesNormal messages display basic information.

When you display normal messages, and a call successfully connects, the text from the Þrst column of the following table appears. When a call fails to connect, the message includes a suggested user response, for example, Check number — dial again.

Extended MessagesExtended messages provide more technical detail than normal messages.

When you display extended messages, and a call successfully connects, the heading and code from the second column of the following table appear. When a call fails to connect, the message appears along with the suggested response from the Þrst column.

F Y I F.Y.I. You can conÞgure your system to display normal messages, extended messages, or no messages. To set the message type, choose Set Screen Message Display from the Set General ConÞguration menu, available from the ConÞguration menu.

This cause indicates that the equipment sending this cause has received a request to establish a call which has low layer compatibility, high layer compatibility, or other compatibility attributes (for example, data rate) which cannot be accommodated.

Recovery on timer expiry (102)

This cause indicates that a procedure has been initiated by the expiry of a timer in association with error handling procedures.

Temporary network failure.


Out of order (44)

The remote number is out of order. Possible reasons include:

❑ DTE is uncontrolled not ready

❑ DCE power off

❑ Network fault in the local loop; in packet switched services only:

¥ X.25 layer 1 not functioning

¥ X.25 layer 2 not in operation

Temporary failure (41)

This cause indicates that the network is not functioning correctly and that the condition is not likely to last a long period of time; the user may wish to try another call attempt almost immediately.

Network out of order (38)

This cause indicates that the network is not functioning correctly and that the condition is likely to last a relatively long period of time; immediately re-attempting the call is not likely to be successful.



D-11


Call rejected by network.


Controlled not ready (45)

Called DTE is signaling controlled not ready.

Call rejected (21)

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

This cause may also be generated by the network, indicating that the call was cleared due to a supplementary service constraint. The diagnostic Þeld may contain additional information about the supplementary service and reason for rejection.

Destination is out of order.

Notify end-user at destination.

Uncontrolled not ready (46)

Called DTE is uncontrolled not ready.

Destination out of order (27)

This cause indicates that the destination indicated by the user cannot be reached because the interface to the destination is not functioning correctly. The term Ònot functioning correctlyÓ indicates that a signaling message was unable to be delivered to the remote party; for example, a physical layer or data link layer failure at the remote party, or user equipment off-line.

Destination is not powered.


DCE power off (47)

Called DCE has no main power or is switched off.

n/a



D-12

Bearer capability not implemented.


Invalid facility request (48)

A facility requested by the calling DTE (circuit switching or packet switching services) or the called DTE (packet switching service only) is detected as invalid by the DCE at the local DTE/DCE interface. Possible reasons include a request for a facility which has not been subscribed to by the DTE; a request for a facility which is not available in the local network; or a request for a facility which has not been recognized as valid by the local DCE.

Bearer capability not implemented (65)

This cause indicates that the equipment sending this cause does not support the bearer capability requested.

Channel type not implemented (66)

This cause indicates that the equipment sending this cause does not support the channel type requested.

Service or option not implemented, unspeciÞed (79)

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

Local loop fault at destination.


Network fault in local loop (49)

The local loop associated with the called DCE is faulty.

n/a

Number temporarily unreachable.


Call the information service (51)

The called number is temporarily unobtainable. Call the network information service for details.

n/a



D-13


Bearer capability not authorized.


Incompatible user class of service (52)

The called DTE belongs to a user class of service which is incompatible with that of the calling DTE.

Bearer capability not authorized (57)

This cause indicates that the user has requested a bearer capability which is implemented by the equipment which generated this cause but which the user is not authorized to use.

All circuits are busy.

Try again later.

Network congestion (61)

A condition exists in the network such as temporary network congestion, temporary fault condition within the network (including procedure error within a network), or an international link.

Switching equipment congestion (42)

This cause indicates that the switching equipment generating this cause is experiencing a period of high trafÞc.

Resource unavailable, unspeciÞed (47)

This cause is used to report a resource unavailable event only when no other cause in the resource unavailable class applies.

Bearer capability not presently available (58)

This cause indicates that the user has requested a bearer capability which is implemented by the equipment which generated this cause but which is not available at this time.

All circuits are busy.

Try again later.

Long-term network congestion (71)

A major shortage of network resource exists.

n/a



D-14

Network interworking problem.


RPOA out of order (72)

The Remote Point of Access (RPOA) nominated by the calling DTE is unable to forward the call.

Interworking, unspeciÞed (127)

This cause indicates that there has been interworking with a network which does not provide causes for actions it takes. Thus, the precise cause for a message which is being sent cannot be ascertained.

[none] Registration/cancellation confirmed (81)

The facility registration or cancellation requested by the calling DTE has been conÞrmed by the network.

n/a

[none] Redirection activated (82)

The redirection facility is active.

n/a

[none] Redirection deactivated (83)

The redirection facility is not active.

n/a



D-15


[none] n/a Normal call clearing (16)

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

Normal, unspeciÞed (31)

This cause is used to report a normal event only when no other cause in the normal class applies.

Quality of Service not available (49)

This cause is used to report that the requested Quality of Service, as deÞned in Recommendation X.213, cannot be provided (for example, throughput or transit delay cannot be supported).
