Digital Service

The following instructions are provided to ensure that you comply with FCC Rules, Part 68.

1.

All direct connections to DDS lines must be made through standard plugs and jacks furnished by the telephone company. No connections can be made to party lines or coin lines. Before connecting your unit, you must do the following: a.

Tell your local telephone company that you have an FCC registered device and that you wish to connect to the company’s line. Provide them with the 14-digit FCC registration number listed on the device’s label. They will also need to know the facility interface code and service code to connect the necessary service. For your unit, the facility interface code is 04DU5-56 for 56 kbps service. The service code is 6.0Y.

b.

Inform the local telephone company of the jack arrangement you want to use, which is RJ-48S.

c.

Connect the channel service unit (CSU) with the appropriate cable after the telephone company has installed the requested jack.

2.

If the unit appears to be malfunctioning, it should be disconnected from the telephone line until you learn if your equipment or the telephone line is the source of the trouble. If your equipment needs repair, it should not be reconnected until it is repaired.

3.

The CSU is designed to prevent harm to the DDS network. If the telephone company finds that the equipment exceeds tolerance parameters, the telephone company can temporarily disconnect service, although they will attempt to give you advance notice if possible.

4.

Under FCC Rules, no customer is authorized to repair this equipment. This restriction applies regardless of whether the equipment is in or out of warranty.

5.

If the telephone company alters their equipment or operations in a manner that will affect use of this device, they must give you advance warning so as to give you the opportunity for uninterrupted service.

You will be advised of your right to file a complaint with the FCC.

6.

In the event of equipment malfunction, all repairs should be performed by PictureTel Corporation or an authorized agent. It is the responsibility of the users requiring service to report the need for service to our company or to one of our authorized agents.

Setting Encryption Mode

When your system has the internal encryption option installed, you can configure your system to encrypt both dialed and nondialed

(dedicated) videoconferencing calls using either

automatic

or

manual

encryption.

If your system doesn’t have the internal encryption option, you can also configure 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 General

Configuration menu to configure 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 will either not complete the call or it 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 configure your systems with the same encryption setting.

One exception exists when you configure your site to

Auto Key and place a call: The encrypted call completes if the far-end party has chosen to either disable encryption or enable

Auto Key encryption. The call is encrypted in

Auto Key

mode.

1-7


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.

To set internal encryption (available when your system is configured for

dialed

operation):

Select Set Encryption Mode from the Set General Configuration menu.

Table 1-3 lists the available settings.

If your system is

not

configured with the encryption option, you will not see the

Enable Auto Key

or

Enable Manual Key settings. You won’t see the

Enable External Encryption

or the

Enable External KG-194

settings if you don’t have an RS-449 network interface.

Table 1-3: Encryption Mode Settings

Mode Setting

Disable Encryption

Enable External Encryption

Enable External KG-194

Enable Auto Key

Description

No calls are encrypted (default).

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

Your system uses an external

KG-194 encryption device.

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

1-8


Table 1-3: Encryption Mode Settings (Continued)

Mode Setting

Enable Manual Key

Description

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, you see no video and hear no audio

.

When your system is configured for

nondialed

operation and you choose

Set Encryption Mode from the Set General Configuration menu, you see this message before you see the settings listed above:

Warning: Call in Progress

Continuing will disconnect call

Continue?

No

Yes

1. Choose Yes to continue.

Setting the Wireless Keypad Channel

Your Concorde•4500 system responds to the wireless keypad through the wireless keypad channel. You may need to configure this channel on the system and on its wireless keypad if you are using:

❑

A single videoconferencing system with one or more wireless keypads. Leave the system’s channel setting at the default setting of zero. The system will recognize any keypad no matter what its channel setting is. However, you can only send signals from one keypad to the system at a time.

Any keypad configured for Channel 0 can operate any

Concorde•4500 system. Channel 0 is the universal channel number; any Concorde•4500 system will respond to it.

❑

Multiple videoconferencing systems within close proximity, each using a separate keypad, choose a unique channel number from one to seven for each Concorde•4500 system and its keypad.

Each system and its keypad must have the same channel number to distinguish it from the other systems in the area.

However, you can only send signals from one keypad to a system at a time.

When you have multiple wireless keypads for use with either a single system or multiple systems, use the keypads one at a time. Pressing the buttons on different keypads at the same time can cancel out their signals.

Note:

You do not need to perform this procedure for the

QuickPad.

Enabling 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 — 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

Adjusting the System

Once you have the system fully installed and powered up, you need to test the video and audio levels and adjust them, as necessary. You use the SMPTE (Society for Motion Picture and Television

Engineers) color bars test pattern to test and adjust the monitor tint, color, contrast, and brightness. While the color bars display on the screen, a

1

-kilohertz (kHz) tone sounds. This tone enables you to test and adjust the system volume.

You may also need to adjust the camera white balance to room lighting conditions, as well as adjust the focus. This chapter contains instructions for performing these adjustments.

Adjusting

System Audio

Levels

This section describes how to test the audio on a system using monitor speakers and lists the supplies you need to perform these tests.

For a world cart with Bose speakers, there is no audio system calibration required. Just use the keypad volume controls to adjust the volume to a comfortable level.

What You Will Need

You need a sound pressure meter.

Testing the Audio

To test the audio on the monitor’s speakers:

1. Following the procedure on page 2-1, display the SMPTE color

bars and sound the 1-kHz tone.

2. Select Run Video-Audio Test Pattern from the Near-End Tests menu.

The 1-kHz test tone is set to its nominal level.

T I P

After you have set the monitor volume control, you should adjust loudness with the keypad volume control and not with the monitor volume control.

3. To exit from the test, press HANG UP.

2-6

Adjusting System Audio Levels

Adjusting the Audio

To adjust the volume for your monitor’s speakers:

1. Position the keypad and all additional microphones where you plan to use them in the conference room.

2. Reset the echo canceler by pressing the main system power switch on the electronics module.

3. Display the SMPTE color bars and sound the 1-kHz tone by using the “Testing the Video” procedure at the beginning of this chapter.

4. To adjust the audio level using a sound pressure meter:

a. Place the microphone of a sound pressure meter at a location representing a normal listening position.

Make sure that the sound pressure meter is pointing toward the room loudspeakers.

b. Adjust the monitor volume control (or the amplifier

LEVEL knobs) until the sound pressure meter reads 74 dBSPL.

T I P

In big rooms, take measurements at important listening positions and set the volume to a level as close to 74 dBSPL as possible at all of the positions.

5. Press HANG UP to terminate the test.

2-7


6. Verify the volume setting by running a local channel loopback test from the Near-End Tests menu:

a. Get an acceptable loudness by turning down the keypad volume control

immediately

.

b. Say “one, two” a few times, pausing each time.

You should hear “one, two” repeated over the speaker, but should

not

hear any following artifacts or squeaks.

Because the echo canceler takes a few seconds of speech to adapt to the room acoustics, you may hear an echo at first.

c. Reduce the monitor volume control slightly, as necessary, until you no longer hear any artifacts or squeaks.

d. Adjust the keypad volume control, as necessary, to maintain an acceptable loudness.

7. Place a call as a final verification.

If participants at the far-end site hear an echo, reduce your monitor volume control slightly.

Follow these guidelines: a. After you have adjusted the monitor volume, do not change the monitor volume setting. Use the keypad volume control, if necessary, to change the volume. The echo canceler then works properly.

b. Do not change the audio tone controls on the monitor.

Distortions could result and could affect the performance of the echo canceler.

c. The echo canceler does not handle distortion. Use the keypad volume control and decrease the volume until any distortion is no longer evident.

Table 3-2: SG3 Network Statistics

Description Interpretation

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

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

The sum of the uncorrected packets for all active channels

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

The number of packets with errors that were received from the far end by each channel and were corrected by the errorcorrection software

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

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.

Concorde•4500 Servicing Guide

for information on pin assignments.

Internal Four-Wire Channel Service Unit (CSU)

The PictureTel Concorde•4500 system supports an internal Channel

Service Unit (CSU) daughter board for connecting to a CSDC 56-kb network or to a four-wire DDS line. The internal CSU interface also provides an EIA RS-449 connector to support the concurrent connection of the system to both a switched and a dedicated network.

The wires in the four-wire switched interface are used as follows:

Two wires transmit data, and two wires receive data.

PictureTel does not use the four remaining conductors.

You must follow these guidelines when providing the cable:

❑

Bring the four unused conductors out to the connector.

❑

Use an RJ-48S jack at the termination point of the extended demarc.

To connect your system to a dialed CSDC network or to a nondialed

DDS network interface:

1. Uncoil the network cables.

2. Plug the RJ-48S cable leads into the network wall jacks.

V.35 Network Interface

The ITU-T V.35 interface operates at data rates that range from 56 through 768 kilobits per second (kbps). An associated RS-366A interface supports dialing. Most manufacturers of CSUs provide an

RS-366A dialing port with the V.35 interface, making the V.35 popular for connecting to switched networks.

The Concorde•4500 system configured with an ITU-T V.35 interface supports integrated services digital network (ISDN) terminal adapters and other network terminating equipment, such as modular processor data modules (MPDMs



) and Northern

Telecom DATAPATH



Data Units (DPUs). The system also supports connections to high-speed interface cards in T1 and other multiplexers.

PictureTel provides the RS-366 cables. In addition, PictureTel provides two female DC-37 to M-34 conversion adapter cables. The adapter cables are connected to the male DC-37 connectors on the electronics modules.


❑

Use a cable length that does not exceed 30.5 meters (100 feet) between the system and the network (with any bit rate).

❑

Use a Belden 9732 (or equivalent) cable.

❑

Provide an M-34 male connector.

RS-449 Network Interface

The EIA RS-449 channel port transmits data signals using the EIA

RS-422 balanced line data transmission standard. This interface operates at the following bit rates:

❑

56 kbps through 768 kbps with the ITU-T Recommendation

H.320 (Link-64E) and SG4

❑

56 through 768 kbps with SG3


❑


When the Concorde•4500 system is set to nondialed mode, it asserts TR and RS. If the DCE requires either of these signals, that signal may have to be provided in the cable. A larger cable, such as a Belden 9732, is then required.

❑

Provide a cable that is no longer than 450 meters (1,000 feet) between the system and the network at 384 kbps.

Resolving

Problems

Diagnostic

Procedures

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.

The Concorde•4500 system has three levels of diagnostic procedures:

Type of Test When Test Runs

System power-on self-tests

Board-level tests

Automatically when the system is powered on

When you choose

Run Automatic

Self-Test from the Near-End

Tests menu

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

5-1

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 efficiently without traveling to your site.

Refer to Chapter 3, “Using the Diagnostic Menus,” 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, cameras, and the keypad.

T I P

If the system does not power on, if you see no video, or if you hear no audio, refer to “Troubleshooting Procedures”

on page 5-3.

Pass-Fail Status

When 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 next board test cycle 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.

You can see the slot number for each board listed next to the board name. Because boards may be in different slots for different systems, the slot number comes from the configuration check that the power-on self-tests run initially.

5-2

Troubleshooting Procedures

Fault History and Fault Code Location

If a power-on self-test fails, the diagnostic software updates the fault history and fault code locations. The fault history indicates whether the diagnostics ran successfully the last time. The fault code location lists the diagnostic codes from the last failing test.

After updating the fault history and fault code locations, the tests stop and initiate the loading of the Communications board software.

During the Communications board boot process, you see the fault code that identifies any board that caused a power-on self-test to fail.

Board Replacements

If 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.

(and/or

2

)


Data rate high, port

1

(and/or

2

)

A call has ended unexpectedly.

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.

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

For example, one channel is set to

400 kbps or two channels are set to

200 kbps.


Data rate low, port 1

(and/or

2

)

You are connected to a Px64 bridge, and the bridge has switched to a mode your system does not support.

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.

(No action is required.)

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

1. Retry the call.


2. Try calling another site to isolate the problem.

1. Connect your 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.



1. Connect your Concorde•4500 to channels with data rates greater than or equal to

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.


1. Try redialing the call.


Network lost, port 1

(and/or

2

)

A call has ended unexpectedly because the signaling from the

CSU indicates that the network connection or connections have been lost.


No channel on port 1

(and/or

2

)

Call disconnected:

Far end

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

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

2. Check the local CSU power and cabling and correct, if necessary; then call the far end to check the status of the farend CSU, power, and cabling.

(and/or

2

)

Call in progress

Port 1

(and/or

2

)

Call not completed:

Call setup failure


It means. . .

Do this. . .

A call has ended unexpectedly because an invalid baud rate was detected for a call using Link-64E

(ITU-T Recommendation H.320).

Calls using the Link-64E protocol must use baud rates in multiples of 56 or 64 kbps only.

The Concorde•4500 is engaged in a point-to-point call.

When your level of screen message display is set to

Extended Messages

, this message appears briefly on the monitor.

A dialed call from your

Concorde•4500 was not completed.

In this case, the far-end CSU answered the call but your

Concorde•4500 received no data or received invalid data from the far end.

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 twochannel call.

3. Check the cabling.


This message goes away after

5 seconds.

1. Check that the phone 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.

and the other site is set to

Manual Key

.

Do this. . .

1. Make sure both sites are set for the same encryption settings on the Set Encryption Mode screen; then redial the call.

2. Redial the call without encryption.


Check the CSU and data cabling.

The Concorde•4500 dialed an X.21 call but failed because no clock signal was present from one of the target CSUs.

(The clock signal is not required until after the network call is complete on RS-449 and V.35 interfaces.)

For example, this message appears when the Concorde•4500 tries to dial a two-line call and only one

CSU is available.

Your Concorde•4500 system has tried to dial a call but has detected an error in the dialing sequence.

Your Concorde•4500 system has established a video call with a videoconferencing system that has an incompatible software version.

1. Check the CSU dialer cabling.

2. Make sure the CSU is set to accept dialing signals from the

Concorde•4500.

Ask your distributor for the latest software release.
