LCD MONITORS: Panel sticking and after-image lag
Avoid displaying the same images continuously over a long period of time on the TANDBERG 7000 monitors.
Displaying the same images such as still images for a long time may cause after-image lagging. This may occur in the following two cases:
1. After image lagging due to remaining electrical load
When image patterns with very high peak luminance are displayed for more than 1 minute, after-image lagging may occur due to the remaining electric load. The after-images remaining on the screen will disappear when moving images are displayed. The time for the after-images to disappear depends on the luminance of the still images and the time they had been displayed.
2. After-image lagging due to sticking
When images of the same pattern are displayed continuously for several hours or displayed for a short period of time every day , after-images may remain on the screen due to the sticking of the fluorescent materials. In this case, these images may decrease if moving images are displayed after them, but basically they will not disappear.
Solving after-image lagging problems
If you have got after-image lagging on your monitors, you can reduce the problem to an acceptable level by displaying a white image on the monitors for a few hours. This can be accomplished by focusing the camera towards a white paper and setting maximum brightness. See the ‘User Manual’ for details.
NOTE: Warranty may be invalidated if the precautions listed above are not followed.

Getting started
System start-up
Your system should be in standby mode. When in standby mode, pressing any key or picking up the remote control will wake up the system. An incoming call will also wake up the system.
If the system does not respond, make sure the system is switched on by using the On/Off switch located at the rear of the Codec (see figure below). Af ter a few seconds you should see the ‘Welcome’ menu on the monitor .
If this does not help, verify that your monitor is switched on.
Welcome menu
After a user-definable boot-up logo is shown, the following menu appears on the screen. This menu should provide you with the most important system information. The three color-coded commands shown correspond with the Quick keys on the remote control. This means that to make a call, you can press the green quick-key.
23
Getting started
Basics
The system’s most commonly used functions are accessible directly from the remote control by single key presses. In addition, the user interface is represented by on-screen menus. Individual items within the menus and lists can be selected by moving a white highlighter bar to the desired option.
Quick Keys
The three buttons on top of the remote control refer to the blocks at the bottom of the screen. The text inside the blocks will change depending on which menu is selected. The three Quick Keys have different colors.
Preset keys
Activate pre-stored camera positions.
Video source keys
Activate connected video sources.
Camera control and menu navigation keys
Frequently used keys allowing you to control your own camera and the far end camera, control your volume, select and move self-view, switch your microphone of f and navigate in the menu system.
Dialing keys / Preset keys
Used to make a call. The twelve number keys, (0-9), #, * operate in the same way as on a modern push-button telephone. These buttons are also used when entering a name into a text field.

T ANDBERG Videoconferencing SystemGetting started
Making and ending calls
Making a call
To make a call, enter the number or the IP-address of the unit you wish to call using the Dialing keys and press CONNECT.
ISDN call
The system will, by default, try to connect using Quality: Auto (see t able overleaf). If the requested quality (bandwidth) cannot be established, the system will establish a connection on as high quality as possible.
The SoftMux ensures high reliability and includes the unique Downspeeding feature. If channels are dropped during a meeting, Downspeeding automatically maintains the connection without interrupting the call in progress. The SoftMux also enables you to dial to other videoconferencing equipment, phones and mobile phones in the same way and provides you with on-screen, real-time feedback on the progress of a call.
LAN call
To make a call via a LAN, enter an IP-address by using a * as the ‘dot’ in the IP-address, e.g. 123*3*0*12 will be interpreted as 123.3.0.12. If a gatekeeper is present, you may place IP-calls using “telephone-style” numbers (an E.164 alias), according to the numbering plan implemented in the gatekeeper. The dialed number will then be translated into an IP-address by the gatekeeper.
connect
25
Getting started
TIP
Access Code
If the system requires an Access Code, enter the code and press OK to proceed making a call:
Using sub-address / extension address / MCU password
T o specify an ISDN sub-address or its LAN equivalent extension address (TCS-4), add a star (*) af ter the number and then enter the sub-address/extension address.
Example: 12345678*10 ( <number>*<Sub-address/extension address/MCU password>) When calling to external MCU’s requiring a password (TSC-1), this password can be added after the star (*). If no
password is specified, a menu will prompt you to enter the password (after connected to the MCU).
SUB-ADDRESS IS USED TO ADDRESS DIFFERENT SYSTEMS ON THE SAME ISDN LINE. TCS-4 IS USED TO ADDRESS DIFFERENT SYSTEMS ON A LAN, WHEN DIALING IN VIA A GATEWAY.

MultiSite (MCU)
The system has a built-in multipoint conference unit (MCU), MultiSite, which has the capability to establish meetings with up to 4 video sites (5 if at least one site is a telephone call, ISDN/analogue/mobile).
The video calls in a conference must be connected using the same bandwidth.
A conference can consist of any combination of ISDN/IP sites.
It is possible to have telephone meetings with up to 5 participants.
The MultiSite supports both V oice Switched and Continuous Presence mode (see ‘MCU Services’ in ‘Advanced use’ for description of these modes).
Establishing a conference is done by first making a call to one site. When a call is established with the first site, the other sites are connected one by one.
It is possible to either dial out to the sites or the sites can dial in to the MultiSite.
Both ISDN, IP and mixed ISDN/IP conferences can be
encrypted if all systems supports encryption.
For encrypted calls, there is a maximum bandwidth of 768 Kbps for the whole conference. This means that a 3 site conference will have a maximum bandwidth of 384Kbps per connection, while a 4 site conference will have a maximum bandwidth of 256 Kbps per connection.

By default, all inputs are enabled. Just plug in an audio source and it is active. Audio inputs that are On will automatically be mixed. Select Off to prevent audio/noise from unused inputs or if you want to disable a specific input. The activated audio sources are stored on presets.
Mic 1,2 and 3 are intended for electret type microphones. The microphone inputs are balanced with 24V phantom power.
Audio input 4 is intended for connection to an external microphone amplifier or an external fixed mixer.
EXTERNAL MIXER WHEN USING AN EXTERNAL MIXER, IT IS VERY IMPORTANT THAT THIS IS A FIXED MIXER. AUTOMATIC, SMART AND OTHER TYPES OF ADAPTIVE MIXERS
MIGHT CAUSE THE ECHO CANCELLER TO MALFUNCTION.
Audio input 5 is intended for connection to external playback devices or to telephone add-on hybrids.
NOTE
62
T ANDBERG Videoconferencing SystemAdvanced use
As there is no acoustic echo canceller on this input it should not be connected to any microphones. The audio source connected to this input will be heard from the local speaker.
Audio input 6 is intended for connection to a VCR. It can also be connected to other external playback devices. As there is no acoustic echo canceller on this input it should not be connected to any microphones. The audio entering this input will be heard from the local speaker . If ‘Auto’ is selected, the audio from the VCR will only be heard when VCR is selected as videosource.
Mix Mode
‘Auto’ automatically adjusts the weighting of each microphone to obtain the best possible audio and minimizes the background noise. ‘Auto’ will also attenuate the VCR audio level when someone talks into a microphone. ‘Fixed’ will maintain a constant weighting for all microphones.
Level Settings
Adjust the audio input levels according to which external audio equipment is connected. The on-screen audio level indicator will make it easier to set the correct input level settings. The input level should be adjusted so that the average level reaches the preferred level marker.The audio input s are adjustable in steps of 1.5 dB from 0 dB to 22.5 dB.
The default levels for Mic 1,2 and 3 are set for use with an Audio T echnica A T871 microphone in an average videoconferencing room. The gain can be adjusted correctly for a wide range of microphones.
A few examples of microphone levels are:
Audio T echnica A T871 +3dB (default with system) Audio T echnica A T851R +7dB TANDBERG Audio Science +19.5dB
Audioinputs 4, 5 and 6 are set to a default level which is adhered to by most manufacturers of audio-visual equipment and is a level at which most audio-visual equipment (CD-players, VCRs) will work.

Audio Outputs
Audio out 1 is intended for connection to T ANDBERG Natural Audio, televisions or audio amplifiers. Audio out 2 is intended for connection to audio recording equipment or to a telephone add-on hybrid. The signal is
a mix of audio from both the far end and local end (not from Audio in 5). Audio out 3 is intended for connection to a VCR or other recording equipment. The signal is a mix of audio from
far end and local end (not from Audio in 6). Audio Module: Select Natural Audio Module according to the type of Audio Module installed if this is not
automatically detected.
NEVER CONNECT AUDIO OUT 2 OR AUDIO OUT 3 TO A LOUDSPEAKER PLACED IN THE SAME ROOM AS THE MICROPHONES CONNECTED TO THE
SYSTEM. DOING THIS WILL CAUSE “HOWLING” AND POSSIBLE DAMAGE TO THE SPEAKER SYSTEM.
If an output is ‘Off’, no audio will be sent to that output.
Level Settings - Outputs
Adjust the audio output levels according to the parameters of the external audio equipment connected. These levels should only be adjusted when installing new audio equipment. The default settings are correct for the T ANDBERG Natural Audio module and for most consumer electronics devices (televisions, VCRs, etc.).

T ANDBERG Videoconferencing SystemAdvanced use
Echo Control
Each of the 3 microphone inputs and Audio input 4 have a sep arate echo canceller.
One echo canceller per input
provides more sophisticated control than having one common canceller for all microphones. Echo control is normally set to ‘On’ to prevent the far end from hearing their own audio. Once selected, echo
cancellation is active at all times. The echo canceller continously adjusts itself to the audio characteristics of the room and compensates for any changes it detects in the audio environment. If the changes in the audio conditions are very significant
the echo canceller may take a second or two to re-adjust.
Y ou can choose to switch off the echo canceller for the available audio sources.
ECHO CONTROL SHOULD BE SWITCHED ‘OFF’ IF EXTERNAL ECHO CANCELLATION OR PLAYBACK EQUIPMENT IS USED. IT IS YOUR ECHO CANCELLER
THAT
IMPROVES THE AUDIO QUALITY EXPERIENCED BY THE OTHER SITE. WHEN YOU HEAR AN ECHO OF YOUR OWN AUDIO IT IS MOST LIKELY THE FAR
END’S ECHO CANCELLER THAT IS MALFUNCTIONING.
Noise Reduction
In addition to echo cancellation, the system has built-in noise reduction (NR). NR reduces constant background noise (e.g. noise from air-conditioning systems, cooling fans etc.). In addition, a
highpass filter (Humfilter) reduces very low frequency noise. Choose On+NR to activate both Echo Control and Noise Reduction.
NOTE
65
Advanced use
Room Size
This setting allows optimization of the echo canceller to the acoustic size of the room. Hard walls, many windows etc. might require higher settings than expected. Carpets, curtains etc. might require lower settings. Adjust the setting (NOTE: on the far end) if one of the following symptoms occur:
• There is still some echo of your own audio. Increase the setting.
• The system adapts slowly to acoustic changes in the room. Decrease the setting.
After a change, the system will need a few seconds to re-adjust.
Motion
If you experience echo caused by movements in the room, increase the value.
66
T ANDBERG Videoconferencing SystemAdvanced use
Automatic Gain Control (AGC) Settings
Select ‘On’ to allow automatic adjustments (Automatic Gain Control) of audio levels. When ‘On’, the AGC maintains the audio signal level at a fixed value by attenuating strong signals and amplifying weak signals. Very weak signals, i.e. noise alone, will not be amplified.
Example: In most conferences, the participants will speak at different levels, and be at different distances from the microphones. As a result, some of the p articipant s would be harder to hear than others. The AGC correct s this problem by automatically increasing the microphone levels when “quiet” or “distant” people speak, and by decreasing the microphone levels when “louder” people speak.
TO ENSURE CORRECT BEHAVIOUR OF THE AGC, IT IS CRUCIAL THAT THE LEVELS ON THE INPUT CONNECTORS ARE ADJUSTED CORRECTLY USING THE
AUDIO INPUT LEVEL SETTINGS. THE AGC WILL NOT COMPENSATE FOR SEVERE MISADJUSTMENT OF INPUT LEVELS.
When applying a weak signal in the presence of strong background noise, the AGC might amplify the background noise as well as the signal. Therefore, in noisy environments, it is advisable to turn the AGC off.
Tips for improving the echo canceller performance:
• Place all microphones as far as possible from the loudspeaker. Minimum loudspeaker-microphone dist ance
should be 1 meter .
• Place all microphones as close as possible to the persons speaking. By using several microphones, the ratio
distance loudspeaker-to-mic/mic-to-speaker can be increased. Increasing this ratio improves the echo canceller performance. A void distances above two meters from any participant to his/her closest microphone. If necessary , use several microphones. Also avoid placing microphones less than one meter from any person.
• Place all microphones as far as possible from noise sources.
• Reduce the volume setting. Ensure that the loudspeaker does not distort the audio.

On: The internal speaker will warn you of an incoming call even though the monitor may not be switched on.
Key T ones
The Key Tones may be switched on and off.
Restore Audio Defaults
There are many audio settings and the codec could easily be made unusable by configuring these by mistake. It is therefore possible to return all audio settings to their factory default settings by using Restore Audio Defaults.
• The echo canceller tries to estimate the echo path from the speaker system to the microphones. Moving objects
change this path, therefore try to avoid moving objects. Be especially aware of large objects and objects placed close to either the microphone or the speaker system as these objects will cause severe changes to the echo path.
• Avoid putting paper sheets etc. on the microphone.
• Avoid moving the microphone or loudspeaker .
• In the event of poor echo cancelling, allow the canceller to adapt. After each change, the echo canceller
requires a few seconds to adapt. Do not change the settings without allowing the echo canceller to adapt to the new audio environment.
• In the presence of low frequency noise, enable the noise reduction (NR).

External network settings
Before using the system together with external network equipment, you must specify the network parameters on this page.
THE SYSTEM HAS SUPPORT FOR UP TO 768KBPS/2MBPS USING THE EXTERNAL NETWORK (RS449/V .35/X.21) INTERFACE.
Call Control ‘RS366 Dialing’ is the only dialing protocol and would normally be used together with network clocking ‘RS449/
V35 Compatible’ when the external equipment uses RS366 ports.
‘Leased Line’ is a non-dialing protocol and should be used when two codecs are connected in a point to point connection. Use ‘Leased Line’ when the handshaking signals DTR and CD are available. DTR and CD correspond to the X21 network’s C and I signals.
‘Data T riggered’ mode uses TxData (transmit data), RxData (receive data) and clock signals only. Use ‘Data Triggered’ when no handshake signals are available.
‘Manual’ should be used when no handshake signals are available, and the external equipment requires a constantly connected line.
TO MAKE AN IP CALL WHEN ‘LEASED LINE’ IS SELECTED, ENTER A NUMBER BEFORE PRESSING CONNECT TO ACTIVATE THE DIAL MENU.

Address
Address is defined as the IP-address of a streaming client, streaming server or a multicast address. Giving an address in the range 224.0.0.1-239.255.255.255 will broadcast the stream to any host that has joined the specified multicast group. Specifying normal broadcast address 255.255.255.255 will broadcast to any members on the LAN.
Address Port
If several codecs are streaming to the same IP-address, different ports have to be used in order for the client to know which stream to receive. If the first codec streams on port 2240 and the second codec on port 2250, the client has to specify which port to listen to. Video is transmitted on the specified port, audio is transmitted on the port number 4 above the specified video port, in this case 2244 and 2254.
TTL/Router Hops
This is used for streaming data to limit how many routers the data should pass before it is rejected. If TTL is set to 2, data will not traverse more than 2 router hops.

using voice switching (the site that speaks is streamed).
Local Only the local video will be streamed. Remote Only the far end video will be streamed.
Local and far end audio is always streamed.
Allow Remote Start On Streaming can be started from external user interfaces like the Web-browser or Telnet session.
Off Streaming can only be started from the Video Conferencing System using the remote control, or by
using the Dataport. This will prevent activation of streaming using Web browser or Telnet sessions.
Announcements On The codec will announce to the network that it is streaming. This enables a streaming client (e.g. a PC)
to connect to the codec’s streaming session. Used by Cisco IP/TV.
Off No announcement packets will be transmitted.
Video Rate
Defines the Video streaming rate from the system. Range is 16kbps - 320kbps. In addition, audio (G.711) streaming rate is 64kbps, providing a maximum streaming rate of 384kbps.
Password
Set password so that only participants entering correct password will be able to view the streaming session. Entering a password will prevent unauthorized people from accessing the streaming session.
Start/Stop Streaming
By pressing the Quick Key labeled ‘ S tart Streaming ‘, the Streaming session will start. To stop the stream, press the same quick-key , which will be labeled ‘ S top S treaming ‘ while the streaming-session is active. Pressing Disconnect will also stop the streaming session.
How to view streaming
After streaming is started, an easy way to view the streamed audio/video is to start your Web-browser and enter the IP-address of the streaming system. After the Web p age of the codec is shown, click on ‘Streaming’. Alternatively , enter http://<codec ip-address>/stream.sdp.

E.164 alias
This is the E.164 address of the codec. The E.164 address is equivalent to a telephone number , sometimes combined with access codes. V alid characters are 0-9,* and #.
When using a gatekeeper the codec will send a message to the gatekeeper containing both the E.164 address and the system name of the codec. The codec will not register with the gatekeeper if the E.164 alias is not set.
Use Gatekeeper Auto - The codec will automatically try to register on any available gatekeeper . If a gatekeeper responds to the
request sent from the codec within 30 seconds this specific gatekeeper will be used. If no gatekeeper responds, the codec will not use a gatekeeper for making H.323 calls and hence an IP-address must be specified manually .
Manual - The codec will use a specific gatekeeper identified by ‘Gatekeeper IP-address’. Off - The codec will not use a gatekeeper and an IP-address must be used in order to make an H.323 call.
Gatekeeper IP-address This is the gatekeeper IP-address if you specify ‘Use Gatekeeper: Manual’.
H.323 Prefix
When dialing a number prefixed with digits specified by ‘H.323 Prefix’, and with ‘Net: Auto’, an H.323 call will be placed. Example: H.323 Prefix is ‘555’. Dialling ‘55582’ with ‘Net:Auto’ will select LAN.

NA T, Network Address T ranslation, is used in small LAN’s, often home of fices, when a PC and a videoconferencing system is connected to a router with NA T support. NA T support in the videoconferencing system enables proper exchange of audio/video data when connected to an external videoconferencing system (when the IP traffic goes through an NA T router).
When NA T is On, the NAT Server Address will be shown in the startup-menu: ‘My IP Address: 10.0.2.1 (NAT)’
NA T Address
This must be the external/global IP-address to the router with NA T support. Packet s sent to the router will then be routed to the codec.
In the router, the following port s must be routed to the codec’s IP-address: Port 1720 Port 5555-5560 Port 2326-2365 Please contact your T ANDBERG represent ative for further information.

The system provides two standard RS232 serial ports to allow a computer to be connected for data transfer and control purposes.
WHEN CONNECTING TO A PC THE CONNECTING CABLE MUST BE A STRAIGHT THROUGH RS232 CABLE.
Dataport 1
If you wish to connect a PC to Dataport 1, you must ensure that the PC and the system are identically configured. The available settings are:
Dataport 1 supports 4 different modes:
Data mode
Provides a transparent data channel. This channel can be used for many different purposes such as file transfer, application sharing and more. When using this mode, it is necessary to have a T ANDBERG system at the far end.
Control mode
The control interface provided by the Dataport supports a subset of the Hayes command set as well as a comprehensive set of system specific commands.
This mode maintains communication with the Dataport’s command interpreter at all times. All features available from the hand-held remote control can be accessed through the dataport.
Modem
Allows you to control the system externally via a PC as in Control Mode. Once a call is established, Dataport 1 will automatically switch to Data mode. When the call disconnects, Dataport 1 switches back to Control Mode.
T.120
Provides a data channel supporting the T.120 standard for data communication. Using T .120 sof tware on your PC, you can communicate with other T.120 systems using your PC and your system. Dataport 1 is used for monitor control cable on the T ANDBERG 8000. This means that to enable T.120, this cable must be disconnected from the codec, which is not recommended.
