TANDBERG Videoconferencing System

Camera

The built-in camera includes a high quality colour camera with a fast pan/tilt/zoom action. The camera is controlled by the system’s infra-red remote control and operates pan/tilt, focus and zoom.

Codec

The Codec is the heart of the system. The main task for the Codec is the compression of outgoing video, audio and data, the transmission of this information to a remote site and the decompression of the incoming information. Hence the name Codec. Intelligent Call Management (ICM) and the SoftMux are features built into the Codec.

Remote control

The remote control is used to control all functions of the system. There is a separate remote control for operating the monitor.

Table microphone

The high quality table microphone is specially designed to be used on a table during a video conference.

The ideal location for the microphone is on a flat surface at least 2m (6.5 ft) from the front of the system. The microphone cable should always point towards the system.

The system will automatically equalize sound levels. Loud and soft voices are picked up and transmitted to the far end at approximately the same level.

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. After a few seconds you should see the ‘Welcome’ menu on the monitor.

If this does not help, verify that your monitor is switched on. To switch the monitor on you normally push the power button on the front of the monitor (depending on monitor type).

Welcome menu

After the system has performed a self-test routine, product logo and a ‘Welcome’ menu will be displayed on the monitor. 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.

TANDBERG Videoconferencing SystemGetting 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 off 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.

TANDBERG Videoconferencing System

Getting 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 table 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

TANDBERG Videoconferencing SystemGetting 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

To specify an ISDN sub-address or its LAN equivalent extension address (TCS-4), add a star (*) after 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.
