TANDBERG MCU Operator Safety Summary For your protection, please read these safety instructions completely before operating the equipment and keep this manual for future reference. The information in this summary is intended for operators. Carefully observe all warnings, precautions and instructions both on the apparatus and in the operating instructions.
Introduction This User Manual is provided to help you make the best use of your TANDBERG MCU. The MCU enables sites on IP and sites on ISDN to participate in meetings with each other, and at the same time it offers superior quality and ease of use in one fully-featured multipoint control unit (MCU).
Yellow Alarm or Remote Alarm Indicator (RAI) means that the MCU is receiving framing info, but in this framing info the other side tells the MCU that it is not reading the MCU’s transmitted framing info. Typically, this may be a broken connector in the transmit (TX) part of the PRI cable.
NOTE CONNECTOR IS NOT USED MCU Capacity – typical scenarios (16 video sites and 16 telephony calls option) Below is an overview of the number of video calls possible to connect on different bandwidths, when 4xE1 (or 4xT1) PRI ISDN lines are connected. In addition to the video calls, telephony calls can also be added.
- There should be a clearance of 9.1cm between the product and any other product mounted in the rack. Unpacking To avoid damage to the unit during transportation, the MCU is delivered in a special shipping box which should contain the following components: •...
• Make sure that the MCU is accessible and that all cables can be easily connected. • For ventilation: Leave a space of at least 10cm (4 inches) behind the MCU’s rear panel and 10cm (4 inches) in front of the front panel.
CSU between your MCU and the PRI line from your network provider. LAN cable To use the MCU on IP, connect a LAN cable from the ‘LAN 1’ connector on the MCU to your network. The ‘LAN 2’ connector is not used and should be left open.
5. Start a WEB browser and enter the IP-address of the MCU. Default password: ‘TANDBERG’. 6. To configure the MCU for ISDN dial in, enter the PRI numbers and dial in number(s). For details, see the ‘PRI Configuration’ section and the ‘MCU Dial In Numbers’ section under ‘Configure the MCU’.
TANDBERG MCU MCU start-up To start the MCU, make sure that the power cable is connected, and press the power switch button to ‘1’. On the front panel of the MCU the power indicator LED, marked ‘Pwr’, will now turn GREEN.

However, if PRI Trunk Grouping is enabled, the number range for PRI 1 will also apply for PRI 2, 3 and 4. Number Range Start The PRI lines connected to the MCU should have at least one number each, to allow dial in from ISDN. If the PRI line has a range of numbers, the start number must be entered here.
• If you have a PRI with only 12 channels. Set Max channel to 12. Max Channels Indicates the maximum number of B-channels the MCU is allowed to use for each of the PRI-interfaces. For E1 (ETSI/Euro ISDN), the maximum number of channels is 30. For T1 (National ISDN and AT&T Custom), the maximum number of channels is 23.
