TANDBERG MCUIntroduction
Front view
The front of the MCU contains 24 Light Emitting Diodes (LEDs) organized in three groups. These diodes provide
information about PRI-line status, LAN (Ethernet) connection and power.
The TANDBERG MCU
Red Alarm or Loss of signal (LOS) indicates that there is no signal and thus no framing info received. The same
effect will be obtained by pulling out the PRI cable. This may also be caused by a broken connector in the receive
(RX) part of the cable.
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. This could also indicate weak or noisy signal in the
transmit (TX) part of the PRI cable.

Name Name of the conference. The conference name will be shown on the ‘Conference
Overview’ page and on the ‘Conference Status’ page.
Default Call Type Specifies the default call rate that the MCU shall use when dialing to a
participant. It is also the maximum rate allowed in the conference. If a participant
does not support this rate, the MCU will connect at the highest rate possible.
The call rate can be set to: Telephone, 64 kbps, 2x64(h221) kbps, 128 kbps, 192
kbps, 256 kbps, 320 kbps, 384 kbps, H0 (384 kbps), 512 kbps, 768 kbps, 1152
kbps, 1472 kbps and 1920 kbps.
If ‘Telephone’ is selected, an audio bridge will be created and no video
participants will be able to join.
Restrict (56K) When unselected, the MCU will set up an non-restricted call and downspeed to
56kbps if necessary. Select ‘Restrict (56)’ if the MCU should set up restricted
calls by default.
Non-restricted and restricted calls are supported in the same conference.
Allow Incoming Calls When selected, incoming calls are automatically answered. If unselected, all
incoming calls will be rejected.
Cascading Mode Used when two or more conferences are joined together.
Auto will automatically determine which conference is ‘master’ and which
conference(s) are ‘slave’. The ‘master’ conference will have control over the video
layout. When left in ‘Auto’, the conference dialing in to the other conferences,
will become the ‘master’.
Master should be used when this conference is the one controlling the video
layout for the whole conference. It is not recommended to have more than one
‘master’ in a conference.
Slave should be used when another conference manually has been assigned
‘master’. The slave will be forced to Voice Switched mode.
Max Call Duration Determines the maximum duration of the conference and will automatically
terminate the conference when the specified ‘Max Call Duration’ has been
reached. 10 minutes, 5 minutes and one minute prior to this, a warning will be
displayed to all the video participants in this conference, indicating the remaining
time. The conference administrator can extended the time. The timer for the max
call duration will not begin until the first participant is connected.
