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.

Conference Configuration
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.

TANDBERG MCU
Using the MCU
Legacy Mode When connecting older videoconferencing endpoints to the MCU, problems can
occur since older equipment sometimes do not handle modern capabilities.
When selected, some capabilities are not being sent from the MCU. Please refer
to the software release document for more information.
Floor to Full Screen This function only applies for the Continuous Presence 5+1 and 7+1 layout.
When selected, the participant requesting the floor, will be shown in full screen
to all the other video participants, regardless of current speaker. The same will
happen if the conference administrator ‘Assign Floor’ to a site.
When unselected, the participant requesting the floor, will be shown in the larger
quadrant of the 5+1 or 7+1 layout.
Billing Code When defining a conference, a specific billing code can be assigned to it. All
calls in this conference will be associated with this billing code. Management
tools, such as the TANDBERG Management Suite, can then use it for billing
purposes.
Video
Picture Mode Defines the picture layout for the conference.
Auto (Best ImpressionTF) will automatically select Enhanced CP (see below).
Voice Switched will show the current speaker in full screen to all the other
participants, regardless of how many participants in the conference. Current
speaker will see the previous speaker.
Enhanced CP will automatically select the most suitable picture layouts
depending on the number of video participants in the conference. For up to two
video participants, both sites will receive a full screen view of the far end. For
three to six video participants, the Continuous Presence 5+1 mode is used. For
seven and more participants, the Continuous Presence 7+1 mode is used.
Traditional CP will automatically select between Continuous Presence 4 mode,
Continuous Presence 9 mode and Continuous Presence 16 mode. For up to two
video participants, both sites will receive a full screen view of the far end. For up
to four video participants, the Continuous Presence 4 mode is used. For five and
up to nine, the Continuous Presence 9 mode is used. For ten and more
participants, the Continuous Presence 16 mode is used.
TANDBERG MCU
21
Using the MCU
Continuous Presence 4 will split the screen into four equal quadrants where
each participants is shown in one quadrant. If there more than four video
participants, the last four speakers will be shown. With less than four video
participants, the ‘empty’ quadrants will be black.
Continuous Presence 5+1 will split the screen into one larger quadrant and five
smaller quadrants where each participant is shown in one quadrant. The current
speaker will be shown in the larger quadrant to all other participants. Current
speaker will see the previous speaker in the larger quadrant. If there are more
than six video participants, the last six speakers will be shown. With less than
six video participants, the ‘empty’ quadrants will be black.
Continuous Presence 7+1 will split the screen into one larger quadrant and
seven smaller quadrants where each participant is shown in one quadrant. The
current speaker will be shown in the larger quadrant to all other participants.
Current speaker will see the previous speaker in the larger quadrant. If there are
more than eight video participants, the last eight speakers will be shown. With
less than eight video participants, the ‘empty’ quadrants will be black.
Continuous Presence 9 will split the screen into nine equal quadrants where
each participants is shown in one quadrant. If there more than nine video
participants, the last nine speakers will be shown. With less than nine video
participants, the ‘empty’ quadrants will be black.
Continuous Presence 16 will split the screen into sixteen equal quadrants
where each participants is shown in one quadrant. With less than sixteen video
participants, the ‘empty’ quadrants will be black.
Video Format Defines the video format used in the Continuous Presence mode.
Auto (Best ImpressionTF) will automatically select the most suitable video
format depending on the Picture mode used in the conference. In Voice
Switched and Continuous Presence 4 mode, the MCU will select ‘Motion (CIF)’
displaying up to 30 frames per second (fps). In Continuous Presence 5+1, 7+1,
9 and 16 mode, the MCU will select ‘Motion (CIF)’ if the call rate is below 256
kbps and ‘Sharpness (4CIF)’ when the call rate is 256 kbps or higher.
Sharpness (4CIF) will prioritize crisp and clear picture and transmit the highest
common format, preferably H.263 4CIF.
22
TANDBERG MCU
Using the MCU
Motion (CIF) will prioritize motion and show up to 30 fps in CIF resolution and
transmit the highest common format, preferably H.263 CIF.
In Voice Switched mode or Continuous Presence 4 mode, with H.264 enabled
and only one conference active, the MCU will prioritize H.264 CIF as the highest
common format.
Video Custom Formats Custom formats such as SIF and VGA resolutions are supported when the
‘Video Custom Format’ is selected. It allows true resolution to be maintained,
rather than being scaled to another format. This is of particular benefit to users of
NTSC and VGA resolutions, ensuring that their images are not scaled to fit with
the PAL standard.
DuoVideo & P+C The MCU supports DuoVideoTF on both ISDN and IP, and People+ContentTM on
ISDN. When unselected, no DuoVideoTF or People+ContentTM capabilities will be
transmitted.
Audio
Audio Levelling (AGC) Ensures that all participants receive the same audio level from all other
participants, regardless of the levels transmitted.
When selected, the MCU 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. As
a result, some of the participants are harder to hear than others. The Audio
Levelling corrects this problem by automatically increasing the microphone
levels when “quiet” or “distant” people speak, and by decreasing the microphone
levels when “louder” people speak.
Telephone Noise Suppression Attenuates the noise which normally is introduced when adding mobile phones
to a conference. The background noise normally heard when the telephone
participant is not speaking will be attenuated.
Allow G.728 The MCU supports high quality audio even on low call rate. On low call rate the

Security
Password This setting can be used to ensure that only authorized participants are able to
join the conference. The password entered in this field, will be the password a
participant must enter to join the conference. This password can only contain
digits.
When dialing into a password protected conference, the participant is met with
the ‘Password Enquiry’ screen and sound, asking the participant to enter a
password. This can be performed via a menu generated by the videoconferencing
system (H.243 Password) or via DTMF (telephone) tones. Until the correct
password is entered, the participant will not be able to hear or see any of the
other participants. After entering the correct password and confirming (typically
by pressing ‘OK’), the participant will join the conference. When using DTMF
tones, the MCU will automatically accept the password without having to press a
confirmation key.
Should the password be incorrect, the participant is met with the ‘Password
Incorrect’ screen and after a few seconds, the ‘Password Enquiry’ screen and
sound appear again. If the participant enters a wrong password three times, the
participant will be disconnected.
If no password is entered in this field, participants can join the conference
without entering a password.
Encryption The MCU supports Secure conferenceTF. When selected, all participants in the
conference must support at least standard DES encryption (available on all
TANDBERG endpoints using software version B4.0 or later). Participants not
supporting encryption will be shown the ‘Encryption Required’ screen for 60
seconds before they are disconnected from the conference.
IN A SECURE CONFERENCE, THERE IS NO SUPPORT FOR

PRI Alarms
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.

MCU Features
Experience has shown that new standardized features might cause interoperability problems between legacy video
conferencing products. If you disable features on this page, the MCU can be used as a filter to ensure
interoperability with legacy products.
To configure the MCU features, open ‘Features’ as shown in the figure below.
Video
Enable H.264 Allows H.264 video capabilities to be transmitted through the MCU. When disabled no H.264
video capabilities will be transmitted.
H.264 is supported in Voice Switched conferences and conferences with Continuous Presence 4
layout.
H.264 will be disabled if not supported by the video participants, if Duo Video is active, if more
than one conference is active on the MCU or if Continuous Presence 5+1, Continuous Presence
7+1, Continuous Presence 9 or Continuous Presence 16 is selected.
Network
Enable H.323 Allows IP participants in a conference. When disabled no H.323 traffic is allowed.
Save
Press ‘Save’ to activate the new settings.

Appendix 3: Capacity
MCU Capacity - calculation
The total capacity in the MCU is defined by the following rules:
1) Software version defines maximum number of sites:
8+8 -> Maximum 8 video sites and maximum 8 telephones
16+16 -> Maximum 16 video sites and maximum 16 telephones
2) The total system bandwidth (ISDN/IP) is 7680 kbps (120x64kbps) regardless of software version.
3) In addition, each call has a weight depending on bandwidth/encryption:
Bandwidth Teleph. 64 128 192 256 3 20 38 4 512 768 1152 1472 1920
Non-encr. 11 37 40 41 42 44 46 54 62 80 88 110
Encrypted N/A 53 59 60 61 68 73 84 111 N/A N/A N/A
The sum of the call weights cannot exceed 845. Users will be prevented from setting up calls that exceeds this limit.
Example:
If the MCU has made 6 calls at 768, 4 calls at 384, and 4 encrypted calls at 192 the calculation will be:
6x62 + 4x46 + 4x60 = 372 + 184 + 240 = 796. Since 796 is less than 845, this will be possible.
MCU Capacity – typical scenarios (16 video sites and 16 telephony calls option)
Below some typical capacity scenarios are listed. They can be derived by the calculation above:
Bandwidth Non-encrypted Encrypted
128 kbps 16 +16* 14
256 kbps 16+15 13
384 kbps 16+9 11
512 kbps 15+0** 10
768 kbps 10+0** 7
1472 kbps (1.5Mbps) 5+5 N/A
1920 kbps (2Mbps) 4+0** N/A
* 16+16 indicates 16 video sites and 16 telephones.
** Limited by the maximum capacity 7680 kbps, see 2) above.
Cascaded Conference Capacity
Up to seventeen MCUs (one master and up to sixteen slaves) can be cascaded together in one big conference, giving a
total number of 240 participants.
