Table 4-16: ISDN/ATM/MPI/T1-CAS Participant - Advanced
Field/Option Description
Aggregation Select the aggregation method for ISDN/ATM/MPI video
participants:
• Auto - Connects participants to the conference
according to their endpoint capabilities. When
connecting to the conference, the endpoint and the
MCU exchange capabilities information. During this
exchange, the MCU identifies the aggregation mode
used and connects the endpoint accordingly.
• H221 - The standard communication protocol, in which
a different number is assigned to each channel. When
connecting the participant to the conference (Dial-out),
each of these numbers are dialed.
• Bonding - A communication protocol that aggregates
two to thirty 64 Kbps B channels, to act as one large
bandwidth channel. If this option is enabled, set the
Connection Type in the Identification tab to Dial-out
and enter the Phone number in the Bonding Phone
Number field.
• Multi-Rate - A communication protocol in which
channels are aggregated to form one dedicated line.
The MGC Manager currently supports aggregation of 6
channels to form one line rate of 384 Kbps (64 X
6=384). In such a case, the network ensures that all six
channels are synchronized and there are no intervals
between the arrivals of the data packets.
Number of
Channels
Indicates the number of channels used for a video ISDN/
ATM/MPI connection.
Select Auto to use the conference’s Line Rate setting.
This is also the mode recommended for ATM connections.
If the participant’s setting is different from the conference
setting, select the appropriate number of channels. During
an On Going Conference this setting may be disabled.
