Dynamic Call Admission Control
In order to manage the flow of calls and voice data on the G350 most efficiently, the Media Gateway
Controller must have real-time information about the network topology and currently available
bandwidth. Without this, changes to the network structure, such as switching over to a backup line, can
cause the network to become overloaded with voice data. The MGC, unaware of the switchover,
continues to admit calls at the same volume, causing network congestion. Using the Dynamic CAC (Call
Admission Control) feature, the G350 can provide the MGC with up-to-date information on the
bandwidth available for voice data.
By default, G350 interfaces do not participate in Dynamic CAC. However, it is highly recommended to
enable Dynamic CAC on the G350's interfaces. If users report problems with long delays, jitter, and loss
of calls, enable Dynamic CAC to provide greater link reliability and robustness.

Enabling Dynamic CAC on the G350

Use the
dynamic-cac
on each interface responsible for providing call bandwidth. If Dynamic CAC is enabled on more than one
interface, specify an activation priority for each interface. The BBL (Bearer Bandwidth Limit) is reported
as the BBL of the interface with the highest activation priority.
The dynamic-cac command has the following syntax:
dynamic-cac bbl
