Nortel Networks SRG 50 NN43001-307 - Manual (Page 102)

102 Bandwidth Management
2. Branch office (MG 1000B and SRG) Call Servers must be configured
with the same VPNI as that of the main office Call Server with which
they register.
3. Nortel recommends that all the endpoints on a Call Server (IP Phones
and Voice Gateway Media Cards) be configured with the same Zone
number.
4. Virtual Trunks must be configured with a different Zone number than
the endpoints.
Network Planning
Before configuring Bandwidth Management in a CS 1000 network, follow
these steps:
Step Action
1 Choose unique VPNI for all Call Servers in the network.
2 Choose unique Bandwidth Zone numbers for all Call Servers in
the network. These are used when configuring the endpoints
(telephones and gateways) on the Call Server.
3 Choose unique Bandwidth Zone numbers for the Virtual Trunks in
the network.
4 Choose the codecs that will be enabled on each Call Server.
5 Identify what the interzone codec strategy will be (BB-Best
Bandwidth or BQ-Best Quality) for each zone in the network.
6 Identify what the intrazone codec strategy will be (BB-Best
Bandwidth or BQ-Best Quality) for each zone in the network.
7 Calculate the bandwidth available for intrazone calls for each zone
in the network.
8 Calculate the bandwidth available for interzone calls for each zone
in the network.
9 Calculate the bandwidth available for intrazone calls
—End—
Enabling codecs
In Element Manager, select the codecs that will be enabled for calls on the
Call Server, and define the associated parameters, such as payload size.
