Network Bandwidth Management
Network Bandwidth Management allows for a limit to be placed on the
amount of interzone bandwidth allowed between IP Phones in Normal Mode
at the SRG and the rest of the CS 1000 network.
As well, it allows for the selection of interzone bandwidth codecs for calls
between the IP Phones in Normal Mode and the rest of the CS 1000 network.
Adaptive Network Bandwidth Management
Adaptive Network Bandwidth Management allows the system to dynamically
react to Quality of Service (QoS) degradation and take corrective action.
Network Bandwidth Management Zones
A zone is a collection of IP Phones that:
• share similar IP bandwidth restrictions
• are geographically close to one another
• are all in the same time zone
• are all in the same PSTN dialing plan
The Network Bandwidth Management Zone is made up of the VPNI and the
zone. The VPNI of the main office and all the SRG associated with it must be
the same.
Each SRG must have its own unique zone number and configured in the main
office Call Server and the SRG.
Note: Throughout this document, the term "zone" is defined as a
Bandwidth Management Zone, not an NRS (H.323 Gatekeeper) Zone.
