24 Description
Bandwidth Management Overview
For a complete overview of Bandwidth Management, see the Converging
the Data Network with VoIP (NN43001-260) and for details on configuration,
see
"Bandwidth Management" (page 95) .
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.
ATTENTION
Throughout this document, the term zone is defined as a Bandwidth Management
Zone, not an NRS (H.323 Gatekeeper) Zone. See
"Bandwidth Management"
(page 95) .
Time of Day
Because the SRG IP Phones, in Normal Mode, receive their clock
information from the main office, which may be located in a different time
zone, the main office must be able to provide a different time of day for
these phones.
