Adaptive Network Bandwidth Management 117
• Adaptive Network Bandwidth Management parameters are configured
on the main office only and must not be configured at the branch offices.
Configuring Adaptive Network Bandwidth Management
The following is a summary of the tasks necessary to configure Adaptive
Network Bandwidth Management in the network.
1. Enable the Call Admission Control (CAC) package.
2. Configure CAC in Element Manager or LD 117:
a. Configure the VPNI on the main office and branch offices.
b. Configure both the main office and branch office zones at the main
office.
c. Configure the branch office zone on the SRG.
d. Configure the interzone and intrazone bandwidth limits at the main
office and SRG.
e. Enable Adaptive Network Bandwidth Management for the zones
on the main office Call Server.
f. If required, alter the Adaptive Network Bandwidth Management
parameters in keeping with the information in
"Advanced
Configuration Notes" (page 117) below.
3. Tandem the outbound branch office calls by configuring the NRS.
4. Tandem the inbound branch office calls by creating a dialing plan which
routes all calls destined for the branch office through the main office.
Advanced Configuration Notes
1. The default values for Cpl, Cj, Cd, Cr and CQos can be increased to
increase the response time for Sliding Maximum changes. However,
increasing them can cause the Sliding Maximum to temporarily decrease
to a lower value then necessary, resulting in the needless blocking of
interzone calls.
2. Increasing the value of ZQRT will increase the speed at which the
Sliding Maximum increases. The same effect can be achieved by
decreasing ZQRTI. However, changing these values can cause the
Sliding maximum to oscillate until the network degradation is removed.
Configuration using Element Manager
Element Manager can be used to enable and configure the feature.
