Configuring Adaptive Network Bandwidth Management
The following is a summary of the tasks necessary to configure Adaptive Network Bandwidth Management in the network.
1Enable the Call Admission Control (CAC) package.
2Configure 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” below.
3Tandem the outbound branch office calls by configuring the NRS.
4Tandem 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
1The 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.
2Increasing 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.
3It may be necessary to change the notification level (ZQNL) of the Call Server so it can react to the QoS alarms. Use LD 117 to change this level.
