CHAPTER 1. Voice Feature
Local CAC
Local CAC mechanisms function on the outgoing Ubigate iBG2016 system.
The CAC decision is based on nodal information such as the state of the Max.
Calls.
The Ubigate iBG2016 system provides Call Admission Control based on
Maximum Call Number per System Wide. The Call Admission Control Based
on Max. Call feature permits the Ubigate iBG2016 system to deny incoming
calls exceeding a preconfigured threshold, permitting the selection of a system
max. call value. This feature helps ensure the quality of service of existing
calls and reliability of system processes by preventing system overload caused
by excessive incoming calls. The feature rejects new calls, with minor
disruption to system users. The administrator of the Ubigate iBG2016 system
sets a threshold at which denial of new calls occurs.
The Ubigate iBG2016 system provide Call Admission Control based on
Maximum Call Number per Dial-Peer.
The Ubigate iBG2016 system provide Call Admission Control based on
Physical DS0 Limitation.
Resource-based CAC
Resource based CAC mechanisms function on the outgoing Ubigate iBG2016
system. The CAC decision is based on nodal information such as the state of
the CPU, memory and DSP channels load level.
The Ubigate iBG2016 system provides Call Admission Control based on CPU
utilization. The Call Admission Control Based on CPU Utilization feature
permits the Ubigate iBG2016 system to deny incoming calls exceeding a
preconfigured threshold, permitting the selection of a system CPU load level
value. This feature helps ensure the quality of service of existing calls and
reliability of system processes by preventing system overload caused by
excessive incoming calls. The feature rejects new calls, with minor disruption
to system users. The administrator of the Ubigate iBG2016 system sets a
threshold at which denial of new calls occurs. This CPU load threshold may
be set anywhere from 20 to 90%.
