CHAPTER 4.
This chapter describes system features provided by IPX-S300B.
System features are performed according to the configuration of the system, not individual
user setting.
Anonymous Call Reject
The anonymous call reject service rejects anonymous incoming trunk calls without caller
IDs.
This function can be enabled or disabled by the operator.
Call Admission Control (CAC)
Since system resources are limited, a service is required to set the maximum number of
calls at any one time. The Call Admission Control (CAC) service provided by IPX-S300B
includes CAC by call counts, CAC by location bandwidth, CAC by system resources, and
CAC by trunk call counts.
All CAC is independently operated by each node.

CAC by Call Counts
This function rejects calls that exceed the maximum call count supported by the IPX-
S300B.

CAC by System Resources
The CAC by system resources service restricts calls made in excess of the maximum
usage ratio set for the system CPU and memory.

CAC by Location Bandwidth
The CAC by location bandwidth service restricts the calls made in excess of the
bandwidth set for each location.
When calls are made between users or endpoints in different locations, the system
calculates the bandwidth based on the codec used for the calls. Any calls exceeding the
maximum bandwidth set for each location are restricted.

CAC by Trunk Call Counts
CAC by trunk call counts restricts calls when the maximum trunk call count supported
by IPX-S300B is exceeded. If you don't set the maximum inbound call or maximum
outbound call value, CAC for the trunk call (Inbound call or outbound call) does not
work.
