Global - CAC - Shared CAC Limits Pool

In this section:

Use the Shared CAC Limits Pool window to configure general parameters for a shared CAC limits pool object. A shared CAC-limits pool is a global resource that helps define define multi-level Call Admission Control (CAC) policy by linking trunk groups together in a pyramid-type structure. Trunk groups are assigned to shared CAC-limits pools, and sets of CAC-limits pools can be assigned a parent to create a higher-level shared CAC-limit pool. Refer to Shared CAC-Limits Pool - CLI for more information on this capability.

(Refer to SBC Provisioning Limits for Shared CAC-Limits Pool provisioning limitations)

Shared CAC Limits Pool

Parameter	Description
Name	Specifies the name for this shared CAC-Limits pool.
Parent Shared CAC Limits Pool Name	Specifies an existing shared CAC-Limits pool to be the parent of this CAC-Limits pool.
Call Limit	Specifies the total number of concurrent calls (either ingress or egress) allowed. The value range from 0 - 2000000000 calls.
Call Limit Threshold	Specifies the concurrent calls notification threshold. The value range from 0 - 100%.
Bandwidth Limit	Specifies the total media bandwidth limit in K bits/second. The value range from 0 - 2000000000 k bits/second

Emergency Oversubscription	Specifies the oversubscription of resources (As percentage) that is allowed for emergency calls. When the baseline call limit and the bandwidth limit are reached, normal calls will be blocked and only emergency calls will be allowed up to this additional percentage. The value range from 0 - 100%.
Registration Limit	Specifies the total number of concurrent SIP registrations allowed. The value range from 0 - 2000000000 registrations.
Subscription Limit	Specifies the total number of concurrent SIP subscriptions allowed. The value range from 0 - 2000000000 subscriptions.
