Specifies the object containing CAC-Limits that apply to a set of Trunk GroupsUse 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.
