Starting with release 3.1 of Communication Manager, the TN2602AP IP Media Resource 320 can be duplicated to provide critical bearer reliability for IP-connected port networks.

If more than one PN had been required in a particular site, intrasite calls between circuit-switched endpoints in that site would have contributed toward media processing usage because inter-Port Network calls between circuit-switched endpoints traverse an IP network. Since only one PN is required in each site in this example, the media-processing usage for calls between circuit-switched endpoints is zero in each site, as indicated in Table 34.

Processing occupancy

The Busy Hour Call Attempt (BHCA) rate of a system is the total number of calls that are attempted within that system, during its busy hour. This is distinct from the Busy Hour Call Completion (BHCC) rate of a system, which counts only those calls that have actually been completed. The call capacity of a system refers to its BHCC rate.

In Communication Manager products, server occupancy (or processor occupancy, as applicable) can be broken down into three categories: static occupancy, Call Processing (CP) occupancy, and system management (SM) occupancy. The static component refers to keep-alive processes, the CP component refers to processes that are required to set up and tear down calls (as well as vectoring operations, in the case of call centers), and the SM component refers to background maintenance operations and system audits. In theory, static occupancy is a fixed overhead, and CP occupancy is directly proportional to the call rate. SM
