“I” denotes IP endpoint; “C” denotes circuit-switched endpoint (other than PSTN trunks);

“P” denotes PSTN trunk

In Figure 68, the usages are presented on an endpoint-by-endpoint basis. For example, according to Figure 68, an intersite call between an IP endpoint in Site 1 and a circuit-switched endpoint in Site 2 requires no TDM or media processing resources in Site 1, but does require one TDM resource and one media processing resource in Site 2.

The overall TDM usage and media processing usage for each site can be calculated from an expanded COI matrix, along with the information from Figure 67 and Figure 68. To illustrate, Example 4: Expanded COI matrices will be further expanded.
