Figure 59: Inter-site TDM and Media Processing resource requirements
In Figure 59: Inter-site TDM and Media Processing resource
presented on an endpoint-by-endpoint basis. For example, according to
TDM and Media Processing resource
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
Processing resource requirements
Processing resource requirements
matrices will be further expanded.
