Figure 57: Connectivity modes between two IP endpoints
At this point, we can quantify the TDM and media processing requirements for various call
types. Throughout this discussion, calls between two IP stations are assumed to use shuffling.
That being the case, an intrasite call between two IP endpoints requires neither TDM nor media
processing resources, beyond the completion of the initial call set-up process. Each intrasite
call between an IP endpoint and a circuit-switched endpoint (including PSTN trunks) requires
one TDM resource and one media processing resource. Each of these resources is furnished
by the PN or the Media Gateway to which the circuit-switched endpoint is administered. See
Figure 56: Examples of media streams between Avaya endpoints
on page 164 for an example.
The TDM and media processing resources that are required for each intrasite call between two
circuit-switched endpoints depends upon whether the call is intraport network or interport
network. Specifically, each intraport network call requires one TDM resource (on the port
network to which the two circuit-switched endpoints are administered), and no media
processing resources. See
Figure 56: Examples of media streams between Avaya
endpoints
on page 164 for an example. Also, assuming that IP interport network connectivity is
