Table 29
provides a summary of call usage rates, which can be mapped to a table of TDM
usage rates and media processing usage rates by using the information in
TDM and Media Processing resource requirements
and Media Processing resource requirements
PN in Site 1, one in Site 2, and two G350 Media Gateways in Site 3. Under this assumption,
which will be assessed shortly, all calls between circuit-switched endpoints in Sites 1 and 2 are
assumed to be intra-Port Network. A minimum of two G350 Media Gateways is required to
house the 36 analog telephones in Site 3. The results of this exercise are shown in
Table 30: TDM and Media Processing usages (Erlangs) for Example 5: TDM and media
processing
usage.
