In addition, 37% of intercom calls that are generated in Site 1 are generated by circuit-switched
stations, and 69% of those calls are terminated by IP stations. Since 69% of 37% is 25.5%,
25.5% of Site 1 to Site 2 intercom calls are circuit-switched station to IP station. Finally, 37% of
intercom calls that are generated in Site 1 are generated by circuit-switched stations, and 31%
of those calls are terminated by circuit-switched stations. Since 31% of 37% is 11.5%, 11.5% of
Site 1 to Site 2 intercom calls are circuit-switched station to circuit-switched station.
So, since 43.5% of Site 1 to Site 2 intercom calls are IP station to IP station, Site 1 IP station to
Site 2 IP station CUR is 43.5% of the 12 Erlangs of overall Site 1 to Site 2 intercom CUR, or 5.2
Erlangs. Similarly, the Site 1 IP station to Site 2 circuit-switched station CUR is equal to 19.5%
of 12 Erlangs, or 2.3 Erlangs, and the Site 1 circuit-switched station to Site 2 IP station CUR is
equal to 25.5% of 12 Erlangs, or 3.1 Erlangs. Finally, the Site 1 circuit-switched station to Site 2
circuit-switched station CUR is 11.5% of 12 Erlangs, or 1.4 Erlangs.
The values for the remaining COI cells that correspond to intercom traffic for this example are
calculated in a similar manner.
Table 27: COI matrix for Example 4: Expanded COI matrices
(intercom CUR values only)
