Traffic engineering
In addition, 37% of intercom calls that are generated in Site 1 are generated by
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
The values for the remaining COI cells that correspond to intercom traffic for this example are calculated in a similar manner. Table 31: COI matrix for Example 4: Expanded COI matrices (intercom CUR values only) summarizes the results of that exercise:
