60 Capacity
Use
CCS value and obtain the number of PSTN trunks (in the cell to the left of
the CCS number). If the CCS value is between two values in the trunks
column, choose the higher number of trunks. For trunk traffic greater than
6068 CCS, allow 30.34 CCS per trunk.
Multiply the number of PSTN trunks by two to obtain the number of SIP
Access Ports required.
