Number of Calls Per Second
The number of calls per second (CPS) that the system processes is one way to determine the capacity of the system. Capacity is a measurement of the volume of traffic that a network is engineered to handle. Voice networks are typically engineered to handle a target peak-load capacity, commonly measured in CPS.
You need to monitor the number of CPS for licensing purposes. In the releases before vCUSP 9.1.5, if you exceed the number of CPS, and thus the number of licenses, the system rejects calls. In vCUSP 9.1.5 and later releases, the calls continue to connect. You can also monitor the CPS to determine traffic patterns.
The system provides two graphs that display the number of CPS including the following:
-
Number of incoming CPS for the last hour
-
Number of incoming CPS for the last 72 hours
