As I recall, CA includes all call events that impact processor real-time. The major category is all actions required for the successfully completed call. The smaller components of CA would be mis-dial, abandoned calls, etc.

Another related topic is how real-time is assigned to a “call”. RT/ call varies with call type. A simple desk-desk call type without billing and other features would have the smallest RT demand. A call going over IXC trunk and requiring billing and other features actions would require more RT. RT is generally expressed in milliseconds/ call

Switch suppliers generally state their CA capacity by :Call Mix”: 50% POTS/ 50% Business”

Telcordias’ model for call capacity is:

[(3.6 M millisec/hour) * (max. % processor occupancy)]/(millisecond/call
