Call volume (telecommunications)
In telecommunications, call volume refers to the number of telephone calls made during a certain time period. Depending on context, the phrase may refer to either the number of calls made to a specific physical area or telephone number (such as an emergency service) or the number of calls made between two or more areas (e.g. cities).
Calls Per Second or CPS refers to how many telephone calls can be handled in a second. CPS is one measure of the performance of Switching systems. It helps in estimating Busy-hour call attempts (BHCA) and Busy-hour call completion (BHCC) of Switching systems.
Perhaps the simplest formula used to forecast call volume is the linear equation
where y is the expected call volume, x is time, and m and b are constants.
where C is the number of expected calls between two cities (during one day), P1 is the population of the first city (in thousands), P2 is the population of the other city (also in thousands), and d is the distance between them (units unclear in the book, but probably miles).
