A Computer Aided Tool for the Analysis of Telephone Traffic on High-Usage Routes

Abstract

The investigation of telephone traffic on high-usage routes is one important problem in the evaluation of the busy-hour service of telephone exchanges. In this paper, the acceptable level of offered traffic on a high-usage route is considered to be that which results in a specified last trunk occupancy assuming sequential hunting. Using teletraffic analysis, a mathematical formula that represents the case is derived; and a computer program written in Pascal is described. The application of the program is demonstrated by means of two examples; the first is related to the development of traffic tables, and the second is concerned with the investigation of high-usage routes on some telephone exchanges in practical use.
