Abstract
In planning investment to meet growth in demand on the telephone system, it is highly desirable to be able to predict how well proposed configurations of exchange equipment will meet specified future demand. The methods developed for this purpose form the body of telephone traffic theory. This paper describes approximate queueing theoretic methods used in the analysis of queueing delay in the TXK3 crossbar exchange, and compares the results obtained from these models with results from simulation study. The methods have already been used in the analysis of exchanges but, in the author's view, are not yet fully validated.
