Traffic Service Position System No. 1B: Capacity and reliability evaluation

Abstract

This paper describes the prediction and evaluation of the call-processing capacity and reliability resulting from use of the 3B20 Duplex (3B20D) Processor in the Traffic Service Position System No. 1B (TSPS No. 1B). The call-processing capacity was predicted using a processor real-time model whose parameter values were determined by laboratory and test-site measurements. The system reliability was predicted using Markov modeling techniques. Performing an evaluation during TSPS No. 1B development provided a means for monitoring progress toward meeting the capacity and reliability objectives.
