IBM 2750 Voice and Data Switching System: System Generation and Simulation

A large number of IBM 2750 system configurations is available. Any particular 2750 system configuration runs under control of a personalized program package, and each personalized program package is generated on a remote system/360 using as input a generalized program package, written in a macro assembly language, in conjunction with a set of configuration parameters. The output of the generation process is a set of absolute binary paper tapes which are loaded directly into the 2750 system. The reliability of the personalized program package is ensured by running it under the control of a program that simulates the operation of the 2750 system. This paper describes the structure of the generalized program package and the technique used for the generation and simulation of personalized program packages.
