Abstract

Teleprocessing (TP) ports on medium and large frame computers must be functionally tested by attaching actual equipment, such as modems and terminals. Due to the varying configurations of teleprocessing ports a variety of testing equipment is necessary. The teleprocessing test device is simulated such that hardware can be configured by software to test the different ports of the 4300 series of computers, thereby eliminating the need for multiple pieces of equipment. The simulation is accomplished as follows. The block diagram shown contains the hardware that converts parallel data into serial data and vice-versa. This hardware also converts vendor transistor logic level signals into interface levels that correspond to those of the 4300 series.

Teleprocessing Simulator

Teleprocessing (TP) ports on medium and large frame computers must be functionally tested by attaching actual equipment, such as modems and terminals. Due to the varying configurations of teleprocessing ports a variety of testing equipment is necessary. The teleprocessing test device is simulated such that hardware can be configured by software to test the different ports of the 4300 series of computers, thereby eliminating the need for multiple pieces of equipment. The simulation is accomplished as follows. The block diagram shown contains the hardware that converts parallel data into serial data and vice- versa. This hardware also converts vendor transistor logic level signals into interface levels that correspond to those of the 4300 series. The microprocessor hardware is configured as an interface to a variety of teleprocessing channels. The TP simulator can be used as an aid for running the cable wrap tests on all of the teleprocessing lines. It will sense signals on the interface and will make the necessary responses, thus incorporating a software wrap instead of using a hardware wrap plug. This feature can also be used in running basic reliability, availability, serviceability (RAS) diagnostics on the External Modem Interface for the Remote Support Feature (RSF) on the 4300 series machines. The hardware can simulate the following types of interfaces: V35 (balanced current type), RS- 232 (1 = +8.5 V, 0 = -8.5 V), LOC ATT (similar to...
