Abstract:

This report describes a programmable transmission control unit which is attached to an IBM System360 Model 67 machine operated in a timeshared environment. Called the Data Concentrator, this device provides service for ATT teletype equipment, IBM typewriter terminal equipment, and remotely located computer equipment interconnected with serial-synchronous transmission data sets. The data Concentrator is constructed of several different kinds of line adapters which connect on one hand to all types of ATT data sets available for use on the switched-network, and on the other to a modified Digital Equipment Corporation PDP-8 computer. Connection is made between the System360 multiplex channel and the PDP-8 by means of a special interface which provides a direct connection to the control lines emanating from the multiplex channel and presents a behavior compatible with other IBM transmission control units. The programmable nature of the Data Concentrator provides an unusually rich variety in transmission protocol and operational modes for its attached terminal equipment yet with minimal modifications to extant System360 control programs.
