Evaluation of Teletype Multiplex Equipment AN/TCC-35
Abstract
A test program conducted by the USAF on the AN/TCC-35 Teletype Multiplex Equipment is described. It was possible to draw a number of conclusions based on these tests. (1) The mechanical engineering of the AN/TCC- 35 must be improved with regard to packaging of units. There is insufficient ventilation area for the test oscilloscope, and its location does not permit easy use of it for maintenance, (2) The type of relay in the Voltage-to-Current Converter is not adequate, (3) The receive channel output load now in the AN/ TCC-35 is not as reliable as a good polar signa l relay would be, (4) Tolerance of the input circuits of the Transmitter Code Converter is too narrow; it will not function with a 10% or more drop in line current, (5) Investigation of encapsulating techniques for diodes, magnetic cores, and transistors was not sufficient, and these devices do not function well in the equipment, and (6) In its present form, the AN/TCC-35 is unsuitable for integration with existing USAF radio and TTY communications equipment and with USAF security equipment used in the STRATCOM system.
