DEVELOPMENT OF (PCM) DATA BUFFERS.

Abstract

The purpose of this project is the design and construction of four advanced development models of a low-speed and two of a high-speed converter (PCM Buffer), digitalto-digital -- each for inserting a number of digital data channels into Data I or Data II of the PCM Multiplexers TD-352( )/U or TD-353( )/U. The High-Speed Buffer (Task 1) must be capable of handling synchronous and asynchronous data; the Low-Speed unit (Task 2), synchronous data only. The manufacturing drawings for the high-speed buffer were delivered. The following work was accomplished on the low-speed buffer: (a) Logic design, including that for the Data Source Simulator, was completed. (b) Circuit design, incorporating the changes necessitated by addition of the Voice Order-Wire Facility and the Variable-Output-Rate Capability, was completed. (c) Mechanical design was completed. Fabrication and assembly is in progress. (d) All printed-circuit-card types passed preproduction tests satisfactorily.
