Thirty-Four Megabit Four-Channel Multiplexer

Abstract

A four-channel high speed multiplexer/rate converter has been designed to permit the Digital European Backbone (DEB) system to utilize Conference of European Post and Telecommunications Administration (CEPT) Level 3 transmission facilities. The multiplexer combines two mission bit stream data channels each at 12.928 Mb/s, a data channel at 2.048 Mb/s, and a service channel bit stream at 192 kb/s into a composite data stream at 34.368 Mb/s. All data clocks can be asynchronous, since bit stuffing is employed. A demultiplexer that performs the inverse function is part of the full-duplex system. A design approach that easily adapts to other data rates and frame formats is used. This report describes the theory and operation of the prototype equipment. Keywords include: DCS(Defense Communications Systems; DEB(Digital European Backbone).
