On Distributed Communications Series

VIII. The Multiplexing Station


This Memorandum is one in a series of eleven RAND Memoranda detailing the Distributed Adaptive Message Block Network, a proposed digital data communications system based on a distributed network concept, as presented in Vol. I in the series.[1] Various other items in the series deal with specific features of the concept, results of experimental modelings, engineering design considerations, and background and future implications.

The series, entitled On Distributed Communications, is a part of The RAND Corporation's continuing program of research under U.S. Air Force Project RAND, and is related to research in the field of command and control and in governmental and military planning and policy making.

The present Memorandum, the eighth in the series, describes the Multiplexing Stations that connect subscribers to Switching Nodes (detailed in Vol. VII) of the proposed broadband distributed network. The description is presented in engineering detail, showing how the Station is able to process simultaneously traffic from up to 1024 separate users sending a mixture of start-stop teletype signals and synchronous signals at various rates.

The Memorandum will be of principal interest to those concerned with the details of design and operation of the proposed network, and also of some interest to communications designers and planners concerned with the transmission of digital data.
