Higher order digital transmission system including a multiplexer and a demultiplexer.

摘要

Higher order digital transmission system including a multiplexer having N parallel inputs to which tributary input signal streams are applied, and a demultiplexer having N parallel outputs from which the tributary signal streams are taken. The signal processing operations, such as scrambling, justifying, line coding, error monitoring and word synchronization are effected before the multiplexer and after the demultiplexer.
