Frame restructuring section point for digitally multiplexed follow in the time-division multiplex of digital secondary channels of different bit rates.

摘要

This interface of restructuring of frames for digital bit streams multiplexed by time multiplexing of digital tributary with different flow rates in a hierarchy of multiplexed synchronous at different levels of which are constituted of the entities called containers and of the entities called units of multiplexing, comprises means of extraction of the incoming frames of the signals of containers to be treated, and means for the constitution and multiplexing of the frames restructured cut into sections of the same length, of units of multiplexing restructured by insertion of these signals, as well as signals indexing and justification for carrying out an adjustment of their extraction rates and of insertion, at locations elementary for the same container to be treated, have to the inside of each section of a frame restructured of the rows are defined with respect to the start of the cross section, these rows are invariable of a section of the frame to another and from one frame to another and each set of locations of the same rank of the sections of the frames restructured being assigned to at most a multiplexing unit restructured.
