Digital communication signal transmission control system

摘要

The control system is used for transmission of digital communication signals of two types between a pair of communication devices (K1,K2) linked via a TDM transmission medium (ZL) with a number of time channels, each divided into a number of sub-channels. A given number of sub-channels of each time channel are reserved for digital signals of a given type, with control data transmitted upon a variation in the assignment of the sub-channels, for indicating the signal type assigned to each sub-channel, for synchronising both the communication devices.
