SERVICE INTEGRATED TRANSMISSION SYSTEM

摘要

A method of transmitting signals of different information rates between a subscriber and a central exchange of a service integrated system operating in time multiplex wherein the signals to be transmitted are combined at the transmitting end by means of multiplexers and the transmitted signals are recovered at the receiving end by means of demultiplexers. The frequency of the time multiplex frame, i.e. the frame frequency, is selected to be equal to the smallest information rate of the signals to be transmitted and one information unit of the signal having the smallest information rate is transmitted per frame.
