Telecommunication switching system - uses TDM to connect entry ports to exit ports. uses matrix of switches and memory with record of source and destination ports

摘要

The telecommunications switching system connects a number of input lines to a number of output lines using a time division multiplexing arrangement. Each time-division multiplexed line entering the switching system is synchronised and connected to the entry ports of the switching system. There is a matrix of switches which is regulated by a control circuit, and this control circuit has a memory containing the source and destination ports, and the time slice, corresponding to each channel. This controller ensures that the appropriate switches are activated at the correct time so that each entry port is connected to the correct exit port.
