Abstract
This invention relates to a switching system for time-division multiplexed PCM channels. The system possesses essentially an incoming time-division switching device, a space-division switching device and an outgoing time-division switching device. The invention proposes to produce these time-division switching devices in the form of memories organized in pages enabling them to be manufactured in the form of hybrid monolithic integrated circuits. Application: time-division telephone switching.
