ABSTRACT OF THE DISCLOSURE A signal monitoring and controlling system for a time division switching system monitoring and controlling signals transferring to and from all or some of line interface equipment such as a digital trunk, analog trunk equipment, the intra-office line concentrators or remote line concentrator through a signal path. In the signal control, the signal is classified into two kinds of signals: one for cyclically controlling a state and the other for randomly controlling the same. Those signals are multi- plexed in a single time slot to control the various line interfaces. Signal time slots having different multi- frames and signal time slots with a plurality of periods are monitored depending on a signal path class thereby to reduce the number of laying cables among interframes.
