ABSTRACT:
A switching system for switching-through in time-division multiplex broadcast connections and point-to-point connections. In prior art broadcast switching systems the incoming (transmitter) channels are fed with multiplicity into the switching system and distributed there in accordance with a distribution algorithm. This multiple feed-in is effected in the switching system of the invention in a time-division multiplex switching stage divided into parallel units as a result of which the switching rate of this stage does not become excessively high. In order to realise this parallel distribution of this time-division switching stage a certain restriction of the distribution algorithm must be tolerated.
It has been found that the switching system thus obtained is suitable for multislot connections, whilst it can also be rendered suitable for point-to-point connections by slightly extending it.
