ABSTRACT:
A central switching facility is constituted by two switching networks connected to each of the connection units via two connection circuits. A connection circuit selects on a timeslot-by-timeslot basis which output network link is to be used for conveying each time slot to the connection unit. On an instruction from the switching network, a connection circuit operates, in a message mode, on one of the time slots selected from those which it processes, and it sends monitoring information to the switching network via control bits in that time slot. An instruction bit, selecting a message mode or a normal mode, is included in each frame transmitted from the switching network to a connection circuit.
