ABSTRACT:
A switching unit for the selective transfer of bytes concurrently arriving in successive time slots over eight incoming signal paths to as many outgoing signal paths with intervening temporal and/or spatial transposition comprises a byte memory, loaded by way of a series/parallel converter and read out by way of a parallel/series converter, under the control of a routing memory dialoguing via a logic network with a microprocessor. The latter, through instructions sent to the logic network, may command the blocking of the readout from the byte memory onto an outgoing path during a given time slot, the insertion of a particular byte into such a time slot, or the transfer of selected bytes from either memory to the microprocessor itself. In particular, bytes from the first time slots of PCM frames arriving over selected signal paths can be so extracted from diagnostic purposes.
