Abstract
An arrangement for interfacing the originating time stage (OTS) and terminating time stage (TTS) of a time and control unit (TCU) to the space stage of T-S-T digital switching system. The space stage includes an intra-path through the space stage as well as an interpath. The interface transmits PCM samples simultaneously from the OTS to both the intra and interpaths of the space stage. PCM samples from the space stage are received by an intra buffer and an inter buffer from the intra path and inter path respectively. A TCU control memory gates and connects either the intra buffer or inter buffer to the TTS.
