Abstract
Abstract Digital carrier channels and switching systems in a telecommunications facility may be used to transmit a high-speed data signal between an originating end and a terminating end. At the originating end, the high-speed data signal is distributed either bit-by-bit or sample-by-sample and sequentially to a predetermined plurality of lower speed channels. At the terminating end, the lower speed channels are collated to reconstruct the original high-speed data signal, using submessage sequence identifying signals.
