Abstract
The arrangement is for controlling speech communication in a communications exchange. The speech transmission is handled by a switchblock composed of a number of digital switching modules interconnected by a plurality of wire connections, and requiring the speech signals to be accompanied by bit and frame clock references to allow a receiving module to align the incoming data to its clock reference. The wire connections which carry frame synchronization information also carry control data which is bit interleaved with the frame synchronization information. Circuit means is provided which receives the bit interleaved frame synchronization information and control data, and demultiplexes the frame synchronization and control data to provide a retimed control data signal for use at the receiving module.
