Abstract
A digital subscriber communications system for transmitting voice and data information is disclosed. The signal transmissions, on any suitable medium, are in an optimized sixteen bit per frame format with a framing bit in each frame. The framing bit is detected with unique circuitry and used to phase a master synchronization signal for decoding the information transmitted.
