摘要： A digital transmission system employing nBmB codes in which provision is made for insertion of service and auxiliary data bits. The transmitter of the transmission system includes a series to parallel converter, register file, pulse insertion circuit, nBmB encoder and parallel to series converter. The bit rate of the parallel n bit code streams is converted to produce an additional time slot after each occurrence of a predetermined number of data bits. Service and auxiliary data bits are inserted in the additional time slots. The receiver portion of the transmission system includes a series to parallel converter, followed by an nBmB decoder, a pulse separator, a register file and a parallel to series converter. At the receiver, the mB code is converted back to an nB code from which the service and auxiliary data bits are extracted and subsequently removed.
