The possibility to operate a modem receiver with external timing is discussed. External timing means that the timing of signal-processing and digital-interface functions of a receiver is not derived from the analog signal received, but comes from a source external to the receiver. External receiver timing is useful, e.g., when modem receivers operate back-to-back with modem transmitters. For certain configurations of communication networks it is necessary that modem receivers and transmitters operate back-to-back. One example is when the outputs of several lower-speed modem receivers are to be concentrated at some network location in the transmitter of another channelized higher-speed modem.
