ABSTRACT:
A digital signal distributor for time division multiplex signals having the same frame format and for discrete channel signals has frame adaptors for synchronizing and storing the time division multiplex signals, and memories for the discrete channel signals, the frame adaptors and memories being provided following the inputs for the time division multiplex channels. The circuit further includes a distributor unit having an operator interface connected to the frame adaptors and the memories by first bus lines and first discrete lines. A clock pulse generator controls cyclical feeding of the stored code words into the first bus and first discrete lines. Second bus and second discrete lines are connected to an output of the distributor unit and transmit the time division multiplex output signals and the discrete signals to outputs of the circuit.
