ABSTRACT:
A multiplexing communications system comprising a first terminal means for transmitting and receiving user digitized data, a second terminal means for transmitting and receiving the user digitized data, and a communications link means for conveying the user digitized data in either direction between the first terminal means and the second terminal means. The first terminal means maintains a copy of digital control data which is necessary for controlling the second terminal means. The first terminal means has first download means for transmitting this digital control data to the second terminal means via the communications link means. The second terminal means contains a memory means for storing the digital control data, and control means for controlling the second terminal means during its normal transmitting and receiving operations. The control means requires that the digital control data be accessible from the memory means. The second terminal means also contains a second download means for receiving the digital control data from the first download means via the communications link means.
