A repeater having first and second communication terminals that receives signals at either of the terminals and transmits signals responsive to the received signals at the other of the terminals, comprising: a first signal processor that receives V.90 analogue data signals from the first terminal and generates bit streams responsive thereto that accurately reproduce the data in the analogue signals; a second signal processor; and a communication channel linking the first and second signal processors wherein the second signal processor receives the bit streams generated by the first signal processor via the communication channel and transmits V.90 PCM octets responsive thereto via the second terminal.
