ABSTRACT:
Providing a high-speed data service and voice service in a transmission system employing two binary, one quarternary (2B1Q) modulation/demodulation, using a high-speed data service remote terminal, a plurality of user data service and voice service terminals, and a multi-rate digital subscriber line (MDSL) terminal connected to the remote terminal through a twisted pair line, and to the user terminals. During downstream voice service, the remote terminal assembles and transmits an high bit rate digital subscriber line (HDSL) frame by including signaling signals for the voice service and signal processing mode information in a user-defined interval of the high bit rate digital subscriber line frame, to the multi-rate digital subscriber line terminal through the twisted pair line. During upstream voice service, the remote terminal receives the high bit rate digital subscriber line frame and transmits the signaling signals received to an exchange.
