Patent ID: 6970502

Claim:
A method, comprising: providing high speed data services and voice services in a transmission system employing two binary, one quaternary modulation/demodulation, said transmission system including a remote terminal providing a high-speed data service, a plurality of user terminals including data service terminals and voice service terminals, and a multirate digital subscriber line terminal connected to said remote terminal through a twisted pair line, said multirate digital subscriber line terminal being connected to said user terminals, said voice services including upstream and downstream voice services; during said downstream voice service, assembling, in said remote terminal, a first high bit rate digital subscriber line frame by including signaling signals for said voice service and signal processing mode information in a user-defined interval of said first high bit rate digital subscriber line frame, and transmitting said assembled first high bit rate digital subscriber line frame to said multirate digital subscriber line terminal through said twisted pair line; and during said upstream voice service, receiving, in said remote terminal, a second high bit rate digital subscriber line frame and transmitting signaling signals in said received second high bit rate digital subscriber line frame to an exchange.
