摘要：A method and apparatus for converting an analog voice channel signal and a 4-wire digital signal into a single 2-wire digital signal which can be transferred over a singletwisted pair line. In one aspect, the method comprises the steps of converting the analogvoice channel signal into a first binary signal, converting the 4-wire digital signal into a

second binary signal, combining the first binary signal and the second binary signal into ahigher rate binary signal, and converting the higher rate binary signal into a 2-wire digitalsignal which can be transmitted to another location over a single twisted pair line. Inanother aspect, the method comprises the steps of converting a 2-wire digital signal to ahigher rate binary signal, separating a first binary signal and a second binary signal fromthe higher rate binary signal and converting the first binary signal into an analog voicechannel signal, and converting the second binary signal into a 4-wire digital signal. Theapparatus includes an easily installed voice plus digital data remote terminal and voiceplus digital data central office terminal. The apparatus can provide a 3-to-1 pair gain bymultiplexing signals representing the analog voice telephone signals and 4-wire digitaldata signals.
