Abstract:
An apparatus for converting analog voice channel signals and 4-wire digital signals into a single signal which can be transferred over a single twisted pair line, comprising:means for receiving a first analog voice channel signal;means for receiving a second analog voice channel signal;means for receiving a first 4-wire digital signal;means for receiving a second 4-wire digital signal;means for converting the first analog voice channel signal and the second analog voice channel signal into a first binary signal;means for converting the first 4-wire digital signal and the second 4-wire digital signal into a second binary signal;means for combining the first binary signal and the second binary signal into a higher rate binary signal;means for converting the higher rate binary signal into a 2-wire digital signal; andmeans for transferring the 2-wire digital signal to a twisted pair line.
