ABSTRACT:
A method and apparatus for distributing high-bandwidth and low-bandwidth voice channels is presented. An input signal is received and separated into a first low-band signal and a first high-band signal. The first low-band signal is compressed to provide a low-bandwidth channel and is used to carrying encoded voice signals (e.g. G.711). The high-band signal is also compressed to provide a high-bandwidth channel and is used to carry encoded voice signals (e.g. G.722).
