摘要: A method and related apparatus for concurrent transmission reception of at least one analog voice telephone signal ISDN service between a first location second over single twisted pair using digitally encoded that is selected from the group consisting 2B1Q 4B3T signals. The further includes steps sending line power pair, transferring to detecting non-operation thereby impose bypass lifeline provide pair. also step providing when not detected. present can 2-to-1 gain by multiplexing signals representing signal, in specific embodiment.
