Method and apparatus for a J2 interface

摘要

A round robin interface multiplexing up to 4 lines of approximately T1 capacity onto a single J2 circuit. The interface may be built on a card that is utilized on existing telecommunications equipment boxes to allow the existing equipment to be used in conjunction with J2 lines in Japan, or on Japan infrastructure lines purchased and used outside of Japan. The interface also de-multiplexes signals from the J2 line to the separate lines of approximately T1 capacity allowing for reception and transmission of the signals.
