METHOD AND DEVICE FOR J2 INTERFACE

摘要

PROBLEM TO BE SOLVED: To provide an interface between a J2 line and multi services and slow access type to be transported via T1 or other lines. SOLUTION: The interface can be constituted in connection with J2 line in Japan or on a card to be used for an existent communication equipment box for enabling using of the existent equipment through a Japanese infrastructure line purchased outside of Japan in Japan and used. This interface inversely multiplexes a signal from the J2 line to another line of a capacity nearly equal to T1 for processing the transmission and reception of a signal.
