Abstract

PURPOSE:To omit a multi-frequency signal receiver by providing a local specific incoming route only for the transmission of positive-direction signals. CONSTITUTION:The communication between terminating station A and originating station B through transmission path 9 is performed in the positive-direction (B to A) and reverse-direction (A to B), namely, two-way MFC signal system, however, signal receiving only in the positive direction (the direction from local specific route 10 to incoming register 2 of the terminating station) is performed in respect to incoming connection unit 10 provided with the local specific incoming route. Then, in case of the reverse direction (the direction from incoming register 2 of the terminating station to local specific route 10), signals are ignored because no receiver is provided in incoming connection unit 10 provided with the local specific incoming route. However, information such as network block is sent to the originating station in a busy time.
