Abstract

PURPOSE:To decrease the number of network terminals by providing a trunk circuit for generating a ring-back tone to one of the input side terminal or the output side terminal of a channel network, and providing a call signal to the other. CONSTITUTION:When connection is requested to a subscriber SUBA through the incoming trunk ICT-A from other station, a ring-back tone and a call signal can be sent out to the ICT-A and the SUBA, respectively, by controlling the NW so that the terminal A stored in the outgoing side of the NW of the trunk SGT, and the terminal B stored in the incoming side of the NW are connected to the SUBA and the ICT-A, respectively, without operating the relay S of the SGT. Also, when it is requested to connected the ICT-A and the NW to a subscriber SUBB stored in the outgoing side of the NW through the incoming trunk ICT-B stored in the opposite side, the relay S of the SGT is operated, and a call signal and a ring-back tone can be sent out to the SUBB and the ICT-B, respectively, by controlling the NW so as to connect the terminal A and the terminal B to the ICT-B and the SUBB, respectively.
