ABSTRACT:
A network is constructed by connecting trunk circuits through a trunk in an exchange in which the trunk circuit connects with a trunk, an extension circuit connects with a terminal, and the trunk circuit is connected to the extension circuit by a path switch controlled by a calling processor and by connecting the terminals to the extension circuit. Control information is transmitted and received by utilizing a channel of a not-in-service trunk up to a time before receiving a response of a remote party to a trunk connection call. The control information is transmitted and received by utilizing a no-signal area in the trunk from a time after receiving the response of the remote party to the trunk connection call to an end-of-service time. The control information on the connection call between two exchanges and the control information on an operational management maintenance of the exchanges are thereby transmitted and received.
