Abstract:
An apparatus for transmitting cells in order to relay through a cell transmission network calls on a line where a communication path is established by call setting control every time communications are needed, comprising:a transmitting side signaling format editing relaying means for editing the signaling format of call setting signals for each call from said line, into a common channel signaling format in which audio information elements belonging to the signaling format are defined and transmitting the call setting signals edited into the common channel format as cell data using a common call setting signal transmission path; a receiving side signaling format editing relaying means for editing the call setting signals edited into said common channel format which are received from said common call setting signal transmission path, into the signaling format corresponding to the signaling format of call setting signals of an called party side line and transferring the signals to the called party side line; and a user signal relaying means for relaying user signals communicated in the call as cell data for each call communicated on said line using a user signal transmission path established corresponding to the call.
