ABSTRACT:
A maintenance and supervising system and method for a multiplex communication system having mutually connected multiple pieces of multiplex communication equipment. A call controller executes call control by common channel signaling. A multiplexer multiplexes multiple communication data, and a fixed connection allocation device allocates multiplexed data within a multiplex circuit fixedly. A dynamic connection allocation device allocates multiplexed data within the multiplex circuit dynamically, and a piece of connection form switching equipment is provided. A piece of terminal equipment for maintenance and supervising is connected to one of the pieces of multiplex communication equipment. A call connection message is transmitted via common channel signaling, and the piece of maintenance and supervising equipment and the piece of multiplex communication equipment to be maintained and supervised are connected by securing a dynamic connection band in a multiplex circuit at the time of maintenance and supervising. The dynamic connection band is used for normal communication when not in use for maintenance and supervising.
