Abstract
Abstract The present invention, in an ATM (Asynchronous Transfer Mode) which houses data in fixed length packets known as cells and transmits them to a receiving end, has as its object to provide a technology which can relay and transmit, within an ATM exchange, overhead section control information and can effectively perform maintenance and management of a communication network. Also, the order wire apparatus of the present invention comprises a network end device between a subscriber terminal and an exchange, this network end device comprising a frame data preparing means for simultaneously mapping communication data transmitted from a subscriber terminal into the payload section of frame data and mapping control information input by a maintenance worker into the overhead section of the frame data. And, the exchange comprises data separating means for separating the frame data transmitted from the network end device into the payload section and overhead section, a cell producing means for forming the payload section and overhead section into individual cells, and a multiplexing means for multiplexing these cells and transmitting them to the receiving end exchange.
