    摘要: ATM transmission equipment provided between existing exchange or terminals of carrier equipment that, for example, can emulate existing transmission paths, and also implement T point interfaces for an in-home unit. The ATM transmission equipment detects communication anomalies or extracts maintenance/operation information from data strings on STM lines, such as high-speed digital lines or ISDN lines, and replaces only the necessary information resulting from those extractions or detections with alarm signals. The alarm signals are then transmitted together with information channels to the ATM network via a cell assembler/dissembler. The information channels and alarm information that arrive from the ATM network are rearranged into STM line data strings and output to LT units, DSUs, or terminals.

    摘要: A communication system capable of reliably recovering its communication functions on its own when a fault occurs, and which can be used to construct a highly flexible network. This communication system is configured so that a plurality of node devices (12) supporting data generating sources are connected via communication paths (13) that use ATM technology to a plurality of center devices (11), just as if it possessed distributed ATM switch functions. When the communication paths (13) between two (2) node devices (12-2 and 12-3) are cut, the center device (11-2) detects the fault point, and autonomously recovers communication functions by transferring the node device (12-2) originally under its control to the control of the center device (11-1). When this happens, the center device 11-2) cannot communicate via the communication paths (13) due to the fault, and must use a local communication means such as a wide area network (16) to communicate with the center device (11-1).
