    摘要： A fault notifying system notifies a fault in an asynchronous transfer mode (ATM) network to at least one data terminating equipment (DTE). The fault notifying system includes a network interface coupled to the ATM network for outputting an alarm indication signal (AIS) when a fault is generated in the ATM network. An ATM crossconnect part generates an AIS cell having a predetermined signal format in response to the AIS. An adaptation layer processing part forms ATM cells, disassembles ATM cells and outputs a data circuit-terminating equipment not ready (DNR) in response to the AIS cell. A terminal interface coupled to the DTE notifies the fault in the ATM network to the DTE in response to the DNR. The AIS cell has a cell format identical to an ATM cell format but has predetermined information in a specific part of the ATM cell format to distinguish the AIS cell from the ATM cell.

    摘要： In an ATM cell assembling and disassembling method for a communications network having first and second communications nodes, HDLC data is transferred from a first terminal to the first communications node via a first transmission line, the HDLC data conforming to an HDLC format. It starts to assemble, in the first communications node, at least one cell from the HDLC data when data which is contained in the HDLC data and equal to one cell has been received. Then the above at least one cell of ATM data is transferred from the first communications node to the second communications node. Disassembly is started, in the second communications node, of the above at least one cell of ATM data to thereby generate original HDLC data when a fluctuation compensation time has elapsed after a first cell of ATM data among the above-mentioned at least one cell of ATM data is received by the second communications node. The fluctuation compensation time is based on a maximum fluctuation time of a route connecting the first and second communications nodes to each other as well as a bit rate of the first transmission line. Finally, the original HDLC data is transferred to a second terminal from the second communications node via a second transmission line.

    摘要： In a VPI and VCI assignment system in an ATM system having a plurality of nodes and terminals, each of the nodes including a conversion unit which generates ATM cells from data sent from one of the terminals, and a node management unit which manages a corresponding one of the nodes, a management unit assigns VPIs and VCIs to calls and manages information concerning VPIs and VCIs currently assigned to the calls and idle VPIs and VCIs. An assignment requesting unit, which is provided in each of the nodes and connected to the management unit, requests the management unit to assign a VPI and a VCI to a call received from one of the terminals. An assignment cancelling unit, which is provided in each of the nodes and connected to the management unit, requests the management unit to cancel the VPI and VCI assigned to the call in response to an end of a communication related to the call.
