摘要： A routing method routes cells which are transferred through one of a plurality of paths within an asynchronous transfer mode (ATM) switching system selected by routing information. The routing method includes the steps of adding first routing information to incoming cells at an input stage of the ATM switching system when supplying the cells to the ATM switching system, generating a route switching confirmation cell in response to a route switching instruction and for adding second routing information to incoming cells thereafter so as to supply the route switching confirmation cell and the cells added with the second routing information to the ATM switching system. The second routing information is different from the first routing information and is determined by the route switching instruction, comparing routing information. The method also includes the cells with the second routing information at an output stage of the ATM switching system in response to the route switching instruction, and outputting each cell from the ATM switching system having routing information different from the second routing information as it is. The method also includes temporarily storing each cell from the ATM switching system having routing information identical to the second routing information and reading out and outputting the stored cell after the route switching confirmation cell is output from the ATM switching system.

摘要： A self-routing switching system connected between input highways and output highways, includes conversion modules, doubled SRM networks, output modules, and first and second selectors. Normally, one of the SRM networks is connected between the conversion modules and output modules through the first and second selectors. When a request to switch the active network to the other SRM network is received, the first and second selectors switch connections to the conversion modules and output modules so that the other SRM network is connected between the conversion modules and output modules. Before actually switching the connections, it is determined whether or not all cells have been discharged from the active SRM network.

摘要： A transmission control system in which terminals are connected to an ATM switching network, has a table circuit registering virtual channels presently formed in the ATM switching network in a management table, and a retrieval part for receiving a communication request from one of the terminals and for determining whether or not the management table registers a virtual channel corresponding to the communication request. Data output from one of the terminals is transferred to a different one of the terminals addressed by the communication request through the virtual channel corresponding to the communication request and corresponding two of the terminal adapters, when the retrieval part determines that the management table has the virtual channel corresponding to the communication request. A virtual channel setting part registers the virtual channel corresponding to the communication request in the management tabele, when the retrieval processor determines that the management table does not have the virtual channel corresponding to the communication request. Data output from the one of the terminals is transferred to the different one of the terminals addressed by the communication request through the virtual channel registered in the management table by the virtual channel setting part.

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： 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.
