    摘要： An ATM (asynchronous transfer mode) exchange has a buffer for system #0 and a buffer for system #1 providing P-MEM's for storing data including an A bit and for a VCI/VPI currently in use is set to "1'. Upon detecting a switchover between the systems, every B bit is reset to "0". When the exchange while changing from a master to a slave receives a cell having a slave indication and while changing from a slave to a master it receives a cell having a master indication, respective systems rewrite B bits for VCI/VPI's of respective cells to "1". In the meantime, each of the P-MEM's calculates exclusive "OR" operations between the A bit and the B bit for every VCI/VPI, and further obtains a disjunction among all the exclusive "OR" operations thus obtained. Then, when both P-MEM's obtain "0" for their respective disjunctions, cells are read out from one of the buffers in the system changing from a slave to a master. This enables the ATM exchange having a switch duplexed by mutually asynchronous active and backup systems to switchover the systems without causing a cell to be duplicated or lost.

    摘要： A switch interface unit, a monitor unit, and a control system interface unit are connected as external units to a highway to which a subscriber information processing unit is also connected so that a monitoring process, that is, a special study process, can be simplified and a cost charged for the subscriber information processing unit can be prevented from increasing greatly. Furthermore, in an accounting process, accounting parameters are accumulated in an accounting information accumulating unit for variations on compressed source addresses, not on source addresses. As a result, the accounting information accumulating unit, etc. can be realized with normal circuit elements only.

    摘要： A test cell generating section periodically generates a pass determining test cell at preset timing, multiplexes them with user cells from a user line interface, and transmits the result of multiplexing to an ATM exchange. When no user cell is supplied from the user line interface, the test cell generating section transmits only the pass determining test cell to the ATM exchange. A cell determining section determines whether a cell supplied from the ATM exchange is a user cell or test cell, identifies/determines the pass based on information of the test cell and outputs only the user cell to the user line side when the supplied cell is the test cell.

    摘要： The object of the present invention is accomodating local connectionless information (data that is immediately transferred without establishing a path to a receive side), such as LAN data in a local area network, by an asynchronous transfer mode (ATM) network using a connection-oriented communication system (which makes data transfers after verifying that a path to the receive side has been established), thereby performing efficient, fast routing of connectionless information. A connectionless communication system of the present invention is equipped with connectionless information cell assembly/deassembly means for bi-directional conversion between variable-length connectionless information and fixed-length connectionless cells, routing control means for analyzing a destination address of information in connectionless cells and controlling the routing of the connectionless cells; and an ATM network for connecting the connectionless information cell assembly/deassembly means and the routing control means by a permanent virtual channel serving as a fixed path and connecting the routing control means together by a virtual channel serving as a semi-fixed path, whereby connectionless information is segmented into connectionless cells and the connectionless information is exchanged within the ATM network in connectionless cell units.

    摘要： An error check of a signaling data divided into divided signaling data transferred asynchronously in a unit of cells is performed in a signaling data receiving and processing unit in a digital exchange. The exchange is connected with terminal equipment arranged in a narrow band ISDN environment in a broadband ISDN system. The error check is performed by calculating an error check code for every byte of the signaling data as it is received, accumulating the result until the cyclic redundancy code, encountered in the last byte of the signaling data, is accumulated and performing matching between the accumulated result and a constant value produced based on the CRC system. The checking is performed while the signaling data is stored in a data memory in the signaling data receiving and processing unit. The data memory provided in the signaling data receiving and processing unit has memory regions capable of storing the signaling data sent from the terminal which is allocated as needed by a central controller of the digital exchange.

    摘要： A first form of an ATM channel testing apparatus tests an ATM channel by having a test cell detector in each switch to detect whether or not the switch appropriately switches a test cell generated by a test cell generating trunk. A second form of an ATM channel testing apparatus easily tests an ATM channel by having test cell generators provided for the respective input highways sequentially generating test cells including test cell identifying information and input highway identifying information, and having test cell checkers provided respectively for the output highways simply tally the test cells by the respective input highways. A third form of an ATM channel testing apparatus tests an ATM channel with less pieces of hardware by having turnaround parts in respective ordinary trunks sequentially turn around a test cell generated by a test cell generating trunk to be finally returned to the test cell generating trunk. A fourth form of an ATM channel testing apparatus tests an ATM channel by having a test cell checker provided for each of output highways to examine whether or not the test data carried in respective octets of the payloads in extracted test cells are of consecutive values.
