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.

摘要： On receiving voice data from a subscriber accommodated in a broadband network, a terminal adaptor separately puts the voice data in cells in 8-bit units every 125 .mu.s separately, and transmits the cells by a remote switching unit in the broadband network to subscriber terminal equipment. The subscriber terminal equipment accommodates and processes each item of 8-bit data in 24 channels in the PCM format, puts in cells the PCM-formatted data in 24 channels, and sends the cells sequentially to a broadband network transmission line through the remote switching unit. On receiving the above described data in cells, an adaptor provided between the broadband network and an existing telephone network converts the data to the PCM transmission format, and sends them to the existing telephone network after adding a signaling bit to them.

摘要： An in-service activator for a broadband exchanger has a dual system structure, in which a first system and a second system form a dual pair. The first system and the second system in the dual pair each has at least one [1] channel converter and a switcher. A channel converter stores channel setting information for use in routing a cell inputted from a line, and outputs the cell inputted from the line by attaching the channel setting information to the cell. The switcher switches a cell outputted from a channel converter. The interfacer stores, in a channel converter of a to-be-activated standby system in the dual pair, the channel setting information read from the corresponding channel converter of an act system in the duplex pair.

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： An index value output circuit outputs an index value in response to a VCI added to the first signaling cell outputted from a terminal unit. A switching data output circuit outputs switching data for determining a path for signaling cells, based on the index value. Hence, by revising the index value according to a congestion state of an ATM switch, the above path is dynamically changed. The same index value is inserted in the second and subsequent signaling cells outputted from the terminal unit. Because switching data are based on the same index value, all signaling cells from the same terminal units are fed to the same signaling terminator.
