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： A virtual channel converter converts a virtual path identifier and a virtual channel identifier, e.g. in a twenty-eight (28) bit frame, attached to the header part of an incoming ATM cell on an input highway to an ATM switcher to identifiers to be attached to an outgoing ATM cell on an output highway capable of fully supporting all the combinations, two hundred fifty-six (256) for example, of a virtual path identifier and a virtual channel identifier no matter where the virtual path identifier and the virtual channel identifier are located in the twenty-eight (28) bit frame. The virtual channel converter comprises a plurality of identifier comparator units and a controller. Each of the identifier comparator units has an input identifier memory for storing an identifier attached to an ATM cell and a comparator for comparing the identifiers of an incoming ATM cell with the identifiers stored in the input identifier memory. The controller instructs respective input identifier memories to store all the values of identifiers attached to incoming ATM cells from a user to a switcher on a one-to-one basis.

摘要： In an address decision system in an ATM exchange, a table memory stores data showing relationships between VPI/VCI values and addresses. A latch circuit latches a VPI/VCI value contained in a cell transferred via a cell highway. A comparator circuit compares the VPI/VCI values stored in the table memory with the VPI/VCI value latched by the latch and generates a comparator output signal showing, in a normal operation, one of the addresses at which the VPI/VCI value from the latch circuit coincides with one of the VPI/VCI values in the table memory. An address decision unit encodes the comparator output signal and generates an encoded signal based on the comparator output signal. A decoder unit decodes the encoded signal and generates a decoded signal. A check unit receives the comparator output signal and the encoded signal and generates an error signal when the comparator output signal and the encoded signal do not match each other.

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.

摘要： When broadcast is executed in an ATM mode, a subscriber is assigned a path and a channel as information by a central controller of a switching unit, and the information is added to a cell to be transmitted to the switching unit through a subscriber line. The switching unit comprises the central controller, a tag information adder, and a self-routing switch. The self-routing switch comprises a plurality of input lines and output lines, and unit switches provided for each input line corresponding to each of the output lines. The tag information adder adds routing information for the self-routing switch to a cell to be transmitted to the self-routing switching. The routing information comprises a set of bits corresponding to each output line, and the tag information adder adds to the cell the routing information in which a bit corresponding to an output line for transmitting the cell is set to a predetermined logical value. In executing the broadcast, a plurality of bits corresponding to a plurality of output lines are set to a predetermined logical value. The self-routing switch analyzes the routing information of the cell received by each unit switch, and outputs the cell to the outpost line if the bit corresponding to a unit switch is set to a predetermined logical value. If a plurality of bits of routing information are set to a predetermined value, the cell is outputted from a plurality of output lines, thus enabling the broadcast.
