    摘要: A self-routing exchange which includes switch modules connected in multiple stages. A synchronous transfer mode (STM) circuit switch module, which is capable of changing over a connection relationship between incoming highways and outgoing highways, is provided between the multistage-connected switch modules and self-routing switch modules. Asynchronous transfer mode (ATM) switch modules are provided as switch modules in preceding and succeeding stages of the circuit switching module. In dependence upon the number m of self-routing switch modules, a controller sets, by means of software, the connection relationship between the incoming and outgoing highways in each of space switches incorporated within the circuit switching module. As a result, the total mn-number of incoming highways from the self-routing switch modules are connected to respective ones of mn-number of outgoing highways set by the controller. In a case where self-routing switch modules are added on later to expand the system, the controller changes the connection relationship between the incoming and outgoing highways in each space switch within the circuit switching module, using software.

    摘要: In a data access device for writing into or read from a data conversion table on the basis of a clock signal extracted from a cell being transferred over a line, a clock signal generator of the invention generates a second clock signal which differs from the first clock signal extracted from an incoming cell. A write/read control unit writes data into or reads data for maintenance from the data conversion table on the basis of either the first clock signal or the second clock signal when the line is normal. In the event of the occurrence of a failure in the line, on the other hand, the write/read control circuit permits the data conversion table to be written into or read from for maintenance on the basis of the second clock signal.

    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 peripheral device cable, connected to a peripheral device, integrally incorporates a subscriber link that is a physical line for transmitting subscriber information in synchronization with a highway clock and a control link that is a physical line for transmitting control data in synchronization with the highway clock. A control data converter controls interfacing between the control data transferred over the control link synchronously with the highway clock and control data that a control unit transmits/receives asynchronously with the highway clock. The subscriber link is connected to a switch.

    摘要: A service identification adding portion adds service identification information to a cell corresponding to each connection that uses a predetermined communication service (ABR service) and that is input to a switch system. A connection number counting portion counts the number of connections that use the communication service on each output line at predetermined intervals. A band control information generating portion generates band control information corresponding to each output line at predetermined intervals based on the number of connections counted at predetermined intervals. A band control information indicating portion sends band control information at predetermined intervals corresponding to each output line to a transmission side terminal corresponding to a connection that uses the communication service on each output line.

    摘要: Four SR modules are provided in the second stage of a 3-stage MSSR switch. To guarantee the MSSR switch the capacity of 20 Gbps, SR modules are provided in each of the first and third stages of the switch. When the capacity of the MSSR switch is extended from 20 Gbps to 40 Gbps, SR modules are added to both of the first and third stages and connected to the four SR modules in the second stage. To further extend the capacity of the MSSR switch to 60 or 80 Gbps, the SR modules are sequentially added to the first and third stages, and the newly provided SR modules are connected to the four SR modules in the second stage.
