摘要： A synchronization circuit for ATM cells transferred in an ATM communication system, wherein the synchronization circuit receives and holds in a bit serial manner the input bit trains constituting the received ATM cells by a shift register unit, performs a CRC operation in a bit serial manner on the held input bit trains by a continuous CRC arithmetic unit in accordance with a simplified CRC operation process different from the usual CRC operation process, and performs the necessary synchronization control upon receiving the CRC arithmetic operation result at a synchronization control unit, thereby enabling CRC arithmetic operations to be performed continuously and by simple hardware on the headers in the ATM cells.

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 a header driven type packet switching system, all incoming and outgoing lines required for the system are divided into groups to constitute a two stage structure of incoming and outgoing modules, which are prepared for the respective incoming and outgoing line groups. In each incoming module, outgoing module and outgoing line, information is given to packets, and the data packets are successively transferred from the outgoing modules to the corresponding outgoing lines. Thus, the system can flexibly cope with an increase of the incoming lines and the number of calls.
