摘要： A data sending method, where the method includes receiving, by a forwarding device using a first flexible Ethernet (FlexE) group and in multiple timeslots included in a first timeslot set, multiple first encoded data blocks from a physical coding sublayer (PCS), determining, by the forwarding device according to the timeslots included in the first timeslot set and the first FlexE group, a second FlexE group and multiple timeslots included in a second timeslot set, and sending, by the forwarding device, the first encoded data blocks using the second FlexE group and in the timeslots included in the second timeslot set. The forwarding device does not need to process the first encoded data blocks in a conventional layer 2 or layer 3 forwarding mode. Therefore, a processing delay can be reduced, and a transmission delay can be reduced.

摘要： The present invention provides an improvement in circuit switching for a network comprising a switching apparatus including a plurality of transceivers for interfacing directly with a like plurality of nodes. Each of the transceivers has a receive and transmit through port for passing data to and from nodes. Transmitted data includes a connect/disconnect sequence, a first wait sequence, and user data. The switching apparatus further includes circuitry for isolating each transceiver so as to loop back data when not in use and a switching matrix for directly connecting any pair of transceivers. Each of the transceivers includes circuitry for detecting a connect and disconnect sequence and an interface for connection to a serial asynchronous receiver to derive node requests, routing data, priority and other information from the connect sequence detected at the transceiver. Derived switch configuration requests are processed by a node route control state machine, with each node route control state machine integrated in a bus architecture for configuring the matrix switch. A bus arbitration state machine controls the bus architecture servicing bus requests and providing bus grants for the transfer of routing information to switch control logic and a command sequencer. The requesting node may set a priority for a connection request, queue a connection request or alternatively request data from the switch controller micro-controller core.

摘要： A method for implementing switching in the time or space domain, in which the switching is effected on the basis of switching data contained in an address control memory, and a basic switching block is defined on the basis of an incoming frame structure so that the number of its time slots corresponds to the greatest possible number of signals of the lowest level of hierarchy to be switched in the frame. The basic switching block recurs in the same form with respect to switching. In order for the switching to be simplified: (i) the number of the switching instructions to be stored in the address control memory corresponds to the size of the basic switching block, whereby when the basic switching block also contains higher-level signals, the same switching instruction is used in the address control memory at given intervals, depending on how the signals occur in the basic switching block, (ii) the same address control memory is read during the entire frame structure, whereby it gives a switching instruction to all time slots in the frame, and (iii) the switching instructions read from the address control memory are skipped during the time slots which are not cross-connected.

摘要： In a system and method of communication between circuit mode units interconnected by point-to-point circuits in a subnetwork at the core of a communication installation the point-to-point circuits between units are structured and managed identically. A communication circuit is incorporated in each unit of the subnetwork, irrespective of the control unit, auxiliary unit or telephone and/or communication terminal interface controller type. This communication circuit handles the broadcasting over the point-to-point circuits to the other units of data from time-division multiplex circuits connected to it and switching of bytes addressed to it over the circuits.

摘要： When a group communication group call is initiated in a multi-site communication system, the communication processing information for that particular communication group call must be established. The communication processing information is formatted by a central controller which in turn transfers that information to a destination data base of a processing multiplexer switch. The information is then stored in the destination data base such that the particular communication group call may be quickly processed. When the communication unit that initiated the call ceases to transmit and another communication unit begins to transmit, the communication processing information is updated to reflect the change in the transmitting communication unit. This continues to happen until the particular communication group call has ended; once it has ended, the communication processing information is deleted from the destination data base.
