Providing TDM services over a packet-switched fabric. Distributed scheduling is provided by overlaying a synchronized frame structure on the packet switching of the packet-switched fabric. Contention-free scheduling is achieved by prescheduling TDM traffic with the distributed scheduling mechanism. The result is a deterministic timing procedure suitable for switching TDM traffic in a packet-switched fabric.

TDM services using a packet-switched fabric

A system and method of transmitting data cells are disclosed. The system includes a data transmitting and receiving unit including transceiver circuitry, a main backplane interface, and backplane interconnection circuitry. The transceiver circuitry transmits and receive data cells over the data link, the main backplane interface provides physical interconnection to the backplane, and the backplane interconnection circuitry transmits and receives cells. The main backplane interface including at least one cell signal terminal and at least one operations data signal terminal. The operations data signal terminals are separate from the cell signal terminals. The operations data signal terminals and the cell signal terminals are configured to connect to mating connectors on a backplane. Backplane interconnection circuitry couples the transceiver circuitry to the main backplane interface. The interconnection circuitry receives data cells from the transceiver circuitry and transmit them over cell signal terminals, receives data cells from the cell signal terminals and provide them to the transceiver circuitry for transmission over the first data link, and transmit and receive operations data over the operations data signal terminals. The method includes asserting a signal indicating the priority of a cell to be transmitted over the backplane, receiving on a second backplane signal line a signal that the apparatus may begin transmitting the data cell, and transmitting bits of the data cell on a third backplane signal line after receiving the signal that the apparatus may begin transmitting the data cell.
