An interface receiver coupled among a plurality network elements of at least one network is provided, comprising at least one random access memory (RAM) and at least one comparator. Time slot network (TS net) data frames comprising switching event information are received from each of a number of channels of a backplane network. Compare operations are performed at prespecified intervals among at least one data frame stored in the RAM and at least one subsequently received data frame. Interrupt signals are generated in response to data changes determined by the compare operations.

Interface receive for communications among network elements

A method for routing network switching information includes generating at one Time Slot Network (TS Net) data firame from at least one data frame of a first type. The TS Net data frame comprises switching event information. The TS Net data frame is transferred and stored among a number of network elements using a backplane network. Compare operations are performed among prespecified data frames of the TS Net data frame, and at least one interrupt signal is generated in response to detected changes resulting from the compare operations. Information routing is controlled in at least one network and the associated network elements in response to the interrupt signals.

Method for routing network switching information

An interface for communications among network elements of at least one network is provided, comprising at least one transmitter, at least one receiver, at least one processor, and at least one backplane coupled among the network elements. Data frames of a second type, or Time Slot Network (TS Net) data frames, are generated and transferred over the backplane in response to receipt data frames of a first type from the network. The TS Net data frames comprise switching event information. Compare operations are performed among prespecified TS Net data frames at prespecified intervals, and at least one interrupt signal is generated in response to data changes determined by the compare operations. Information routing is controlled over the network by a processor in response to the interrupt signal.
