Patent ID: 7505456

Claim:
A system for passing TDM traffic through a packet switch, comprising a packet switch having a plurality of data ports and configured to route FSDU (fixed sized data unit) packets between the plurality of data ports; a TDM encapsulation circuit coupled to a data flow of TDM data and having a circuit demultiplexer for processing an incoming data flow of TDM data to buffer data associated with different TDM circuits into different buffer locations, and for accessing a connection table having information representative of the plurality of data ports being supported by the packet switch including two or more data ports associated with a respective route through which an FSDU associated with a respective circuit is routed by the packet switch, a timer for monitoring a frame boundary, and a FSDU generator for generating an FSDU and filling the generated FSDU with data associated with a respective one of the TDM circuits and for generating header information representative of information for allowing the packet switch to route the generated FSDU to a respective one of said plurality of data ports, said respective port being associated with the respective one of the TDM circuits.
