Patent ID: 7292608

Claim:
A system for transferring synchronous optical network/synchronous digital hierarchy (SONET/SDH) frames between a first and second node comprising: a demultiplexer to map frame markers used to generate framing pulses and frame bytes of a SONET/SDH frame onto a plurality of data channels; an encoder to encode and translate the frame markers and frame bytes on each data channel for transmission; a first de-skewing processor to overwrite the frame markers on the SONET/SDH frame with unique frame markers to aid in de-skewing the plurality of data channels and to maintain the framing pulses; a second de-skewing processor to de-skew the data from the plurality of data channels based on the unique frame markers and to restore the frame markers on the SONET/SDH frames to recover the framing pulses; a decoder to decode and translate the framing markers and frame bytes on each data channel for reception; and a multiplexer to map the plurality of data channels and the recovered framing pulses onto the SONET/SDH frame.
