Power optimization mechanisms for framers by selectively deactivating frame alignment process

A receiver in a telecommunication system, said receiver comprising:

• an input interface configured to receive a data stream comprising a plurality of frames, wherein each frame comprises a known frame alignment word;
• and
• a framer coupled to said input interface and configured to:
• identify a location of said known frame alignment word in said data stream;
• generate a first indication of frame alignment success based on identification of said location;
• enter a power reduction state based on said first indication;
• and
• exit said power reduction state responsive to a second indication that an error in a processed data stream subsequent to said frame alignment success exceeds a threshold, wherein said processed data stream is generated based on said data stream.

A receiver in a telecommunication system, said receiver comprising:

• a plurality of framers coupled to a plurality of physical lanes, wherein a respective framer is configured to:
• perform a frame alignment process on a data stream from a corresponding physical lane;
• and enter into a power reduction state responsive to a frame alignment success event;
• and
• a forward error correction (FEC) decoder coupled to said plurality of framers and configured to:
• detect an error in a reconstructed data stream subsequent to said frame alignment success event, said reconstructed data stream generated from data streams of said plurality of physical lanes;
• and
• generate an indication responsive to a determination that said error exceeds a prescribed limit,
• wherein said respective framer is further configured to exit said power reduction state and resume said frame alignment process on said data stream responsive to said indication.
