摘要: This disclosure describes techniques for detecting link loss in a physical layer receiver of communication system. The system includes slicer coupled to receive, at input, signal from channel equalizer and map the coding sublayer (PCS) level output processor least one input or output. is configured analyze window consecutive samples over time window; increment counter as function output; compare threshold; generate indicating response determining that corresponds threshold independently timer.
