Description
Section BIP-8 - bit-interleaved parity code 8 - even parity
for error monitoring
Line BIP-8 - line error monitoring
Path BIP-8 - path error monitoring
Loss of signal. The loss of signal defect is declared when
no transitions are detected on the incoming signal
(before descrambling). The LOS defect is detected upon
observing 2.3 to 100 microseconds of no transitions.
The defect is cleared after a 125 microsecond interval
(one frame) during which no LOS defect is detected.
Loss of frame. A loss of frame defect is declared when
an OOF/SEF defect persists for a period of 3
milliseconds. The LOF defect is terminated when the
incoming signal remains continuously in-frame for a
period of 1 ms to 3 ms.
