Line Description
interface is... Displays the interface type and the slot and port number information.
SECTION
LOF
Displays the section loss of frame (LOF) error.
This error is detected when a severely error framing (SEF) defect on the incoming interface
signal persist for 3 milliseconds
LOS Displays the loss of signal (LOS) error.
This error is detected when an all-zeros pattern on the incoming interface signal lasts 19 plus
or minus 3 microseconds or longer. This defect might also be reported if the received signal
level drops below the specified threshold.
BIP(B1) Displays the bit interleaved parity error for the B1 byte.
For B1, the report is calculated by comparing the BIP-8 code with the BIP-8 code extracted
from the B1 byte of the following frame. Differences indicate section-level errors.
