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.
LINE
AIS
Displays the alarm indication signal.
This signal is sent by the section terminating equipment (STE) to alert the
downstream line terminating equipment (LTE) that a LOS or LOF defect has been
detected on the incoming interface section.
Path alarm indication signal is sent by the LTE to alert the downstream path
terminating equipment (PTE) that it has detected a defect on its incoming line
signal.
RDI Displays remote defect indication.
This indication is reported by the downstream LTE when it detects LOF, LOS, or
AIS conditions.
BIP(B2) Displays the bit interleaved parity error for the B2 byte.
For B2, the report is calculated by comparing the BIP-8/24 code with the BIP-8
code extracted from the B2 byte of the following frame.Differences indicate
line-level errors.
PATH
AIS
Displays the alarm indication signal.
This signal is sent by the section terminating equipment (STE) to alert the
downstream line terminating equipment (LTE) that a LOS or LOF defect has been
detected on the incoming SONET section.
Path alarm indication signal is sent by the LTE to alert the downstream path
terminating equipment (PTE) that it has detected a defect on its incoming line
signal.
RDI Displays remote defect indication.
This indication is reported by the downstream LTE when it detects LOF, LOS, or
AIS conditions.
BIP(B3) Displays the bit interleaved parity error for the B3 byte.
For B3, the bit interleaved parity error report is calculated by comparing the BIP-8
code with the BIP-8 code extracted from the B3 byte of the following frame.
Differences indicate path-level errors.
Active Defects: Lists the current interface defects.
Active Alarms List the current interface alarms as enforced the interface Alarm Hierarchy.
Alarm reporting enabled
for: List the alarms enabled. Enabled alarms generate trap reports.
