Card Alarms Screen – Model 8365
D-B
Displays alarms for the card and port levels. Columns on this screen represent port
numbers (01–12).
Major Alarms
:
Selftest
– Shown as Pass or Fail.
ATM Bus Failure
– If ALARM appears on this line, there has been a Loss Of Clock (LOC)
because the line card is unable to communicate with the SCM. This could be because the
chassis does not support the ATM bus (the chassis is not an 8620 or 8820 BLC), or the
SCM card has been removed from the chassis.
DSL Port Selftest Fail
– DSL port self-test results. A result code is shown for each port:
P for Pass or F for Fail.
Minor Alarms
:
Config Error
– If ALARM appears on this line, the card has detected a checksum error in
the memory where the configuration is stored.
Loss of Cell Delineation
– If a loss of cell delineation has been detected on the port, an
A (for Alarm) appears in the column for that port.
Loss of Signal
– If a loss of signal has been detected on the port, an A (for Alarm)
appears in the column for that port.
The following alarms are monitored in both the downstream and upstream direction
except for SN Loss of Power (upstream only) and CAC Exceeded (upstream only):
Error Seconds
– The number of Errored Seconds has exceeded the user-defined
threshold.
Severely Errored Seconds
– The number of Severely Errored Seconds has exceeded
the user-defined threshold.
Unavailable Seconds
– The number of Unavailable Seconds has exceeded the
user-defined threshold.
SN Loss of Power
– The endpoint has lost power.
