Alarm and Error Reporting

Alarm and Error Reporting
During normal operations, software or firmware may detect error conditions
relevant to specific MOs. The system attempts to either fix or circumvent these
problems automatically. An alarm is raised if a hardware component incurs too
many errors.
Errors are detected in two ways:
For "in-line" errors, firmware on the component detects the occurrence of
an error during ongoing operations.
For other types of errors, a "periodic test" or a "scheduled test" started by
the software detects the error. The technician can run these tests on
demand by using the maintenance commands described in
''Maintenance
''Maintenance
When an error is detected, the maintenance software puts the error in the Error
Log and increments the error counter for that error. When an error counter is
"active" (greater than zero), there is a maintenance record for the MO.
Alarms are classified depending on their effect on system operation:
— MAJOR alarms identify failures that cause a critical degradation of service.
These alarms require immediate attention.
— MINOR alarms identify failures that cause some service degradation but
that do not render a crucial portion of the system inoperable. MINOR
alarms require attention. Typically, a MINOR alarm affects only a few trunks
or stations or a single feature.
— WARNING alarms identify failures that cause no significant degradation of
service or equipment failures external to the switch. These failures are not
reported to INADS or to the attendant console.
— ON-BOARD problems originate in the circuitry on the alarmed circuit pack.
— OFF-BOARD problems originate in a process or component that is external
to the circuit pack.
