Clear Alarms – EOC

NOTE: EOC Interface – This procedure describes Access Navigator alarm messages sent to the local switch over the GR-303 Embedded Operations Channel (EOC). Because some EOC messages are reported only to the local switch, it is recommended that this procedure be followed to identify EOC alarms. If Command Line Interface (CLI) commands are needed to clear the alarm, the operator should go to Clear Alarms – FDL on page 14-3.

NOTE: Alarms – The EOC has four alarm levels:

CRITICAL alarms affect service to 128 or more subscribers.

(No critical alarms are currently defined. The Access Navigator

does not report manually set alarms (used for maintenance testing) over the EOC.) MAJOR alarms affect service to 24 or more subscribers.

MINOR alarms are non-service affecting, but reduce reliability. WARNING alarms are non-service affecting, but reduce reliability.

(Warnings are reported only to the local switch, not to the CLI.)
