The definition of each alarm severity comes from Bellcore TR-NWT-000474. An alarm can be:
•Critical, indicating complete, non-recoverable failure, loss of data, and do on. The failed entity m ust
be restored. A power failure or a line being disconnected is an example.
•Major, indicating service-affecting e rrors. This event indicates that a m aj or s e rv ic e i s d ama ged or
lost, but the existing traffic is no t a ffected.
•Minor, indicating non-service affecting errors or errors on a remote node. Corrective action is
appropriate to prevent a serious fault from developing. An example is a fan failure, where no
subscribers are immediat ely affected, but calamity cou ld result if the situatio n persists. Note that an
accumulation of lower-level alarms does eq ua l a h igher-level alarm.
