This notification is generated when the pwOperStatus object for one or more contiguous entries in the pwTable are about to enter the down(2) or lowerLayerDown(6) state from any other state, except for transition from the notPresent(5) state. For the purpose of deciding when these notifications occur, the lowerLayerDown(6) state and the down(2) state are considered to be equivalent; i.e., there is no notification on transition from lowerLayerDown(6) into down(2), and there is a trap on transition from any other state except down(2) (and notPresent) into lowerLayerDown(6).
The included values of pwOperStatus MUST each be equal to down(2) or lowerLayerDown(6). The two instances of pwOperStatus in this notification indicate the range of indexes that are affected. Note that all the indexes of the two ends of the range can be derived from the instance identifiers of these two objects. For cases where a contiguous range of cross-connects have transitioned into the down(2) and lowerLayerDown(6) states at roughly the same time, the device SHOULD issue a single notification for each range of contiguous indexes in an effort to minimize the emission of a large number of notifications. If a notification has to be issued for just a single cross-connect entry, then the instance identifier (and values) of the two pwOperStatus objects MUST be identical.
