Description: The line operational status is the composition (ie, logical OR'ing) of definitions from GR-303-CORE. Some of them are service affecting, some of them don't affect the ability of service. Valid states are: * up, line is operational * fault (FLT), a fault condition * manualOos (MTCE), object is manually taken OOS for maintenance purpose * removedFromServiceBySwitch (SWTCH), entity removed from service by switch * UnEquipped - default state when new CRV entry is added * notConnected, line is not connected

What is igCrvOperStatus?

A bitmask reporting this CRV line's operational condition as the logical OR of GR-303 status bits: up, fault, manualOos, removedFromServiceBySwitch, unEquipped (the default for a newly-added CRV), and notConnected. Admins decode this bitmask to distinguish a genuine line fault from a line that's simply been manually taken out of service for maintenance.
