This read-only value reports the operational status of this connection endpoint, reflecting states like operFail, when unrouted, receiving AIS/RDI, or a CC failure occurs, or adminDown, when administratively disabled. An admin uses this as the primary at-a-glance health indicator for an ATM connection, quickly distinguishing an administratively disabled circuit from one that has actually failed due to a routing or continuity problem. For example, if this object reports operFail while continuity check is enabled on the endpoint, the admin would suspect a CC failure or unrouted path as the specific cause rather than an admin-initiated shutdown.
