What is isdnL2OperStatus?

This read-only OID reports the Layer 2 operational status, including the special 'not-initiated' state when the connection setup has not yet begun. Technicians use this to troubleshoot stuck calls; if it remains 'not-initiated,' the protocol stack failed to start. An 'established' status confirms the Layer 2 link is ready for call signaling.
