What is isdnLapdOperStatus?
Read-only Layer 1/Layer 2 status of this D channel: inactive means both layers are down, l1Active means the physical layer is up but the LAPD datalink isn't established, and l2Active means the datalink is fully up - useful for isolating whether an ISDN line problem is physical or protocol-level.
