What is lapbdDlcLinkLevelState?
Reports the detailed link-establishment state of this data-link connection, from disconnectedDisabled(1, no connection requested yet) through connectingLinkLevel(2) and dataTransfer(3, normal operation) to disconnectingLinkLevel(4) and error states like frameRejection(8). An admin troubleshooting a stalled link would check this to see exactly where negotiation is stuck, e.g. connectingAwaitingTei(5) means it's still waiting on ISDN TEI assignment.
