What is itrLinkFunctionalStatus?

Reports the physical-layer health of this WAN link: ok(1) fully functional, fail(2) a general fault, noRxClk(3) specifically missing a receive clock signal from the far end or modem, or disable(4) administratively shut down; noRxClk is a useful specific clue pointing an admin toward a modem or carrier clocking problem rather than a generic cable fault.
