What is ifOtnMonTcmBackwardDefectIndication?

Indicates whether a receive-side Backward Defect Indication (BDI) alarm is currently active at this TCM layer, per G.709/G.798, meaning the far end of this tandem connection has reported a defect back. An admin treats an active BDI here as evidence of a problem at the remote end of this specific tandem-connection segment.
