Indicates mandatory state of the ATUC line, i.e. the state of the line as seen by ATUC. This is a bit-map of possible conditions. The various bit positions are: 1 noDefect There no defects on the line 2 lossOfFraming ATUC failure due to not receiving valid frame. 3 lossOfSignal ATUC failure due to not receiving signal. 4 lossOfPower ATUC failure due to loss of power. Note: the Agent may still function. 5 lossOfSignalQuality Loss of Signal Quality is declared when the Noise Margin falls below the Minimum Noise Margin, or the bit-error-rate exceeds 10^-7. 6 lossOfLink ATUC failure due to inability to link with ATUR. 7 dataInitFailure ATUC failure during initialization due to bit errors corrupting startup exchange data. 8 configInitFailure ATUC failure during initialization due to peer ATU not able to support requested configuration 9 protocolInitFailure ATUC failure during initialization due to incompatible protocol used by the peer ATU. 10 noPeerAtuPresent ATUC failure during initialization due to no activation sequence detected from peer ATU. 11 lossOfCellDelineation ATUC failure due loss of Cell Delineation in interleaved and non-interleaved mode. This is intended to supplement ifOperStatus. Enumerations: - noDefect (1)
- lossOfFraming (2)
- lossOfSignal (3)
- lossOfPower (4)
- lossOfSignalQuality (5)
- lossOfLink (6)
- dataInitFailure (7)
- configInitFailure (8)
- protocolInitFailure (9)
- noPeerAtuPresent (10)
- lossOfCellDelineation (11)
