access Switch Vdsl VTU-R Current Status

1.3.6.1.4.1.890.1.5.12.1.1.1.3.1.9

Indicates mandatory state of the VTU-R line. This is a bit-map of possible conditions. The various bit positions are: 0 noDefect There no defects on the line 1 lossOfFraming VTU-R failure due to not receiving valid frame. 2 lossOfSignal VTU-R failure due to not receiving signal. 3 lossOfPower VTU-R failure due to loss of power. Note: the Agent may still function. 4 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. This is intended to supplement ifOperStatus.
