Indicates current state of the Vtur line. This is a bit-map of possible conditions. Due to the isolation of the Vtur when line problems occur, many state conditions like loss of power, loss of quality signal, and initialization errors, can not be determined. While trouble shooting Vtur, also use object, adGenVdsl2VtucCurrStatus. The various bit positions are: Bit 00 : There no defects on the line Bit 01 : Vtur failure due to not receiving valid frame. Bit 02 : Vtur failure due to not receiving signal. Bit 03 : Vtur failure due to loss of power. Note: the Agent may still function. Bit 04 : 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.
