DESCRIPTION
This field displays the VDSL2 template profile applied to this line.
This is the transmission standard this line uses. The possible modes are G.993.2 Annex A
(for countries which follow the North American VDSL2 standard) or G.993.2 Annex B (for
the other countries).
This field displays the failure cause at last line initialization. noFail means the line was
last successfully initialized.
This field displays the last successful transmitted initialization state in the last full
initialization performed on the line. The initialization states are defined in ITU-T G.993.2.
VTUC CH DISCOV1: VTU-C transmitted the O-P-CHANNEL DISCOVERY 1 signal.
VTUR CH DISCOV1: VTU-R transmitted the R-P-CHANNEL DISCOVERY 1 signal.
VTUC CH DISCOV2: VTU-C transmitted the O-P-CHANNEL DISCOVERY 2 signal.
VTUR CH DISCOV2: VTU-R transmitted the R-P-CHANNEL DISCOVERY 2 signal.
VTUC TRAINING1: VTU-C transmitted the O-P-TRAINING 1 signal.
VTUR TRAINING2: VTU-R transmitted the R-P-TRAINING 2 signal.
VTUC_MEDLEY: VTU-C transmitted the O-P-MEDLEY signal.
VTUR_MEDLEY: VTU-R transmitted the R-P-MEDLEY signal.
VTUC TRAINING1 LD: VTU-C transmitted the O-P-TRAINING 3 signal.
VTUR TRAINING1 LD: VTU-R transmitted the R-P-TRAINING 3 signal.
This field displays any existing upstream (Xtuc) or downstream (Xtur) failure that
occurred on this line.
NoDefect: No failure was detected.
LossOfFraming: A loss of frame synchronization was detected.
LossOfSignal: A loss of signal was detected.
LossOfPower: A loss of power was detected.
InitFailure: The most recent initialization failed.
This field displays the maximum downstream/upstream data rate for this line.
This field displays the PSD levels this line uses for downstream/upstream transmission.
This field displays the total amount of downstream/upstream transmission power for this
line, in units of 0.1 dBm.
This field displays the total amount of downstream/upstream receiving power for this line,
in units of 0.1 dBm.
This field displays whether the downstream/upstream transmitter referred virtual noise is
enabled or disabled.
This field displays whether trellis coding is used in the downstream/upstream
transmission.
This field displays the downstream/upstream signal-to-noise (SNR) margin of this line. 0
dB means no SNR margin.
