The MIB module defining objects for the management of a pair
of VDSL transceivers at each end of the VDSL line. Each such
line has an entry in an ifTable which may include multiple
transceiver lines. An agent may reside at either end of the
VDSL line. However, the MIB is designed to require no
management communication between them beyond that inherent in
the low-level VDSL line protocol. The agent may monitor and
control this protocol for its needs.
VDSL lines may support optional Fast or Interleaved channels.
If these are supported, additional entries corresponding to the
supported channels must be created in the ifTable. Thus a VDSL
line that supports both channels will have three entries in the
ifTable, one for each physical, fast, and interleaved, whose
ifType values are equal to vdsl(97), fast(125), and
interleaved(124), respectively. The ifStackTable is used to
represent the relationship between the entries.
Naming Conventions:
Vtuc -- (VTUC) transceiver at near (Central) end of line
Vtur -- (VTUR) transceiver at Remote end of line
Vtu -- One of either Vtuc or Vtur
Curr -- Current
Prev -- Previous
Atn -- Attenuation
ES -- Errored Second.
SES -- Severely Errored Second
UAS -- Unavailable Second
LCS -- Line Code Specific
Lof -- Loss of Frame
Lol -- Loss of Link
Los -- Loss of Signal
Lpr -- Loss of Power
xxxs -- Sum of Seconds in which xxx has occured
(e.g., xxx = Lof, Los, Lpr, Lol)
Max -- Maximum
Mgn -- Margin
Min -- Minimum
Psd -- Power Spectral Density
Snr -- Signal to Noise Ratio
Tx -- Transmit
Blks -- Blocks

Loss of Framing 15-minute interval threshold
(vdslLineAlarmConfThresh15MinLofs) reached.
vdslUpMaxSnrMgnNotification
.1.3.6.1.2.1.10.97.1.0.10
The upstream Signal to Noise Margin exceeded
vdslLineConfUpMaxSnrMgn. The object vdslPhysCurrSnrMgn
will contain the Signal to Noise margin as measured
by the VTU-C.
vdslUpMinSnrMgnNotification
.1.3.6.1.2.1.10.97.1.0.11
The upstream Signal to Noise Margin fell below
vdslLineConfUpMinSnrMgn. The object vdslPhysCurrSnrMgn
will contain the Signal to Noise margin as measured
by the VTU-C.
vdslInitFailureNotification
.1.3.6.1.2.1.10.97.1.0.12
Vtu initialization failed. See vdslPhysCurrStatus for
potential reasons.
vdslPerfLossThreshNotification
.1.3.6.1.2.1.10.97.1.0.2
Loss of Signal 15-minute interval threshold
(vdslLineAlarmConfThresh15MinLoss) reached.
vdslPerfLprsThreshNotification
.1.3.6.1.2.1.10.97.1.0.3
Loss of Power 15-minute interval threshold
(vdslLineAlarmConfThresh15MinLprs) reached.
vdslPerfLolsThreshNotification
.1.3.6.1.2.1.10.97.1.0.4
Loss of Link 15-minute interval threshold
(vdslLineAlarmConfThresh15MinLols) reached.
The downstream Signal to Noise Margin exceeded
vdslLineConfDownMaxSnrMgn. The object
vdslPhysCurrSnrMgn will contain the Signal to Noise
margin as measured by the VTU-R.
vdslDownMinSnrMgnNotification
.1.3.6.1.2.1.10.97.1.0.9
The downstream Signal to Noise Margin fell below
vdslLineConfDownMinSnrMgn. The object vdslPhysCurrSnrMgn
will contain the Signal to Noise margin as measured by
the VTU-R.
