DESCRIPTION

    "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
