   DESCRIPTION
       "The MIB module defining objects for the management of a pair of
       ADSL modems at each end of the ADSL line.  Each such line has

Top      Up      ToC       Page 21 
       an entry in an ifTable which may include multiple modem lines.
       An agent may reside at either end of the ADSL line however the
       MIB is designed to require no management communication between
       them beyond that inherent in the low-level ADSL line protocol.
       The agent may monitor and control this protocol for its needs.

       ADSL 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 an ADSL
       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 adsl(94), fast(125), and
       interleaved(124), respectively. The ifStackTable is used to
       represent the relationship between the entries.

       Naming Conventions:
                 Atuc -- (ATUC) modem at near (Central) end of line
                 Atur -- (ATUR) modem at Remote end of line

                 Prev -- Previous
                 Atn -- Attenuation
                 ES  -- Errored Second.
                 LCS -- Line Code Specific
                 Lof -- Loss of Frame
                 Lol -- Loss of Link
                 Los -- Loss of Signal
                 Lpr -- Loss of Power
                 xxxs-- interval of Seconds in which xxx occurs
                         (e.g., xxx=Lof, Los, Lpr)
                 Max -- Maximum
                 Mgn -- Margin
