   DESCRIPTION

       ADSL modems at each end of the ADSL line.  Each such line has

RFC 2662                     ADSL Line MIB                   August 1999


       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:

                 Atur -- (ATUR) modem at Remote end of line
