 "This MIB module defines a collection of objects for managing
  HDSL2/SHDSL lines.  An agent may reside at either end of the
  line, however the MIB is designed to require no management
  communication between the modems beyond that inherent in the
  low-level EOC line protocol as defined in ANSI T1E1.4/2000-006
  (for HDSL2 lines), or in ITU G.991.2 (for SHDSL lines)."
REVISION "200205090000Z" -- May 9, 2002
DESCRIPTION "Initial version, published as RFC 3276."

::= { transmission 48 }

 "A gauge associated with interface performance measurements in
  a current 1-day (24 hour) measurement interval.

  The value of this gauge starts at zero at the beginning of an
  interval and is increased when associated events occur, until
  the end of the 1-day interval.  At that time the value of the
  gauge is stored in the previous 1-day history interval, as
  defined in a companion object of type

  Hdsl2Shdsl1DayIntevalCount, and the current interval gauge
  is restarted at zero.

  In the case where the agent has no valid data available for
  this interval the corresponding object instance is not
  available and upon a retrieval request a corresponding error
  message shall be returned to indicate that this instance does
  not exist.  Please note that zero is a valid value."

 "A counter associated with interface performance measurements
  during the most previous 1-day (24 hour) measurement interval.
  The value of this gauge is equal to the value of the current
  day gauge, as defined in a companion object of type
  Hdsl2ShdslPerfCurrDayCount, at the end of its most recent
  interval.

  In the case where the agent has no valid data available for
  this interval the corresponding object instance is not
  available and upon a retrieval request a corresponding error
  message shall be returned to indicate that this instance does
  not exist."

 "The number of seconds that have elapsed since the beginning of
  the current measurement period.  If, for some reason, such as
  an adjustment in the system's time-of-day clock or the addition
  of a leap second, the current interval exceeds the maximum
  value, the agent will return the maximum value.

  For 15 minute intervals, the range is limited to (0..899).
  For 24 hour intervals, the range is limited to (0..86399)."

 "This convention defines a range of values that may be set in
  a fault threshold alarm control.  As the number of seconds in
  a 15-minute interval numbers at most 900, objects of this type
  may have a range of 0...900, where the value of 0 disables the
  alarm."

 "This is the unique identification for all units in a
  HDSL2/SHDSL Span.  It is based on the EOC unit addressing
  scheme with reference to the xtuC."

 configuration profiles are only applicable to SHDSL lines.

 "Contains the actual line rate in this HDSL2/SHDSL span.  This
 should equal ifSpeed."

 "Contains the current Power Spectral Density (PSD) regional
  setting of the HDSL2/SHDSL span."

 "This table supports retrieval of unit inventory information
  available via the EOC from units in a HDSL2/SHDSL line.

  Entries in this table are dynamically created during the
  line discovery process.  The life cycle for these entries
  is as follows:

     - xtu discovers a device, either a far-end xtu or an xru
     - an inventory table entry is created for the device
     - the line goes down for whatever reason
     - inventory table entries for unreachable devices are
       destroyed.
