          The key changes made to this MIB module

          since its publication in RFC 2496 are as follows:

      (1) The dsx3FracIfIndex SYNTAX matches the description range.

      (2) Reference was added to Circuit Identifier object.

      (3) Usage of ifStackTable section was updated.

      (4) Align the DESCRIPTION clauses of few statistic objects with

          thenear end definition, the far end definition and with

          RFC 3593.

      (5) Add new value, dsx3M13, to dsx3LineType."

     DESCRIPTION

          "The RFC 2496 version of this MIB module.

          The key changes made to this MIB module

          since its publication in RFC 1407 are as follows:

         (1)  The Fractional Table has been deprecated.

         (2)  This document uses SMIv2.

         (3)  Values are given for ifTable and ifXTable.

         (4)  Example usage of ifStackTable is included.

         (5)  dsx3IfIndex has been deprecated.

         (6)  The definition of valid intervals has been clarified

              for the case where the agent proxied for other devices.

              In particular, the treatment of missing intervals has

              been clarified.

        (7)  An inward loopback has been added.

        (8)  Additional lineStatus bits have been added for Near End

             in Unavailable Signal State, Carrier Equipment Out of

             Service.

        (9)  A read-write line Length object has been added.

        (10) Added a lineStatus last change, trap and enabler.

        (11) Textual Conventions for statistics objects have

             been used.

        (12) A new object, dsx3LoopbackStatus, has been introduced to

             reflect the loopbacks established on a DS3/E3 interface

             and the source to the requests.  dsx3LoopbackConfig

             continues to be the desired loopback state while

             dsx3LoopbackStatus reflects the actual state.

        (13) A dual loopback has been added to allow the setting of

             an inward loopback and a line loopback at the same time.

        (14) An object has been added to indicated whether or not

             this is a channelized DS3/E3.

        (15) A new object has been added to indicate which DS1 is to

             set for remote loopback."
