        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."
