+          The key changes made to this MIB module
+          since its publication in RFC 1407 </rfcs/rfc1407.html> 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."

+            "This table is deprecated in favour of using
+            ifStackTable.
+
+            Implementation of this table was optional.  It was
+            designed for those systems dividing a DS3/E3 into
+            channels containing different data streams that
+            are of local interest.
+
+            The DS3/E3 fractional table identifies which
+            DS3/E3 channels associated with a CSU are being
+            used to support a logical interface, i.e., an
+            entry in the interfaces table from the Internet-
+            standard MIB.
+
+            For example, consider a DS3 device with 4 high
+            speed links carrying router traffic, a feed for
+            voice, a feed for video, and a synchronous channel
+            for a non-routed protocol.  We might describe the
+            allocation of channels, in the dsx3FracTable, as
+            follows:
+            dsx3FracIfIndex.2. 1 = 3  dsx3FracIfIndex.2.15 = 4

+            For dsx3M23, dsx3 SYNTRAN, dsx3CbitParity, and
+            dsx3ClearChannel  there are 28 legal channels,
+            numbered 1 through 28.
