    DESCRIPTION
         "The MIB module to describe
         SONET/SDH interfaces objects."





    REVISION      "9810190000Z"
    DESCRIPTION
        "The key changes made to this MIB module
        since its initial publication in RFC 1595
        are as follows.

        (1) The MODULE-IDENTITY has been updated to reflect the
            changes to the MIB.

        (2) Where applicable, the textual conventions
            PerfCurrentCount and PerfIntervalCount from
            PerfHist-TC-MIB have been used in place of Gauge32.

        (3) An agent now has the option to delay updates to
            the various performance counts in lieu of performing
            retroactive adjustments upon entering into or exiting
            from unavailable time. This implementation option is
            described in Appendix A of this memo.

        (4) In order to make the SONET-MIB more useful for
            circuit provisioning, the formerly read-only objects
            sonetMediumType, sonetMediumLineCoding,
            sonetMediumLineType, and sonetMediumCircuitIdentifier
            have been given a MAX-ACCESS of read-write. The
            MIN-ACCESS remains read-only.

        (5) The DESCRIPTION clause for sonetMediumTimeElapsed has
            been updated to describe its behaviour if the duration
            of the current interval exceeds the maximum value.

        (6) The DESCRIPTION clause for sonetMediumValidIntervals
            has been updated to describe its behaviour when some
            intervals may be unavailable, and the object
            sonetMediumInvalidIntervals has been added to keep
            count of the number of missing intervals (if any).

        (7) The object sonetMediumLoopbackConfig has been added
            to enable or disable loopback configurations.

        (8) Because the error count thresholds for declaring
            severely errored seconds that are specified in ANSI
            T1.231-1993, ITU-T G.826-1995, and ANSI T1.231-1997
            are all different from each other and from the thresholds
            specified in RFC 1595, an enumerated INTEGER object
            sonetSESthresholdSet has been added to allow an agent
            to specify which threshold set is in use. Text has
            been added to Section 3 stating that if this object is
            not implemented the thresholds specified in RFC 1595





            should be assumed, and the table containing those
            thresholds has been moved to Appendix B of this memo.

        (9) A column with SYNTAX TruthValue has been added to each
            interval table.  The purpose of the additional column
            is to indicate, for each interval, whether the data
            is valid in the sense intended by ANSI T1.231 clause
            9.1.2.2 [31][35]. The objects in question are:

                sonetSectionIntervalValidData
                sonetLineIntervalValidData
                sonetFarEndLineIntervalValidData
                sonetPathIntervalValidData
                sonetFarEndPathIntervalValidData
                sonetVTIntervalValidData
                sonetFarEndVTIntervalValidData

       (10) The ranges for sonetPathCurrentStatus and
            sonetVTCurrentStatus have been made consistent
            with the DESCRIPTION clauses.

       (11) The conformance information has been updated. Previous
            conformance information from RFC 1595 has been
            deprecated. Some typographical errors in the deprecated
            section have been corrected in order to prevent
            MIB compilation errors."
