          (1) Values were added to dsx1LineType to

              support J1 types.

          (2) The object dsx1LineImpedance was added.

    DESCRIPTION

         "The RFC 3895 version of this MIB module.

          The key changes made to this MIB module

          since its publication in RFC 2495 are as follows:

     (1) The dsx1FracIfIndex SYNTAX matches the description

         range.

     (2) A value was added to dsx1TransmitClockSource.

     (3) Values were added to dsx1LineType.

     (4) Two objects were added, dsx1LineMode and

         dsx1LineBuildOut, to better express transceiver

         mode and LineBuildOut for T1.

     (5) Reference was added to Circuit Identifier object.

     (6) Align the DESCRIPTION clauses of few statistic

         objects with the near-end definition, with the far-end

         definition, and with RFC 3593.

     (7) Changes in Compliance Statements to include new

         objects.

     (8) A typographical error in dsx2E2 was fixed; the new name

         is dsx1E2."

    DESCRIPTION

         "The RFC 2495 version of this MIB module.

          The key changes made to this MIB module

          since its publication in RFC 1406 are as follows:

     (1)  The Fractional table has been deprecated.

     (2)  This document uses SMIv2.

     (3)  Usage is given for ifTable and ifXTable.

     (4)  Example usage of ifStackTable is included.

     (5)  dsx1IfIndex has been deprecated.

     (6)  Support for DS2 and E2 has been added.

     (7)  Additional lineTypes for DS2, E2, and unframed E1

          were added.

     (8)  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.

     (9)  An inward loopback has been added.

     (10) Additional lineStatus bits have been added for Near

          End in Unavailable Signal State, Carrier Equipment

          Out of Service, DS2 Payload AIS, and DS2 Performance

          Threshold.

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

     (12) Signal mode of other has been added.

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

     (14) The e1(19) ifType has been obsoleted, so this MIB

          does not list it as a supported ifType.

     (15) Textual Conventions for statistics objects have

          been used.

     (16) A new object, dsx1LoopbackStatus, has been

          introduced to reflect the loopbacks established

          on a DS1 interface and the source to the requests.

          dsx1LoopbackConfig continues to be the desired

          loopback state while dsx1LoopbackStatus reflects

          the actual state.

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

          of an inward loopback and a line loopback at the

          same time.

     (18) An object indicating which channel to use within a

          parent object (i.e., DS3) has been added.

     (19) An object has been added to indicate whether or

          not this DS1/E1 is channelized.

     (20) Line coding type of B6ZS has been added for DS2."

            dsx1JBZS refers the Jammed Bit Zero Suppression,

            in which the AT&T specification of at least one

            pulse every 8-bit period is literally implemented

            by forcing a pulse in bit 8 of each channel.

            Thus, only 7 bits per channel, or 1.344 Mbps,

            are available for data.

            dsx1B8ZS refers to the use of a specified pattern

            of normal bits and bipolar violations that are

            used to replace a sequence of 8 zero bits.

            ANSI Clear Channels may use dsx1ZBTSI, or Zero

            Byte Time Slot Interchange.

            E1 links, with or without CRC, use dsx1HDB3 or

            dsx1AMI.

            dsx1AMI refers to a mode wherein no Zero Code

            Suppression is present and the line encoding does

            not solve the problem directly.  In this

            application, the higher layer must provide data

            that meets or exceeds the pulse density

            requirements, such as inverting HDLC data.

            dsx1B6ZS refers to the user of a specified pattern

            of normal bits and bipolar violations that are

            used to replace a sequence of 6 zero bits.  Used

            for DS2.

            "This variable represents the desired loopback

            supporting read/write access should return

            inconsistentValue in response to a requested

            support.  The values mean:

      dsx1NoLoop

            not in the loopback state.  A device that is not

            capable of performing a loopback on the interface

            shall always return this as its value.

      dsx1PayloadLoop

            the received signal at this interface is looped

            through the device.  Typically, the received signal

            is looped back for retransmission after it has

            passed through the device's framing function.

      dsx1LineLoop

            the received signal at this interface does not go

            through the device (minimum penetration) but is

            looped back out.

      dsx1OtherLoop

            loopbacks that are not defined here.

      dsx1InwardLoop

            the transmitted signal at this interface is

            looped back and received by the same interface.

            What is transmitted onto the line is product

            dependent.

      dsx1DualLoop

            received alarm and transmitted alarms

            information.

            The dsx1LineStatus is a bitmap represented as a

            sum; therefore, it can represent multiple failures

            (alarms) and a LoopbackState simultaneously.

            dsx1NoAlarm must be set if and only if no other

            flag is set.

            If the dsx1loopbackState bit is set, the loopback

            in effect can be determined from the
