    DESCRIPTION
         "The MIB module to describe DS1, J1, E1, DS2, and
          E2 interfaces objects.

Copyright (c) The IETF Trust (2007).  This
          version of this MIB module is part of RFC 4805;
          see the RFC itself for full legal notices."
    REVISION "200703050000Z"
    DESCRIPTION
         "The following changes were made:
          (1) Values were added to dsx1LineType to
              support J1 types.
          (2) The object dsx1LineImpedance was added.
          (3) All DM-related objects were deprecated
              following their removal from ITU performance
              standards.
         The RFC 4805 version of this MIB module."
    REVISION "200409090000Z"
    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."

         "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."

            Making the object equal to ifIndex allows proper

Previously, this object was the identifier of a DS1
            interface on a managed device.  If there is an
            ifEntry that is directly associated with this and
            only this DS1 interface, it should have the same
            value as ifIndex.  Otherwise, number the
            dsx1LineIndices with a unique identifier
            following the rules of choosing a number that is
            greater than ifNumber and numbering the inside
            interfaces (e.g., equipment side) with even

            "This variable describes the variety of Zero Code
            Suppression used on this interface, which in turn
            affects a number of its characteristics.

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.

dsx1PayloadLoop

the received signal at this interface is looped

            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.

The dsx1LineStatus is a bitmap represented as a

dsx1NoAlarm must be set if and only if no other

If the dsx1loopbackState bit is set, the loopback
            in effect can be determined from the
            dsx1loopbackConfig object.  The various bit

-- The DS1 Fractional Table

dsx1FracTable OBJECT-TYPE
     SYNTAX  SEQUENCE OF Dsx1FracEntry
     MAX-ACCESS  not-accessible
     STATUS  deprecated
     DESCRIPTION
            "This table is deprecated in favor of using
            ifStackTable.

The table was mandatory for systems dividing a DS1
            into channels containing different data streams
            that are of local interest.  Systems that are
            indifferent to data content, such as CSUs, need
            not implement it.

The DS1 Fractional table identifies which DS1
            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 an application managing a
            North American ISDN Primary Rate link whose
            division is a 384-kbit/s H1 _B_ Channel for video,
            a second H1 for data to a primary routing peer,
            and 12 64-kbit/s H0 _B_ Channels.  Consider that
            some subset of the H0 channels is used for voice
            and the remainder are available for dynamic data
            calls.

We count a total of 14 interfaces multiplexed onto
            the DS1 interface.  Six DS1 channels (for the sake
            of the example, channels 1..6) are used for video,
            six more (7..11 and 13) are used for data, and the
            remaining 12 are in channels 12 and 14..24.

Let us further imagine that ifIndex 2 is of type
            DS1 and refers to the DS1 interface and that the
            interfaces layered onto it are numbered 3..16.

We might describe the allocation of channels, in
            the dsx1FracTable, as follows:
          dsx1FracIfIndex.2. 1 = 3  dsx1FracIfIndex.2.13 = 4
          dsx1FracIfIndex.2. 2 = 3  dsx1FracIfIndex.2.14 = 6
          dsx1FracIfIndex.2. 3 = 3  dsx1FracIfIndex.2.15 = 7
          dsx1FracIfIndex.2. 4 = 3  dsx1FracIfIndex.2.16 = 8
          dsx1FracIfIndex.2. 5 = 3  dsx1FracIfIndex.2.17 = 9
          dsx1FracIfIndex.2. 6 = 3  dsx1FracIfIndex.2.18 = 10
          dsx1FracIfIndex.2. 7 = 4  dsx1FracIfIndex.2.19 = 11
          dsx1FracIfIndex.2. 8 = 4  dsx1FracIfIndex.2.20 = 12
          dsx1FracIfIndex.2. 9 = 4  dsx1FracIfIndex.2.21 = 13
          dsx1FracIfIndex.2.10 = 4  dsx1FracIfIndex.2.22 = 14
          dsx1FracIfIndex.2.11 = 4  dsx1FracIfIndex.2.23 = 15
          dsx1FracIfIndex.2.12 = 5  dsx1FracIfIndex.2.24 = 16

For North American (DS1) interfaces, there are 24
            legal channels, numbered 1 through 24.

For G.704 interfaces, there are 31 legal channels,
            numbered 1 through 31.  The channels (1..31)
            correspond directly to the equivalently numbered
            time-slots."
