   2.  Abstract

   This document defines a standard SNMP MIB for additional functions
   not covered by the ADSL Line MIB [1].

   3.  The SNMP Network Management Framework



Expires March 2000                                              [Page 1]

INTERNET-DRAFT               ADSL Line MIB              October 20, 1999


   The SNMP Management Framework presently consists of five major
   components:

   o    An overall architecture, described in RFC 2571 [11].

   o    Mechanisms for describing and naming objects and events for
        the purpose of management.  The first version of this
        Structure of Management Information (SMI) is called SMIv1 and
        described in RFC 1155 [14], RFC 1212 [15] and RFC 1215 [16].
        The second version, called SMIv2, is described in RFC 2579
        [1], RFC 1903 [2] and RFC 1904 [17].

   o    Message protocols for transferring management information.
        The first version of the SNMP message protocol is called
        SNMPv1 and described in RFC 1157 [7].  A second version of
        the SNMP message protocol, which is not an Internet standards
        track protocol, is called SNMPv2c and described in RFC 1901
        [18] and RFC 1906 [19].  The third version of the message
        protocol is called SNMPv3 and described in RFC 1906 [19], RFC
        2272 [20] and RFC 2274 [21].

   o    Protocol operations for accessing management information.
        The first set of protocol operations and associated PDU
        formats is described in RFC 1157 [7].  A second set of
        protocol operations and associated PDU formats is described
        in RFC 1905 [8].

   o    A set of fundamental applications described in RFC 2273 [22]
        and the view-based access control mechanism described in RFC
        2275 [23].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This document specifies a MIB module that is compliant to the SMIv2.
   A MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
   translation is possible (e.g., use of Counter64).  Some machine
   readable information in SMIv2 will be converted into textual
   descriptions in SMIv1 during the translation process.  However, this
   loss of machine readable information is not considered to change the
   semantics of the MIB.

   Drafts of this document.  It will be deleted when the document is
   published as an RFC.

   The following changes were made for the version of the document dated
   October 20, 1999.

       - Changed adslLineExtTable to include config ATU-C, ATU-C and
   ATU-R actual transmission capabilities.
       - renamed adslProfileLineMode to adslProfileLineType to match
   rfc2662 adslLineType object.
       - Added two objects in the adslLineExtTable: one for
   adslLineModeConfig and adslLineModeActual.
       - Added a new textual convention for ADSL line mode.
       - Corrected the MIB compiled errors and typos.

   5.  Introduction

      The purpose of this memo is to define a supplemental set of
   managed objects that is not covered by ADSL Line MIB as defined in
   [10].  This memo addresses the additional objects defined in ITU
   G.997.1 [8].  These additional objects specifically address the
   management capabilities of ADSL "Lite" as defined by ITU-T G.992.2
   [9].

   6.  Relationship of the Supplemental ADSL LINE MIB with standard MIBs

   This section outlines the relationship of Supplemental ADSL Line MIB
   with other MIBs described in RFCs and in their various degrees of
   "standardization". Supplemental ADSL Line MIB obeys the same
   relationship between ADSL Line MIB to other standard MIBs with one
   exception for the ifOperStatus as defined in RFC 1213 [3].

   6.1 ifOperStatus

   ifOperStatus is set to down(2) when the ADSL line interface is in
   power state L2 which means no power.  ifOperStatus is set to up(1) if
   the ADSL line interface is in power state L0 (power on) or L1
   (reduced power).

   7.  Conventions used in the MIB

   7.1  Naming Conventions

   In addition to the naming conventions defined in the ADSL Line MIB
   [10] section 6.  This document defines the following naming
   conventions as well:

   A. Block Definition



Expires March 2000                                              [Page 3]

INTERNET-DRAFT               ADSL Line MIB              October 20, 1999


   ADSL Line MIB defines a "block" as "a physical-layer `data buffer'
   over which CRCs are calculated".

   ??

   7.2  Structure

   The MIB is organized to follow the same structure of the ADSL Line
   MIB [1].

   7.3  Additional Managed Objects

   A few objects are added to cover the ADSL "Lite" management and they
   are:

      - ATU-C Transmission System Capabilities
      - Power Management
      - Counters for Fast Retrains and Failed Fast Retrains
      - Counters for Severed Error Second-line and Unavailable Second
      - Clarify Definition of Blocks

      Besides the management of ADSL "Lite", another object needs to be
   added to the ADSL Line MIB [10] in order to manage the ADSL line
   profile.  The object is the line mode configuration.

      The MIB definitions are attached. The MIB will be branched from
   the ADSL Line MIB [10].

   7.3.1 ATU-C ADSL Transmission System Parameters

        The adslLineConfigTable needs to be extended to cover the ATU-C
   ADSL Transmission system enabling.  Objects are defined to enable the
   configuration and monitoring of the ATU-C and ATU-R transmission
   system capabilities as well as the actual ADSL transmission system
   being used.

   7.3.2 Power Management

        There are three power states for each managed ADSL interface.
   L0 is power on, L1 is power on but reduced and L2 is power off.
   Power state cannot be configured by an operator but it can be viewed
   via the ifOperStatus object for the managed ADSL interface.  The
   value of the object ifOperStatus is set to down(2) if the ADSL
   interface is in power state L2 and is set to up(1) if the ADSL line
   interface is in power state L0 or L1.

   7.3.3 Fast Retrain Parameters




Expires March 2000                                              [Page 4]

INTERNET-DRAFT               ADSL Line MIB              October 20, 1999


        Section 7.4.15 of ITU G.997.1 specifies fast retrain parameters.
   Fast retrain parameters include two counters: fast retrain count and
   failed fast retrain count.  These two counters need to be added to
   all performance tables.

   7.3.4 Counters for Severed Error Second-line and Unavailable Second

        Section 7.2.1.1.7 and section 7.2.1.1.9 specify two counters
   that are not covered by the ADSL Line MIB [10].  These two counters
   (severed error second-line and unavailable second) are added to all
   the performance tables.

        Unavailable second counts number of seconds when there was
   Unavailable Errored seconds during the measured period.  This counter
   does not include the seconds incurred by Fast Retrain and Failed Fast
   Retrain.  Fast Retrain and Failed Fast Retrain are considered to be
   part of normal network operation and thus are not counted as
   unavailable errors.

   7.3.5 Clarify Definition of Blocks

   Clarify block definition used by ADSL MIB is specified in section
   7.1.A.

   7.3.6 ADSL Line Mode configuration

   The adslLineConfProfileTable is extended to include a new object that
   allow operator to specify the line mode in a profile entry.

   module.
