1.  Abstract

  This document defines a standard SNMP MIB for ADSL lines based on the
  ADSL Forum standard data model [9].  The ADSL standard describes
  ATU-C and ATU-R as two sides of the ADSL line.  This MIB covers both
  ATU-C and ATU-R agent's perspectives.  Each instance defined in the

  MIB represents a single ADSL line.

  It should be noted that the ADSL Forum Network Management Working
  Group provided input towards the content of this document.  See the

  document possible.

2.  The SNMP Network Management Framework

  The SNMP Management Framework presently consists of five major
  components:

  o  An overall architecture, described in RFC 2571 [13].

  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 STD
     16, RFC 1155 [14], STD 16, RFC 1212 [15] and RFC 1215 [16].  The
     second version, called SMIv2, is described in STD 58, RFC 2578
     [1], STD 58, RFC 2579 [2] and STD 58, RFC 2580 [17].

  o  Message protocols for transferring management information.  The
     first version of the SNMP message protocol is called SNMPv1 and
     described in STD 15, 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 2572 [20] and RFC 2574
     [21].

  o  Protocol operations for accessing management information.  The
     first set of protocol operations and associated PDU formats is
     described in STD 15, 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 2573 [22] and
     the view-based access control mechanism described in RFC 2575
     [23].

  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.

RFC 2662                     ADSL Line MIB                   August 1999


3.  Object Definitions

  Managed objects are accessed via a virtual information store, termed
  the Management Information Base or MIB.  Objects in the MIB are
  defined using the extended subset of Abstract Syntax Notation One
  (ASN.1) defined in the SMI.  In particular, each object type is named
  by an OBJECT IDENTIFIER, an administratively assigned name.  The
  object type together with an object instance serves to uniquely
  identify a specific instantiation of the object.  For human
  convenience, we often use a textual string, termed the descriptor, to
  also refer to the object type.

4.  Relationship of the ADSL LINE MIB with standard MIBs

  This section outlines the relationship of ADSL Line MIB with other
  MIBs described in RFCs and in their various degrees of
  "standardization".

4.1  Use of the IfTable

  The ADSL LINE MIB specifies the detailed attributes of a data
  interface.  As such, it needs to integrate with IF-MIB [5].  The IANA
  has assigned the following ifType(s) relative to ADSL:

      IANAifType ::= TEXTUAL-CONVENTION

          . . .

      SYNTAX INTEGER {

               . . .

          adsl(94),    -- Asymmetric Digital Subscriber Loop

               . . .

          adslInterleave(124),    -- ADSL Interleaved Channel
          adslFast(125),          -- ADSL Fast Channel

               . . .          }

  Interfaces of each of these types are modeled by this document.  Most
  MIB tables in this document represent information of one of these
  interface types and are indexed by ifIndex.  Remaining are `profile'
  tables which may be accessed by the profileIndex.  This is explained
  in more detail in section 5.4 Profiles.





Bathrick & Ly               Standards Track                     [Page 3]

RFC 2662                     ADSL Line MIB                   August 1999


4.1.1  ADSL Interface Types

  As shown below, three ADSL interface types are defined in this
  document, namely physical, interleaved channel, and fast channel.
  The physical interface represents characteristics of the physical
  media associated with both the ATUC and ATUR.  The interleaved and
  fast channel interface represent the characteristics of the two types
  of ADSL channels.

  For each ADSL Line, a physical interface always exists.   Depending
  on which ADSL operational configuration is present (as listed in
  Figure 5), the channel interfaces (fast or interleaved) may or may
  not exist.

              ______                      ______
             |      |____________________|      |
             | ATUC |                    | ATUR |
             |      |____________________|      |
             |______|                    |______|

                | <----- physical --------> |

                | <--- fast channel ------> |

                | <- interleaved channel -> |

                     Figure 1: ADSL Model

4.1.2  Use of IF-MIB  (Interface MIB RFC 2233) [5]

  The following attributes are part of the required
  ifGeneralInformationGroup object group specified in RFC 2233 [5], and
  are not duplicated in the ADSL MIB.  Keep in mind that these objects
  apply to the agent's view of the line.

       Figure 2: Use of ifTable Objects: ifGeneralInformationGroup

  Use of the ifStackTable to associate the entries for physical, fast,
  interleaved channels, and higher layers (e.g., ATM) is shown below in
  figure 3.  Use of ifStackTable is necessary, because configuration
  information is stored in profile tables associated with the
  physical-layer ifEntry only.  The channels' ifEntrys need the
  ifStackTable to find their associated physical-layer entry and thus
  their configuration parameters.  (See Profile section, 5.4).

  The ifStackTable is then used to show the relationships between the
  various ADSL interfaces, as illustrated below in figure 4.

RFC 2662                     ADSL Line MIB                   August 1999


4.2  Relationship with RFC 2037 [25]

  Implementation of the Entity MIB [25] is optional.  It in no way
  alters the information required in the adslLineMib, nor does it alter
  the relationship with IF-MIB.

  The Entity MIB introduces a standardized way of presenting the
  components of complex systems, such as a Digital Subscriber Line
  Access Multiplexer (DSLAM), that may contain multiple racks, shelves,
  line cards, and/or ports.   The Entity MIB's main goal is to present
  these system components, their containment relationship, and mapping
  information with other MIBs such as the Interface MIB and the
  adslLineMib.

  If ATU-C agent is implemented, the Entity MIB should include entities
  for the ATU-C in the entPhysicalTable.  The MIB's
  entAliasMappingTable would contain mapping information identifying
  the 'ifIndex' object associated with each ATU-C.  However, if ATU-R
  agent is implemented, the Entity MIB should include entities for the
  ATU-R in the entPhysicalTable.  In this case, the MIB's
  entAliasMappingTable would  contain mapping information identifying
  the 'ifIndex' object associated with each ATU-R.

  Also associating the relationship between the ifTable and Entity MIB,
  the entPhysicalTable contains an 'entPhysicalName' object, which
  approximates the semantics of the 'ifName' object from the Interface
  MIB.

5.  Conventions used in the MIB

5.1  Naming Conventions

  A. Atuc/Atur are used for the ATU-C and ATU-R.  In other RFCs, these
     are sometimes referred to as the Near End (Ne) and Far End (Fe)
     respectively, but not in this document.

  B. The terms, "transmit" and "receive", are from the perspective of
     the corresponding table's end of the line.  For example, in the
     case of Fast channels, adslAtucChanConfFastMaxTxRate defines the
     "downstream" rate, while adslAturChanConfFastMaxTxRate defines the
     "upstream" rate for a particular channel.

  C. There are two possible channels: fast, and interleaved.  None, one
     or both may be implemented on a particular ADSL Line.  Figure 5
     illustrates all possible operational configurations.






Bathrick & Ly               Standards Track                     [Page 7]

RFC 2662                     ADSL Line MIB                   August 1999


  D. Lof, Lol, Los, Lpr mean Loss of Framing, Link, Signal, and Power,
     respectively.  Lpr is used by T1E1, so it is used for consistency
     (rather than Lop).

     A Loss of Link condition is declared at the ATU-C if a Loss of
     Signal is not preceded by a `dying-gasp' message from the ATU-R.
     Note that Loss of Link is only supported by the ATU-C.

  E. ES means errored second. An Errored Second is any second
     containing one or more CRC anomaly, or one or more Los(s) or
     Severely Errored Frame (Sef) defect(s).

  F. A "block" is a physical-layer `data buffer' over which CRCs are
     calculated.  For example, in DMT, the block is defined as the ADSL
     superframe.  The block duration is 250 micro-seconds so the block
     length in bytes, as defined in adslAtu*ChanCrcBlockLength, varies
     with data rate.  See Line Code Specific MIBs [11] [12] for more
     line code specific information.

  G. Atn means Attenuation, Psd is Power Spectral Density and Snr is
     Signal to Noise Ratio.

  H. LCS means line code specific, e.g.,

     o DMT = Discrete MultiTone

     o CAP = Carrierless Amplitude and Phase modulation and

     o QAM = Quadrature Amplitude Modulation

  I. Vendor (in the Inventory objects) refers to the manufacturer of
     the ATU-C or ATU-R assembly, not the modem chip vendor. When in
     doubt, use the manufacturer of the smallest field replaceable unit
     (e.g., stand-alone modem box, plug-in board).

  J. RADSL - Rate Adaptive Asymmetric Digital Subscriber Loop

5.2  Structure

  The MIB has multiple parallel tables.  There are tables for:

     o line -  common attributes

     o atuc and atur status







Bathrick & Ly               Standards Track                     [Page 8]

RFC 2662                     ADSL Line MIB                   August 1999


     o atuc and atur performance

        - Current and up to 96 buckets of 15 min performance history

        - Current and Previous 1-day bucket performance history

     o profiles - configuration parameters and alarm parameters

  There are separate tables for Physical and Channel layers.  Since
  their attributes are similar, only one set of "channel" tables are
  defined to be used for both fast and interleaved channels. The
  corresponding ifType gives the proper interpretation for that
  ifEntry.

  It is intented that Line Code Specific MIBs be located under
  adslLCSMib.  These MIBs will be defined in separate modules.

  There could have been fewer tables by combining the ATU-C and ATU-R
  information into shared tables. However, the tables are more easily
  read when there are two identical sets of data.

  The figure below lists the five possible ADSL operational
  configurations. (indicated by the value of the adslLineType).  In all
  configurations, the physical line interface entry will exist.
  However, the existence of the ADSL channel varies in each case, as
  shown below.

      Table                         Phys     Fast  Interleaved
  ___________________________________________________________
    No Channels (1)               |  Y    |        |        |
    Fast Only (2)                 |  Y    |   Y    |        |
    Interleaved Only (3)          |  Y    |        |   Y    |
    Fast or Interleaved (4)       |  Y    |   Y    |   Y    |
    Fast and Interleaved (5)      |  Y    |   Y    |   Y    |

             Figure 5: ADSL Operational configurations

  NOTE: In (4), channel exists of either Fast or Interleaved type, but
  not both.   The Manager may select the type of channel to be used.

  Depending on which operation configuration exists, some or all ADSL
  MIB tables could be supported, as shown in below.  See Conformance
  Statements for more information on which objects are mandatory.

  document for implementation details such as profile creation,
  assignment, and indexing.

5.2.1 Structure of Conformance Groups

  The MIB is organized to cover both ends of the ADSL line, ATU-C and
  ATU-R.  Objects defined can be categorized into two groups:  the
  ATU-C group which provides objects that are supported by ATU-C agents
  and the ATU-R group which provides objects that are supported by
  ATU-R agents.  These two groups are defined by the conformance
  section of the MIB.  All objects defined in the MIB module are
  supported by the ATU-C agent and only portions of the objects are
  supported by the ATU-R agent.  Figure 7 lists all tables/objects that
  are supported by the ATU-R agent.

  attempts, there are event counters, current 15-minute and one (up to
  96) 15-minute history bucket(s) of "interval-counters", as well as
  current and previous 1-day interval-counters.  Each physical-layer
  current 15-minute event bucket has threshold trap.

  At the channel level, there are counters for total received blocks,
  received-and-corrected blocks, received-but-uncorrectable blocks, and
  transmitted blocks. There are the same set of 15-minute and 1-day
  buckets as at the physical-layer.

  There is no requirement for an agent to ensure fixed relationship
  between the start of a fifteen minute and any wall clock; however
  some implementations may align the fifteen minute intervals with
  quarter hours.  Likewise, an implementation may choose to align one
  day intervals with start of a day.

  Separate tables are provided for the 96 interval-counters. They are
  indexed by {ifIndex, AdslAtu*IntervalNumber}.

  Counters are not reset when an ATU-C or ATU-R is reinitialized, only
  when the agent is reset or reinitialized (or under specific request
  outside the scope of this MIB).

  The 15-minute event counters are of type PerfCurrentCount and
  PerfIntervalCount.  The 1-day event counters are of type
  AdslPerfCurrDayCount and AdslPerfPrevDayCount. Both 15-minute and 1-
  day time elapsed counters are of type AdslPerfTimeElapsed.

5.4  Profiles

  As a managed node can handle a large number of ATU-Cs (e.g., hundreds
  or perhaps thousands of ADSL lines), provisioning every parameter on
  every ATU-C may become burdensome.  In response, two MIB tables have
  been created to define ADSL equipment configuration data profiles, as
  well as a mechanism to associate the equipment to these profiles.

  Profile tables may be implemented in one of two ways, but not
  simultaneously:

     o  MODE-I: Dynamic Profiles - one profile shared by one or
        multiple ADSL lines.

     o  MODE-II: Static Profiles - one profile per ADSL physical line
        always.

5.4.1  MODE-I : Dynamic Profiles

  Implementations using this mode will enable the manager to
  dynamically create and delete profiles as needed.  The index of the
  profile is an locally-unique administratively assigned name for the
  profile having the textual convention `SnmpAdminString' (RFC2571
  [13]).

  One or more ADSL lines may be configured to share parameters of a
  single profile (e.g., adslLineConfProfileName = `silver') by setting
  its adslLineConfProfile objects to the index value of this profile.
  If a change is made to the profile, all lines that refer to it will
  be re-configured to the changed parameters.  Before a profile can be
  deleted or taken out of service it must be first unreferenced from
  all associated lines.

  This figure below shows an example of how this mode can be
  implemented.  In the example, ADSL lines `1' and `x' share the
  configuration of the `silver' profile, while line `2' uses the
  `platinum' profile.  The `gold' profile has no lines associated with
  it.

  __________________________________________________________________

              Figure 8: Use of Dynamic Profiles: MODE-I

  In the figure above, note that three interface entries of an ADSL
  line, physical, fast channel, and interleaved channel, are
  represented by `i', `j', and `k'.  Only the physical-layer entry `i'
  contains an adslLineTable entry, therefore only those entries contain
  pointers to the adslLineConfProfileTable.  The ifStackTable (see
  rfc2233 [5]) can be used to link the channel entries to the
  corresponding physical-layer entry to get the channel's configuration
  parameters.  See figure 4 for use of the ifStackTable.

  The same characteristics and mechanisms are present for the alarm
  profile type. There is no requirement that its index be the same as
  the configuration profile.

  Implementations of this mode, must provide a default profile whose
  name is `DEFVAL' for each profile type: Configuration and Alarm.  The
  values of the associated parameters will be vendor specific unless
  otherwise indicated in this document.  Before a line's profiles have
  been set, these profiles will be automatically used by setting
  adslLineConfProfile and adslLineAlarmConfProfile to `DEFVAL'.







Bathrick & Ly               Standards Track                    [Page 14]

RFC 2662                     ADSL Line MIB                   August 1999


  In this mode, profiles are created, assigned, and deleted dynamically
  using these four objects: adslLineConfProfile,
  adslLineConfProfileRowStatus, adslLineAlarmConfProfile,  and
  adslLineAlarmConfProfileRowStatus.

5.4.2  MODE-II : Static Profiles

  Implementations with this mode will automatically create a profile
  one-for-one with each ADSL line physical entry.  The name of this
  profile is a system generated read-only object whose value is
  equivalent to the index of the physical line.  The Agent will not
  allow a Manager to create/delete profiles in this mode.  Therefore,
  adslLineConfProfile, adslLineConfProfileRowStatus,
  adslLineAlarmConfProfile, and adslLineAlarmConfProfileRowStatus
  objects have minimal value in this mode and are read-only.

  The figure below shows an example of this mode. In the example, ADSL
  lines `1', `2', and `x' each have their own profiles.

5.5  Traps

  These SNMP traps are required: coldStart / warmStart (per [6]) --
  which are per agent (e.g., per DSLAM in such a device), and linkUp /
  linkDown (per [5]) -- which are per interface (i.e., ADSL line).
  Note: RFC 2233 [5] recommends that linkUp / linkDown only be used at
  a physical-layer ifEntry, as discussed above.





Bathrick & Ly               Standards Track                    [Page 15]

RFC 2662                     ADSL Line MIB                   August 1999


  A linkDown trap is generated whenever any of Lof, Los, Lol, Loss of
  Signal Quality, or Lpr events occurs.  At this operational point, a
  manager can use adslAtu*CurrStatus for additional detailed
  information. The corresponding linkUp trap is sent when all link
  failure conditions are cleared.

  The traps defined in this MIB are for initialization failure, rate
  change, and for the threshold crossings associated with the following
  events: Lofs, Lols, Loss, Lprs, and ESs.  Each threshold has its own
  enable/threshold value. When that value is 0, the trap is disabled.

  The current status objects (adslAtu*CurrStatus) indicate, through a
  bitmask, all outstanding error conditions or that the line is
  operational.  Note that each object claims to represent the status of
  the modem at that end of the line.  However, since the SNMP agent
  likely co-resides with only one end of the line, the corresponding
  far-end current status object may be incomplete. For example, when
  there are errors on the line, the far-end ATU may not be able to
  correctly report this condition. Therefore, not all conditions are
  included in its current status.

  A threshold trap occurs whenever the corresponding current 15-minute
  interval error counter becomes equal and/or exceeds to the threshold
  value.  One trap will be sent per interval per interface. Since the
  current 15-minute counter are reset to 0 every 15 minutes, if the
  condition persists, the trap may recur as often as every 15 minutes.
  For example, to get a trap whenever a "loss of" event occurs (but at
  most once every 15 minutes), set the corresponding "Thresh15Min" to
  1.  The agent will generate a trap when the event originally occurs.

  Note that the NMS will get a linkDown trap, as well, if enabled.  At
  the beginning of the next 15 minute interval, the counter is reset.
  When the first second goes by and the event occurs, the current
  interval bucket will be 1, which equals the threshold and the trap
  will be sent again.

  The rate change trap is invoked when the transmit rate on a channel
  either increases by adsl(x)Thresh(y)RateUp or decreases by
  adsl(x)Thresh(y)RateDown. The trap is per direction:(x) == Atuc or
  Atur, and per channel: (y) == Fast or Interleave. In other words, the
  trap is sent whenever the rate changes in either direction on either
  channel and:

               CurrTxRate >= PrevTxRate plus ThreshRateUp

                                   or

              CurrTxRate <= PrevTxRate minus ThreshRateDown



Bathrick & Ly               Standards Track                    [Page 16]

RFC 2662                     ADSL Line MIB                   August 1999


  No trap is sent on initialization.

  It can be disabled by setting the Up (and/or) Down threshold rates to
  0.

  The PrevTxRate object is set to the current value at initialization
  and when a trap is sent.  Thus rate changes are cumulative until the
  total change reaches the threshold.

                "Interleave Delay for this channel.

                Interleave delay applies only to the

                (relative spacing) between subsequent input
                bytes at the interleaver input and their placement
                in the bit stream at the interleaver output.
                Larger numbers provide greater separation between
                consecutive input bytes in the output bit stream
                allowing for improved impulse noise immunity at
                the expense of payload latency.

10.  Security Considerations

  1) Blocking unauthorized access to the ADSL MIB via the element
  management system is outside the scope of this document. It should be
  noted that access to the MIB permits the unauthorized entity to
  modify the profiles (sect 6.4) such that both subscriber service and
  network operations can be interfered with. Subscriber service can be
  altered by modifying any of a number of service characteristics such
  as rate partitioning and maximum transmission rates. Network
  operations can be impacted by modification of trap thresholds such as
  SNR margins.

  2) There are a number of managed objects in this MIB that may be
  considered to contain sensitive information.  In particular, the
  certain objects may be considered sensitive in many environments,
  since it would allow an intruder to obtain information about which
  vendor's equipment is in use on the network.  Therefore, it may be
  important in some environments to control read access to these
  objects and possibly to even encrypt the values of these object when
  sending them over the network via SNMP.  Not all versions of SNMP
  provide features for such a secure environment.

  SNMPv1 by itself is such an insecure environment.  Even if the
  network itself is secure (for example by using IPSec), even then,
  there is no control as to who on the secure network is allowed to
  access and GET (read) the objects in this MIB.  It is recommended
  that the implementors consider the security features as provided by
  the SNMPv3 framework.  Specifically, the use of the User-based
  Security Model RFC 2574 [21] and the View-based Access Control Model
  RFC 2575 [23] is recommended.

  It is then a customer/user responsibility to ensure that the SNMP
  entity giving access to an instance of this MIB, is properly
  configured to give access to those objects only to those principals
  (users) that have legitimate rights to access them.

  3) ADSL layer connectivity from the ATU-R will permit the subscriber
  to manipulate both the ADSL link directly and the AOC/EOC channels
  for their own loop.  For example,  unchecked or unfiltered
  fluctuations initiated by the subscriber could generate sufficient
  traps to potentially overwhelm either the management interface to the
  network or the element manager.  Other attacks affecting the ATU-R
  portions of the MIB may also be possible.
