RFC 3440 ADSL Line Extension MIB December 2002
1. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
2. Introduction
The purpose of this memo is to define a supplemental set of managed
objects that is not covered by the ADSL Line MIB as defined in
[RFC2662]. This memo addresses the additional objects defined in ITU
G.997.1 [ITU G.997.1].
3. Relationship of ADSL Line Extension MIB with standard MIBs
This section outlines the relationship of the ADSL Line Extension MIB
with other MIBs described in RFCs and in their various degrees of
standardization. In regards to these relationships, the ADSL Line
Extension MIB follows conventions as used by the ADSL Line MIB with
one exception. The value of the RFC 2863 object, ifOperstatus, SHALL
be down(2) when the ADSL line interface is in power state L3, as
defined in ITU G.992.1 [ITU G.992.1], which means no power. Its
value shall be up(1) if the ADSL line interface is in power state L0
(power on) [ITU G.992.1] or L1 (reduced power). Power Status L2 [ITU
G.992.1] is not applicable.
4. Conventions used in the MIB
4.1 Structure
The MIB is organized to follow the same structure of the ADSL Line
MIB [RFC2662].
Ly & Bathrick Standards Track [Page 2]
RFC 3440 ADSL Line Extension MIB December 2002
4.2 Additional Managed Objects
Objects specific to the management of ADSL G.Lite as defined in ITU
G.992.2 [ITU G.992.2] are:
- ADSL Transceiver Unit - Central Office End (ATU-C)
Transmission System and Line Mode
- Power Management
- Counters for Fast Retrains and Failed Fast Retrains
- Counters for Severe Error Second-line and Unavailable Second
- Alternative profile configuration for the Dual line mode
interface
Besides the management of G.Lite, another object has been added in
order to manage the ADSL line profile. The object is the line mode
configuration.
4.2.1 ATU-C ADSL Transmission System Parameters and Line Mode
The adslLineConfigTable needs to be extended to cover control of the
ATU-C ADSL Transmission system. Three objects are defined to monitor
and configure the transmission mode as well as the actual line mode:
- Capability
- Configuration
- Actual Status
Transmission modes can further determine the line mode of the ADSL
interface. For example, if g9921PotsNonOverlapped(2) is the actual
value of the ADSL interface, the interface is operating in Full rate
ADSL. If the interface is set to g9922PotsOverlapped(9), the
interface is operating in G.Lite mode.
Ly & Bathrick Standards Track [Page 3]
RFC 3440 ADSL Line Extension MIB December 2002
The transmission mode and the corresponding line mode are defined as:
Transmission mode Line Mode
----------------------------------------------------------
Regional Std. (ANSI T1.413) Full
[ANSI T1.413]
Regional Std. (ETSI DTS/TM06006) Full
[ETSI DTS/TM06006]
G.992.1 [ITU G992.1] POTS non-overlapped Full
G.992.1 POTS overlapped Full
G.992.1 Integrated Services Digital
Network (ISDN) non-overlapped Full
G.992.1 ISDN overlapped Full
G.992.1 TCM-ISDN non-overlapped Full
G.992.1 TCM-ISDN overlapped Full
G.992.2 POTS non-overlapped G.Lite
G.992.2 POTS overlapped G.Lite
G.992.2 with TCM-ISDN G.Lite
non-overlapped
G.992.2 with TCM-ISDN overlapped G.Lite
G.992.1 TCM-ISDN symmetric Full
Table 1: Transmission Mode and Line Mode
In case more than one bit is configured for an ADSL interface and
both Full and G.Lite modes are selected, the interface is said to be
configured in the dual mode. Only one bit can be set in the Actual
object that reflects the actual mode of transmission as well as the
line mode.
4.2.2 Power Management
There are three possible power states for each managed ADSL interface
operating in the G.Lite mode. L0 is power on, L1 is power on but
reduced and L3 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 L3 and is set to
up(1) if the ADSL line interface is in power state L0 or L1.
An ADSL line power state, if the interface is operating in the G.Lite
mode, can also be monitored by the adslLineGlitePowerState object
defined in the ADSL Line Extension table. The value of the object
enumerates the three power states attainable by the managed
interface.

RFC 3440 ADSL Line Extension MIB December 2002
4.2.3 Fast Retrain Parameters
Section 7.4.15 [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 have been added to all
performance tables.
4.2.4 Counters for Severely Errored Second-line and Unavailable
Seconds-line
ITU G.997.1 sections 6.2.1.1.7 and 6.2.1.1.9 specify two counters
that are not covered by the ADSL Line MIB [RFC2662]. These two
counters (severely errored seconds-line and unavailable seconds-line)
are added to all the performance tables.
Unavailable seconds counts the cumulative number of seconds in which
the interface was unavailable during the measured period. This
counter does not include the seconds in which unavailability was
caused solely by fast retrains and failed fast retrains. Fast
retrains and failed fast retrains are considered to be part of the
normal network operation and thus are not counted as unavailable
errors.
4.2.5 Counters, Interval Buckets and Thresholds
For physical-level events, there are 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. Threshold
notification can be configured for each physical-layer current 15-
minute bucket.
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 the type PerfCurrentCount and
PerfIntervalCount. The 1-day event counters are of the type
AdslPerfCurrDayCount and AdslPerfPrevDayCount. Both 15-minute and 1-
day time elapsed counters are of the type AdslPerfTimeElapsed.
Ly & Bathrick Standards Track [Page 5]
RFC 3440 ADSL Line Extension MIB December 2002
4.2.6 Alternative profile configuration for the dual line mode interface
The object, adslLineConfProfileDualLite, is used only when the
interface (the ADSL line and, if applicable, channel) is configured
as dual mode, that is, the object adslLineTransAtucConfig is
configured with one or more full-rate modes and one or more G.Lite
modes.
The object adslLineConfProfile defined in ADSL-MIB [RFC2662] is used
as the primary full-rate profile. The newly added object in this MIB
module, adslLineConfProfileDualLite, is used to describe and
configure the G.Lite profile. Note that if one or more full-rate
modes are configured, or only G.Lite modes are configured, only the
original full-rate profile is needed. The dual-mode profile object
is only needed when both full-rate and G.Lite profiles are needed.
In this case, it will be set to the value of adslLineConfProfile when
'dynamic' profiles are implemented.
When 'static' profiles are implemented, however, similar to the case
of the object, adslLineConfProfileName [RFC2662], this object's value
will need to algorithmically represent the line. In this case, the
value of the line's ifIndex plus a value indicating the line mode
type (e.g., G.Lite, Full-rate) will be used. Therefore, the
profile's name is a string of the concatenation of the ifIndex and
one of the following values: Full or Lite. This string will be
fixed-length (i.e., 14) with leading zero(s). For example, the
profile name for ifIndex that equals '15' and is a full rate line
will be '0000000015Full'.

DESCRIPTION
"This object extends the definition an ADSL line and
associated channels (when applicable) for cases
when it is configured in dual mode, and operating
in a G.Lite-type mode as denoted by
adslLineTransAtucActual. Dual mode exists when the
object, adslLineTransAtucConfig, is configured with
one or more full-rate modes and one or more G.Lite
modes simultaneously.
When 'dynamic' profiles are implemented, the value
of object is equal to the index of the applicable
row in the ADSL Line Configuration Profile Table,
AdslLineConfProfileTable defined in ADSL-MIB
[RFC2662].
In the case when dual-mode has not been enabled,
the value of the object will be equal to the value
of the object adslLineConfProfile [RFC2662].
When `static' profiles are implemented, in much
like the case of the object,
adslLineConfProfileName [RFC2662], this object's
value will need to algorithmically represent the
characteristics of the line. In this case, the
value of the line's ifIndex plus a value indicating
the line mode type (e.g., G.Lite, Full-rate) will
be used. Therefore, the profile's name is a string
concatenating the ifIndex and one of the follow
values: Full or Lite. This string will be
fixed-length (i.e., 14) with leading zero(s). For
example, the profile name for ifIndex that equals
'15' and is a full rate line, it will be
'0000000015Full'."

9. Security Considerations
The following security matters should be considered when implementing
this MIB.
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 (section 6.4) such that both
subscriber service and network operations can be interfered with.
Ly & Bathrick Standards Track [Page 32]
RFC 3440 ADSL Line Extension MIB December 2002
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
modifying notification thresholds such as Signal-to-Noise Ratio
(SNR) margins.
2) SNMPv1 by itself is such an insecure environment. Even if the
network itself is secure (for example by using IPSec), there is no
control over 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 STD 62, RFC 3414 [RFC3414] and the View-based
Access Control Model STD 62, RFC 3415 [RFC3415] 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 only those objects, and to those
principals (users) that have legitimate rights to access them.
3) The profile mechanism presented in this document requires specific
attention. The implementor of this MIB has a choice of
implementing either 'static' or 'dynamic' profiles. This decision
must be consistent with the implementation of RFC 2662.
In the case of 'static' profiles, the elements of the profile are
read-write, as opposed to read-create when 'dynamic' profiles are
implemented:
- adslConfProfileLineType,
- adslAtucThreshold15MinFailedFastR,
- adslAtucThreshold15MinSesL,
- adslAtucThreshold15MinUasL,
- adslAturThreshold15MinSesL, and
- adslAturThreshold15MinUasL.
This decision also impacts the mechanics of the index,
adslLineConfProfileDualLite. When 'static' profiles are
implemented, its value is algorithmically set by the system and
its value is based on the ifIndex. Hence it is not guaranteed
across system reboots. Similar to the handling of
adslLineConfProfile [RFC2662], the implementor of this MIB must
ensure that the profile object values associated with these
indices are maintained across system reboots.
Ly & Bathrick Standards Track [Page 33]
RFC 3440 ADSL Line Extension MIB December 2002
In the case of dynamic profiles, this object is set by the SNMP
manager. The implementor of this MIB may want to provide a view
of the profile on a customer-by-customer standpoint, but should be
cautious of the dynamic nature of these objects.
4) ADSL layer connectivity from the ATU-R will permit the
subscriber to manipulate both the ADSL link directly and the ADSL
overhead control channel(AOC)/embedded operations channel (EOC)
for their own loop. For example, unchecked or unfiltered
fluctuations initiated by the subscriber could generate sufficient
notifications 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.
