Abstract
This document defines a portion of the Management Information Base
(MIB) module for use with network management protocols in the
Internet community. In particular, it describes objects used for
managing the Line Code Specific parameters of Very High Speed
Digital Subscriber Line (VDSL) interfaces using Multiple Carrier
Modulation (MCM) Line Coding. It is an optional extension to the
VDSL-LINE CORE MIB RFC XXXX [RFCXXXX] which handles the line code
independent objects.

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. Overview
This document describes an SNMP MIB module for managing the line
code dependent (Physical Medium Dependent) Layer of MCM VDSL Lines.
These definitions are based upon the specifications for VDSL as
defined in T1E1, ETSI, and ITU documentation [T1E1311, T1E1011,
T1E1013, ETSI2701, ETSI2702, ITU9931, ITU9971]. Additionally the
protocol-dependent (and line-code dependent) management framework
for VDSL lines specified by DSLF has been taken into consideration
[DSLFXXXXXX].
The MIB module is located in the MIB tree under MIB 2 transmission,
as discussed in the MIB-2 Integration (RFC 2863 [RFC2863]) section
of this document.
2.1 Relationship of this MIB Module to other MIB Modules
The relationship of the VDSL Line MIB to other MIBS and in particular
to the IF-MIB, as presented in RFC 2863 [RFC2863], is discussed in
the VDSL-LINE CORE MIB RFC XXXX [RFCXXXX]. This section outlines the
Expires January 04, 2004 [Page 2]
INTERNET-DRAFT VDSL-LINE EXTENSION MCM MIB July 2003
relationship of this VDSL Line Extension MIB to the VDSL-LINE CORE
MIB RFC XXXX [RFCXXXX].
2.2 Conventions used in the MIB Module
2.2.1 Naming Conventions
A. Vtuc -- (VTUC) transceiver at near (Central) end of line
B. Vtur -- (VTUR) transceiver at Remote end of line
C. Vtu -- One of either Vtuc or Vtur
D. Curr -- Current

I. UAS -- Unavailable Second
J. LCS -- Line Code Specific
K. Lof -- Loss of Frame

Los, Lpr, Lol)

S. Psd -- Power Spectral Density
T. Snr -- Signal to Noise Ratio

2.3 Structure
The MCM VDSL Line Extension MIB contains the following MIB group:
o vdslMCMGroup :
This group supports MIB objects for defining configuration profiles
and for montioring individual bands of Multiple Carrier Modulation
(MCM) VDSL modems. It contains the following tables:
- vdslLineMCMConfProfileTable
- vdslLineMCMConfProfileTxBandTable
- vdslLineMCMConfProfileRxBandTable
- vdslLineMCMConfProfileTxPSDTable
- vdslLineMCMConfProfileMaxTxPSDTable
- vdslLineMCMConfProfileMaxRxPSDTable
Either none, some or all of the objects in this group MAY be
implemented for MCM VDSL lines.
Figure 1, below, displays the relationship of the tables in the
vdslMCMGroup to the vdslGroup and to the ifEntry:
Expires January 04, 2004 [Page 3]
INTERNET-DRAFT VDSL-LINE EXTENSION MCM MIB July 2003
ifEntry(ifType=97) ----> vdslLineTableEntry 1:(0..1)
vdslLineTableEntry (vdslLineCoding=MCM)
vdslLineConfProfileEntry(vdslLineConfProfileName)
----> vdslLineMCMConfProfileTable 1:(0..1)
----> vdslLineMCMConfProfileTxBandTable 1:(0..1)
----> vdslLineMCMConfProfileRxBandTable 1:(0..1)
----> vdslLineMCMConfProfileTxPSDTable 1:(0..1)
----> vdslLineMCMConfProfileMaxTxPSDTable 1:(0..1)
----> vdslLineMCMConfProfileMaxRxPSDTable 1:(0..1)
Figure 1: Table Relationships
When the vdslLineCoding is set to MCM, the vdslLineConfProfileName
which is the index of the vdslLineConfProfileEntry is also used as
the index to the vdslLineMCMConfProfileTxBandTable of the
vdslMCMGroup. The existence of an entry in any of the tables of
the vdslMCMGroup is optional. Either none, some or all of the
vdslMCMGroup tables MAY be implemented for a particular VDSL line
entity using MCM line coding.
2.4 Persistence
All read-write and read-create objects defined in this MIB module
SHOULD be stored persistently. Following is an exhaustive list of
these persistent objects:
vdslMCMConfProfileTxWindowLength
vdslMCMConfProfileRowStatus
vdslMCMConfProfileTxBandNumber
vdslMCMConfProfileTxBandStart
vdslMCMConfProfileTxBandStop
vdslMCMConfProfileTxBandRowStatus
vdslMCMConfProfileRxBandStart
vdslMCMConfProfileRxBandStop
vdslMCMConfProfileRxBandRowStatus
vdslMCMConfProfileTxPSDTone
vdslMCMConfProfileTxPSDPSD
vdslMCMConfProfileTxPSDRowStatus
vdslMCMConfProfileMaxTxPSDTone
vdslMCMConfProfileMaxTxPSDPSD
vdslMCMConfProfileMaxTxPSDRowStatus
vdslMCMConfProfileMaxRxPSDTone
vdslMCMConfProfileMaxRxPSDPSD
vdslMCMConfProfileMaxRxPSDRowStatus
It SHOULD also be noted that interface indices in this MIB are
maintained persistently. VACM data relating to these SHOULD be
stored persistently as well [RFC2575].

DESCRIPTION
"The VDSL Line core MIB found in RFC XXXX defines objects for
the management of a pair of VDSL transceivers at each end of
the VDSL line. The core MIB configures and monitors the line
code independent parameters (TC layer) of the VDSL line.
This MIB module is an optional extension of the core MIB and
defines objects for configuration and monitoring of the line
code specific (LCS) elements (PMD layer) for VDSL lines using
MCM coding. The objects in this extension MIB MUST NOT be used
for VDSL lines using SCM line coding.
Naming Conventions:
Vtuc -- (VTUC) transceiver at near (Central) end of line
Vtur -- (VTUR) transceiver at Remote end of line
Vtu -- One of either Vtuc or Vtur
Curr -- Current
Prev -- Previous
Atn -- Attenuation
ES -- Errored Second.
SES -- Severely Errored Second
UAS -- Unavailable Second
LCS -- Line Code Specific
Lof -- Loss of Frame
Lol -- Loss of Link
Los -- Loss of Signal
Lpr -- Loss of Power
xxxs -- Interval of Seconds in which xxx occurs
(e.g., xxx=Lof, Los, Lpr)
Max -- Maximum
Mgn -- Margin
Min -- Minimum
Psd -- Power Spectral Density
Snr -- Signal to Noise Ratio

8. Security Considerations
There are a number of management objects defined in this MIB that
have a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.

INTERNET-DRAFT VDSL-LINE EXTENSION MCM MIB July 2003
VDSL layer connectivity from the Vtur will permit the subscriber
to manipulate both the VDSL link directly and the VDSL 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.
For this reason, there are a number of managed objects in this MIB
that may contain sensitive information.
It is thus important to control even GET access to these objects and
possibly to even encrypt the values of these objects when sending
them over the network via SNMP. Not all versions of SNMP provide
features for such a secure environment.
Further, notifications generated by agents implementing this MIB
will contain the above threshold information.
SNMP versions prior to SNMPv3 did not include adequate security.
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/SET (read/change/create/delete) objects
which utilize the textual conventions defined in this MIB module.
It is RECOMMENDED that implementers consider the security features
as provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of a MIB module which utilizes the textual conventions
defined in this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
