Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

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 Single Carrier Modulation
   (SCM) Line Coding.  It is an optional extension to the VDSL-LINE-MIB,
   RFC 3728, which handles 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 (PMD) Layer of SCM VDSL Lines.
   These definitions are based upon the specifications for VDSL as
   defined in T1E1, European Telecommunications Standards Institute
   (ETSI), and International Telecommunication Union (ITU) documentation
   [T1E1311, T1E1011, T1E1013, ETSI2701, ETSI2702, ITU9931, ITU9971].
   Additionally the protocol-dependent (and line-code dependent)
   management framework for VDSL lines specified by the Digital
   Subscriber Line Forum (DSLF) has been taken into consideration
   [DSLFTR57] and [DSLFWT96].

   The MIB module is located in the MIB tree under MIB-2 transmission.

   The key words "MUST", "MUST NOT", "RECOMMENDED", and "SHOULD" in this
   document are to be interpreted as described in [RFC2119].

2.1.  Relationship of this MIB Module to Other MIB Modules

   The relationship of the VDSL Line MIB module to other MIB modules, in
   particular to the IF-MIB presented in RFC 2863 [RFC2863], is
   discussed in the VDSL-LINE-MIB, RFC 3728 [RFC3728].  This section
