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.

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.

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
