Description: Defines textual conventions for managing VDSL2 interfaces, also applicable to ADSL, ADSL2, and ADSL2+ management.
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring VDSL2-LINE-TC-MIB with a free 30-day trial of IPNetwork Monitor.
What Is VDSL2-LINE-TC-MIB?
VDSL2-LINE-TC-MIB is an IETF standards-track module that defines Textual Conventions (shared data types) used by the companion VDSL2-LINE-MIB to manage VDSL2 lines, and explicitly also applicable to ADSL, ADSL2, and ADSL2+ line management. It is a pure textual-conventions module and defines no scalar or tabular data objects of its own -- its purpose is to establish consistent, reusable type definitions (such as encodings for line status, band plans, or profile parameters) that other DSL MIBs build upon. As a result it has no direct monitoring role for hardware or software status; the actual line-rate, sync-status, and error-counter monitoring happens in VDSL2-LINE-MIB, which imports these conventions. Its dependency relationship is explicit and central: it exists specifically to support VDSL2-LINE-MIB (and by extension ADSL-family MIBs) with common types. Anyone consulting the VDSL2-LINE-TC-MIB OID list will find only these shared type definitions rather than pollable data objects, confirming its supporting role. It is relevant wherever DSL access equipment -- typically DSLAMs and modems supporting VDSL2/ADSL2+ -- is managed via SNMP.
IPNetwork Monitor allows you to monitor SNMP objects defined in VDSL2-LINE-TC-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer
- DSL access equipment (DSLAMs, VDSL2/ADSL2+ modems and line cards)
Monitoring Examples
This module defines no runtime objects to poll; it is a conformance/type-support module rather than a data-carrying MIB, so it exposes no monitoring scenario on its own. Any anomaly detection for VDSL2/ADSL line rate, sync state, or noise margin would be performed against the companion VDSL2-LINE-MIB, which uses the textual conventions declared here.

RFC description
IETF textual conventions for managing VDSL2, ADSL, ADSL2, and ADSL2+ line parameters.
Start monitoring vendor-neutral, standards-based MIB, DSL access equipment (DSLAMs, VDSL2/ADSL2+ modems and line cards) (shared textual conventions, no data objects) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
