Description: Manages Asymmetric DSL (ADSL) line interfaces conforming to ANSI T1E1.413 and ITU-T G.992.1/G.992.2, including line configuration, status, and performance data.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring ADSL-LINE-MIB with a free 30-day trial of IPNetwork Monitor.

What Is ADSL-LINE-MIB?

ADSL-LINE-MIB is a vendor-neutral IETF standards MIB (RFC 2662) defining objects to manage a pair of ADSL modems—the ATU-C (central office side) and ATU-R (remote/customer side)—on a single DSL line, conforming to ANSI T1E1.413 and ITU-T G.992.1/G.992.2; as a ratified IETF standard, the ADSL-LINE-MIB MIB is implemented consistently across DSLAM and CPE vendors alike. It exposes line configuration and physical-layer performance data including line rates, noise margins, attenuation, and per-channel (fast/interleaved) statistics, as well as trap definitions for line-state changes. Its monitoring value is centered on physical-layer/hardware status of the DSL link itself—line up/down transitions, signal quality degradation, and channel-level performance—rather than general device CPU or memory health, and the adslAtucTraps/adslAturTraps notify on faults at each end of the line. It builds on the standard SNMPv2 framework and is commonly paired with the ifTable (IF-MIB) since each ADSL line appears as an interface. It is typically deployed by telecom/ISP operators and DSLAM or CPE vendors to remotely monitor last-mile broadband line quality and modem health.

IPNetwork Monitor allows you to monitor SNMP objects defined in ADSL-LINE-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
ADSL modems/DSLAMs and ADSL customer-premises equipment (CPE)

Monitoring Examples

An operator would poll the adslMibObjects subtree to check per-line signal margin and attenuation values that indicate marginal copper-loop quality, and watch for adslAtucTraps/adslAturTraps notifications signaling loss of signal or frame synchronization at either the central-office or customer-premises modem. Because ADSL lines can carry optional Fast or Interleaved channels, additional performance table entries corresponding to those channels would be checked to isolate whether errors are occurring in a specific channel type. A sudden drop reflected in the adslConformance-referenced line-rate objects would flag a degrading or failing DSL connection needing a truck roll.

What Can Be Monitored

ADSL line rate
signal-to-noise margin
line attenuation
fast/interleaved channel performance
line up/down trap events
ATU-C/ATU-R modem status

How to Use in IPNetwork Monitor

Example using adslAtucCurrSnrMgn OID:

Select an ADSL DSLAM or CPE modem as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type adslAtucCurrSnrMgn into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the noise margin on this ADSL line's received signal, in tenths of a dB, as seen by the ATU-C. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value drops below 60 (i.e. 6.0 dB), since low noise margin often precedes line errors or a lost DSL sync. Click Finish to create the monitor; you can adjust any parameter later.

adslMIB	1.3.6.1.2.1.10.94			The MIB module defining objects for the management of a pair of ADSL modems at each end of the ADSL line. Each such line has an entry in an ifTable which may include multiple modem lines. An agent may reside at either end of the ADSL line however the MIB is designed to require no management communication between them beyond that inherent in the low-level ADSL line protocol. The agent may monitor and control this protocol for its needs. ADSL lines may support optional Fast or Interleaved channels. If these are supported, additional entries corresponding to the supported channels must be created in the ifTable. Thus an ADSL line that supports both channels will have three entries in the ifTable, one for each physical, fast, and interleaved, whose ifType values are equal to adsl(94), fast(125), and interleaved(124), respectively. The ifStackTable is used to represent the relationship between the entries.

FAQ

What would an ISP check via ADSL-LINE-MIB to monitor last-mile DSL line quality?
They'd poll physical-layer performance data such as line rate, signal-to-noise margin, and line attenuation, plus per-channel (fast/interleaved) statistics, to detect signal quality degradation on individual ADSL lines before it causes a customer-visible outage.

How does ADSL-LINE-MIB notify an operator of a line going down?
It defines trap definitions for line-state changes -- the adslAtucTraps and adslAturTraps -- which notify on faults at each end of the line (central-office ATU-C and customer-premises ATU-R), letting monitoring systems react to line up/down transitions in near real time.

RFC description
