Description: Manages DMT-based ADSL network interface configuration and line statistics on Ascend DSLAMs.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) 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.

What Is ASCEND-MIBDADSLNET-MIB?

ASCEND-MIBDADSLNET-MIB is an Ascend Communications (later Lucent/Avaya) proprietary MIB covering DMT-based ADSL (Discrete Multi-Tone Asymmetric DSL) network interfaces on Ascend DSLAM (DSL Access Multiplexer) equipment. It is expected to expose configuration objects for ADSL line provisioning as well as line-level statistics typical of DSL physical-layer monitoring. Its primary monitoring value is subscriber-line performance and fault detection — operators would use it to track per-line sync status and error counters to identify degraded or failing copper loops. It conceptually parallels the IETF's standard ADSL-LINE-MIB (RFC 2662) for DMT ADSL line objects. It was deployed in telecom central-office environments on Ascend DSLAMs aggregating residential/business ADSL subscriber lines. Engineers can download the ASCEND-MIBDADSLNET-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-MIBDADSLNET-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.

Monitoring Examples

No sample_objects or module_desc text were captured for this module in the source data, so no specific object or table names can be honestly cited. Based on its name and vendor context, a realistic use would be an operator polling per-line synchronization state and error counters to identify subscriber DSL lines with poor signal quality, but this cannot be grounded in concrete object names from the available data.

What Can Be Monitored

ADSL line sync/status
line attenuation and noise margin
line error counters

mibdadslNetworkProfileEntry	1.3.6.1.4.1.529.23.7.1.1		not-accessible	A mibdadslNetworkProfile entry containing objects that maps to the parameters of mibdadslNetworkProfile profile.
INT dadslNetworkProfile_Shelf_o	1.3.6.1.4.1.529.23.7.1.1.1	INTEGER	read-only
INT dadslNetworkProfile_Slot_o	1.3.6.1.4.1.529.23.7.1.1.2	INTEGER	read-only
INT dadslNetworkProfile_Item_o	1.3.6.1.4.1.529.23.7.1.1.3	INTEGER	read-only
STR dadslNetworkProfile_Name	1.3.6.1.4.1.529.23.7.1.1.4	DisplayString	read-write	For future use. The current design does not use the name field but instead references Dmt adsl lines by the physical address; we may in the future support referencing Dmt adsl lines by name as well as by address. The name consists of a null terminated ascii string supplied by the user; it defaults to the ascii form of the Dmt adsl line physical address.
INT dadslNetworkProfile_PhysicalAddress_Shelf	1.3.6.1.4.1.529.23.7.1.1.5	INTEGER	read-write	The number of the shelf that the addressed physical device resides on.
INT dadslNetworkProfile_PhysicalAddress_Slot	1.3.6.1.4.1.529.23.7.1.1.6	INTEGER	read-write	The number of the slot that the addressed physical device resides on.
INT dadslNetworkProfile_PhysicalAddress_ItemNumber	1.3.6.1.4.1.529.23.7.1.1.7	INTEGER	read-write	A number that specifies an addressable entity within the context of shelf and slot.
INT dadslNetworkProfile_Enabled	1.3.6.1.4.1.529.23.7.1.1.8	INTEGER	read-write	TRUE if the line is enabled, otherwise FALSE.
INT dadslNetworkProfile_ProfileNumber	1.3.6.1.4.1.529.23.7.1.1.9	INTEGER	read-write	For potential backwards compatibility. The current design consists of one line profile numbered 0.
INT dadslNetworkProfile_LineConfig_TrunkGroup	1.3.6.1.4.1.529.23.7.1.1.10	INTEGER	read-write	The trunk group to which this line is assigned. 0 means this line is not part of a trunk group.
INT dadslNetworkProfile_LineConfig_NailedGroup	1.3.6.1.4.1.529.23.7.1.1.11	INTEGER	read-write	A number that identifies the set of lines that makes up a nailed group. 0 means this line is not part of a nailed group.

INT dadslNetworkProfile_LineConfig_RoutePort_SlotNumber_ShelfNumber	1.3.6.1.4.1.529.23.7.1.1.13	INTEGER	read-write	TNT is a multi shelf system. To minimise the changes required to existing code the shelf number is added to this structure as it will almost always be needed when a slot number is needed.
