Description: Manages unchannelized DS3 WAN interface configuration and statistics on Ascend equipment.

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-MIBUDS3NET-MIB?

ASCEND-MIBUDS3NET-MIB is a legacy Ascend Communications enterprise MIB intended to manage unchannelized DS3 WAN interfaces, a T3-speed leased-line interface type used in older WAN access equipment. No module description or sample objects were available in the source, but based on its name and vendor lineage it would typically expose DS3 line configuration (framing, line build-out) and physical/software status counters (line errors, alarm states, loss of signal). Administrators would use such a MIB to monitor the hardware health of the DS3 physical interface, including alarm and error conditions that indicate a degraded WAN circuit. It would likely align conceptually with the standard DS3/E3 MIB (RFC 3896/2496) though implemented as a proprietary Ascend module. It would have been deployed on Ascend WAN access/routing equipment terminating unchannelized DS3 leased lines, common in ISP and enterprise WAN access in the 1990s-2000s, and legacy documentation allows administrators to download the ASCEND-MIBUDS3NET-MIB file for reference when maintaining older equipment.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-MIBUDS3NET-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

Ascend WAN access router/multiplexer (DS3 interface)

Monitoring Examples

Given the lack of exposed sample objects, a concrete monitoring scenario cannot be grounded in specific object names for this module; documentation would need to be consulted for actual table/object names such as line configuration or alarm status entries typical of DS3 interface MIBs. In general terms, an admin would be expected to poll for DS3 line alarm state and error second counts to detect a degraded or down unchannelized DS3 circuit.

What Can Be Monitored

DS3 line alarm/status
line configuration parameters
DS3 error/performance counters

OID symbolic	OID numeric	Type	Access	Description
mibuds3NetworkProfile	1.3.6.1.4.1.529.23.5
mibuds3NetworkProfileTable	1.3.6.1.4.1.529.23.5.1		not-accessible	A list of mibuds3NetworkProfile profile entries.
mibuds3NetworkProfileEntry	1.3.6.1.4.1.529.23.5.1.1		not-accessible	A mibuds3NetworkProfile entry containing objects that maps to the parameters of mibuds3NetworkProfile profile.
INT uds3NetworkProfile_Shelf_o	1.3.6.1.4.1.529.23.5.1.1.1	INTEGER	read-only
INT uds3NetworkProfile_Slot_o	1.3.6.1.4.1.529.23.5.1.1.2	INTEGER	read-only
INT uds3NetworkProfile_Item_o	1.3.6.1.4.1.529.23.5.1.1.3	INTEGER	read-only
STR uds3NetworkProfile_Name	1.3.6.1.4.1.529.23.5.1.1.4	DisplayString	read-write	For future use. The current design does not use the name field but instead references Uds3 lines by the physical address; we may in the future support referencing Uds3 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 Uds3 line physical address.
INT uds3NetworkProfile_PhysicalAddress_Shelf	1.3.6.1.4.1.529.23.5.1.1.5	INTEGER	read-write	The number of the shelf that the addressed physical device resides on.
INT uds3NetworkProfile_PhysicalAddress_Slot	1.3.6.1.4.1.529.23.5.1.1.6	INTEGER	read-write	The number of the slot that the addressed physical device resides on.
INT uds3NetworkProfile_PhysicalAddress_ItemNumber	1.3.6.1.4.1.529.23.5.1.1.7	INTEGER	read-write	A number that specifies an addressable entity within the context of shelf and slot.
INT uds3NetworkProfile_Enabled	1.3.6.1.4.1.529.23.5.1.1.8	INTEGER	read-write	TRUE if the line is enabled, otherwise FALSE.
INT uds3NetworkProfile_ProfileNumber	1.3.6.1.4.1.529.23.5.1.1.9	INTEGER	read-write	For potential backwards compatibility. The current design consists of one line profile numbered 0.
INT uds3NetworkProfile_LineConfig_TrunkGroup	1.3.6.1.4.1.529.23.5.1.1.10	INTEGER	read-write	The trunk group to which this line is assigned. 0 means this line is not part of a trunk group.
INT uds3NetworkProfile_LineConfig_NailedGroup	1.3.6.1.4.1.529.23.5.1.1.11	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 uds3NetworkProfile_LineConfig_RoutePort_SlotNumber_SlotNumber	1.3.6.1.4.1.529.23.5.1.1.12	INTEGER	read-write
INT uds3NetworkProfile_LineConfig_RoutePort_SlotNumber_ShelfNumber	1.3.6.1.4.1.529.23.5.1.1.13	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.
INT uds3NetworkProfile_LineConfig_RoutePort_RelativePortNumber_RelativePortNumber	1.3.6.1.4.1.529.23.5.1.1.14	INTEGER	read-write
