What Is Unisphere-Data-DS3-MIB?
Unisphere-Data-DS3-MIB is a vendor-specific enterprise MIB from Unisphere Networks (whose ERX broadband edge router line was later acquired by Juniper Networks) for managing DS3/T3 WAN interfaces. It exposes configuration data such as line length, line type, framing/cell-scrambler settings, channelization mode, and DSU application mode for each DS3 port, along with row-status controls for provisioning. Network operators use it to monitor the hardware status of physical T3 circuits, confirming that a line is correctly configured, tracking interface indexes bound to logical channels, and detecting misconfiguration or framing mismatches that would otherwise cause link-down conditions. It builds on the same conceptual model as the standard DS3/E3 interface MIBs (e.g., RFC 2496) but adds Unisphere-specific extensions like cell scrambling for ATM-over-DS3 and channelized DS3 support. It is typically deployed on ERX-series broadband service routers at ISP points of presence where T3 trunks aggregate downstream DSL or cable traffic. Engineers can download the Unisphere-Data-DS3-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in Unisphere-Data-DS3-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.
What Can Be Monitored
- DS3 line type and length
- cell scrambler configuration
- channelization mode
- DSU application mode
- interface row/provisioning status
Supported Devices
- Unisphere/Juniper ERX broadband edge router
- DS3/T3 WAN interface card
Monitoring Examples
An operator would poll usdDsx3ConfigTable/usdDsx3ConfigEntry per usdDsx3LowerIfIndex to verify usdDsx3LineType and usdDsx3LineLength match the provisioned circuit, and check usdDsx3CellScramblerConfig to confirm ATM cell scrambling is enabled as expected. Unexpected changes to usdDsx3Channelization or usdDsx3Ds3DsuMode would reveal a misprovisioned interface causing bit errors or loss of framing. usdDsx3RowStatus can be watched during provisioning to confirm a row transitioned cleanly to active.
