What Is DSX-TE3-MIB?

DSX-TE3-MIB is a vendor-specific interface MIB covering DSX-level T3/E3 digital transmission interface modules, defining configuration for line type, line coding, cable length, and transmit clock source, along with DS3-specific scrambling and bandwidth/timeslot options (shown commented out in the source, suggesting optional or deprecated features). It focuses on physical-layer transmission configuration for high-speed T3 (DS3, 44.736 Mbps) and E3 circuits, plus a Traps/Notifications branch for line-level fault events. Its monitoring value is centered on hardware and physical-layer status of T3/E3 circuits: administrators verify line type/line code configuration matches the far end, monitor cable length settings for signal integrity, and rely on the trap variables to be alerted to line alarms (e.g., loss of signal, alarm indication signal) as they occur on the interface. As a DSX-level interface MIB it commonly complements or overlaps with the standard DS3/E3 MIB (RFC 3896) for the base performance counters, while adding this vendor's own configuration objects. It is deployed on network equipment providing T3/E3 digital transmission interfaces, typically in carrier or enterprise WAN aggregation contexts. Engineers can download the DSX-TE3-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DSX-TE3-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

  • T3/E3 (DS3) digital transmission interface module/device

Monitoring Examples

An administrator would check nndsxT3E3IfConfigLineTable / nndsxT3E3IfConfigLineEntry (indexed by nndsxT3E3IfIndex) for nndsxT3E3IfConfigLineType, nndsxT3E3IfConfigLineCode, and nndsxT3E3IfConfigCableLength to confirm the T3/E3 line is configured to match the far-end equipment and cable run length. nndsxT3E3IfConfigTransmitClock would be checked to verify the clock source (e.g., internal vs. line-derived) is correctly set, since a clocking mismatch commonly causes frame slips. The nndsxT3E3Traps / nndsxT3E3TrapVariables branch would be configured on the NMS to receive immediate notification of a T3/E3 line alarm such as loss of signal.

What Can Be Monitored

  • T3/E3 line type and line coding configuration
  • cable length setting
  • transmit clock source
  • T3/E3 line alarm/trap events
