Description: Manages DSX T1/E1 digital transmission interface configuration, framing, and performance statistics.

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 DSX-TE1-MIB?

DSX-TE1-MIB is a vendor-specific interface MIB covering DSX-panel T1/E1 digital transmission interface modules, providing configuration and performance data for these WAN circuit interfaces. It exposes line configuration data (framing, line coding, line build-out, cable length, clocking source) along with alarm conditions such as RAI (Remote Alarm Indication) and dedicated trap notifications for T1/E1 line events. Its monitoring value is squarely in circuit fault and performance monitoring: administrators track alarm state objects and performance statistics to detect line degradation, framing errors, or loss-of-signal conditions on T1/E1 circuits, which is critical for WAN service assurance. It complements and likely coexists with the standard DS1/E1 MIB (RFC 3895/2495) for baseline T1/E1 performance counters while adding vendor-specific line configuration objects. It is typically deployed on carrier or enterprise WAN edge equipment terminating T1/E1 leased lines or trunks. Network engineers evaluating or troubleshooting this functionality can download the DSX-TE1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DSX-TE1-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

  • T1/E1 DSX interface modules/panels

Monitoring Examples

Sample objects include nndsxT1E1IfConfigLineTable/Entry with fields like nndsxT1E1IfConfigLineMode, nndsxT1E1IfConfigLineType, nndsxT1E1IfConfigLineCode, nndsxT1E1IfConfigLBO, nndsxT1E1IfConfigCableLength, nndsxT1E1IfConfigRaiAlarm, and nndsxT1E1IfConfigTransmitClock, plus nndsxT1E1Traps/nndsxT1E1TrapVariables for notifications. An administrator would poll nndsxT1E1IfConfigRaiAlarm per line to detect an active Remote Alarm Indication signaling a problem at the far end, and would check nndsxT1E1IfConfigTransmitClock to confirm correct clock source selection. A trap fired from nndsxT1E1Notifications carrying an active RAI alarm would reveal a T1/E1 circuit fault requiring carrier escalation.

What Can Be Monitored

  • line framing and coding configuration
  • line build-out and cable length settings
  • transmit clock source
  • RAI alarm status
  • T1/E1 line fault trap notifications
