What Is Nortel-Magellan-Passport-VnetEtsiQsigMIB?

This MIB is a Nortel-specific module for the Magellan Passport multiservice switching platform, defining SNMP management objects for the ETSI QSIG virtual network signaling protocol used on private branch exchange (PBX) trunk interfaces. It exposes configuration and provisioning data for signaling channels, including row-status-controlled component tables, storage type, and Layer 2 data-link parameters such as the T200, T23 and N200 timers that govern QSIG/Q.921 link establishment and retransmission behavior. Because the objects are almost entirely provisioning/configuration in nature (row status, component names, timer values) rather than live performance counters, monitoring value here centers on verifying that a signaling channel's administrative and link-layer configuration is correctly provisioned and stable (row status active/notInService) rather than tracking hardware health metrics like temperature or CPU. It builds on Nortel's proprietary Passport component-instance model (component name/index/row-status pattern used across all MsCarrier/Magellan Passport MIBs) and implicitly depends on the ITU-T Q.921/QSIG signaling stack conventions. It is typically deployed in carrier or enterprise voice networks using Nortel Magellan Passport switches to interconnect PBXs over ETSI QSIG trunks for private numbering plan and supplementary-service signaling. Engineers can download the Nortel-Magellan-Passport-VnetEtsiQsigMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-VnetEtsiQsigMIB. 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

  • Nortel Magellan Passport switch
  • PBX/voice trunk signaling interface

Monitoring Examples

An administrator would poll sigChanEQsigRowStatusTable/sigChanEQsigRowStatusEntry to confirm a QSIG signaling channel component is in the "active" row status, and inspect sigChanEQsigL2Table entries for the configured sigChanEQsigT200, sigChanEQsigT23 and sigChanEQsigN200 timer values against the far-end PBX's QSIG configuration. A mismatch or unexpected change in sigChanEQsigStorageType or component index could indicate a misconfigured or newly provisioned channel that is failing to establish Layer 2 link with the peer switch. Because this MIB has no runtime performance counters, anomalies show up as row-status transitions rather than counter thresholds.

What Can Be Monitored

  • QSIG signaling channel row status
  • Layer 2 link timers (T200, T23, N200)
  • component storage type
  • signaling channel provisioning index
