What Is Nortel-Magellan-Passport-TdmaIwfMIB?

Nortel-Magellan-Passport-TdmaIwfMIB is a Nortel Networks MIB for the Magellan Passport wide-area switching platform, providing SNMP-managed objects for configuring and monitoring the TDMA (Time Division Multiple Access) Interworking Function used to interconnect TDMA mobile carrier signaling with the Passport's packet/cell switching fabric. It exposes row-status-controlled configuration tables for TDMA connection service (CS) components, including component naming, storage type, service-provisioning parameters, and TDMA-specific timers (such as T303) used in call/connection setup. Its monitoring value lies in connection/service provisioning status: the row status objects reveal whether a TDMA interworking connection or service-provider entry is active, being created, or has failed to provision, which is central to diagnosing mobile-carrier interconnection problems on the Passport platform. As a component MIB within the broader Magellan Passport architecture, it relies on the platform's shared component-naming and row-status conventions used across other Passport MIBs. It is typically deployed on Nortel Magellan Passport wide-area switches used by mobile carriers for TDMA-based interworking in legacy cellular backhaul networks. Engineers can download the Nortel-Magellan-Passport-TdmaIwfMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-TdmaIwfMIB. 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 wide-area switching platform (mobile carrier TDMA interworking)

Monitoring Examples

An operator would poll tdmaCsRowStatusTable/tdmaCsRowStatusEntry to check tdmaCsRowStatus and tdmaCsComponentName for each TDMA CS component, confirming entries are active rather than stuck in notReady. Checking tdmaCsServProvTable/tdmaCsServProvEntry values like tdmaCsTIwf1, tdmaCsTIwf2, and tdmaCsT303 would reveal misconfigured interworking timers, which could explain repeated call setup failures or timeouts on the TDMA interworking link.

What Can Be Monitored

  • TDMA CS component row status
  • component naming and storage type
  • interworking timer configuration (e.g., T303)
  • service provider table entries
