What Is Nortel-Magellan-Passport-GsmIwfMIB?

This MIB defines the GSM Interworking Function on Nortel Magellan Passport multiservice switches, used to interwork GSM mobile-carrier circuit-switched data services with the Passport packet backbone in mobile network backhaul. It exposes gsmCsProvTable, which holds the MSC IP address (gsmCsMscIpAddress), associated virtual router name, and trunk-group indexing for circuit groups feeding the interworking function. Monitoring here emphasizes trunk group and connectivity provisioning status toward the mobile switching center, plus modem resource status (gsmCsModem) used for GSM interworking data calls - both essential to confirming the mobile backhaul path is functional. It depends on the Passport component/RowStatus conventions and interacts with underlying IP and virtual-routing MIBs referenced by gsmCsVirtualRouterName. It is deployed in mobile operator networks where Magellan Passport switches provide GSM circuit-data interworking into the packet backbone. Engineers can download the Nortel-Magellan-Passport-GsmIwfMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-GsmIwfMIB. 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 multiservice switch
  • Mobile carrier GSM interworking gateway

Monitoring Examples

An operator checks gsmCsProvTable/gsmCsProvEntry to confirm gsmCsMscIpAddress and gsmCsVirtualRouterName are correctly provisioned for a trunk group identified by gsmCsTrunkGrpIndex, and reviews gsmCsModem-related objects for available or failed interworking modem resources. gsmCsRowStatus indicates whether a circuit-switched trunk group component is active. A trunk group with gsmCsRowStatus stuck at notInService, or a configured MSC IP address that is unreachable, signals a break in GSM data interworking connectivity to the mobile switching center.

What Can Be Monitored

  • trunk group provisioning status
  • MSC IP address reachability config
  • virtual router association
  • modem resource status
  • component row status
