Description: Defines SNMP objects for voice networking services including routing and trunking on Nortel Magellan Passport switches.

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 Nortel-Magellan-Passport-VoiceNetworkingMIB?

This is a Nortel-specific MIB for the Magellan Passport (later MsCarrier Passport) multiservice switching platform, focused on voice networking services such as signaling channels and trunking. It exposes configuration and status data for signaling channel (sigChan) row-status tables, customer identifier data, and channel-to-interface mappings used in voice/trunk provisioning. It is used to monitor the operational and administrative status of voice signaling channels, correlating channels to physical/logical interfaces and customer accounts. Each Nortel-Magellan-Passport-VoiceNetworkingMIB OID for the sigChan tables is scoped under the vendor's Passport enterprise branch, consistent with sibling shelf and trunk MIBs. It follows Nortel's proprietary component/row-status modeling convention shared across sibling Passport MIBs (e.g., shelf, trunk MIBs) rather than standard IETF MIBs. It is deployed in legacy Nortel Passport-based carrier and enterprise voice/data multiplexing networks.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-VoiceNetworkingMIB. 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 / MsCarrier Passport multiservice switch

Monitoring Examples

Polling sigChanRowStatusTable/sigChanRowStatusEntry lets an operator check sigChanRowStatus (active/notInService/etc.) for each channel identified by sigChanIndex, revealing provisioning or channel-down conditions. sigChanCidDataTable ties a channel to its sigChanCustomerIdentifier for billing/service correlation, while sigChanIfEntryTable maps signaling channels to underlying interfaces for fault isolation when a bearer channel (sigChanBch) reports errors.

What Can Be Monitored

  • signaling channel row status
  • signaling channel storage type
  • customer identifier per channel
  • signaling channel to interface mapping
  • bearer channel status
