Description: Manages Nortel Magellan Passport ISDN data channel configuration for B-channel data services.

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-DataIsdnMIB?

Nortel-Magellan-Passport-DataIsdnMIB manages ISDN B-channel data signaling configuration on the Magellan Passport switch family, covering the data signaling channel components used for ISDN data call setup. It exposes RowStatus provisioning tables, free-text comment fields, and customer identifier association tables for each signaling channel component. The MIB's practical monitoring value is in exposing the operational/row status of each ISDN data channel, since confirming a channel component is active and correctly provisioned is the primary way to detect a failed or misconfigured B-channel before it affects call setup, functioning much like a service health check for the ISDN signaling stack. It follows the shared Magellan Passport component/RowStatus conventions and layers on top of ITU-T ISDN signaling concepts. It is used on Magellan Passport switches providing ISDN data access in carrier and enterprise WAN deployments. Management tools that resolve object names in this space rely on the Nortel-Magellan-Passport-DataIsdnMIB OID tree to correctly identify each ISDN data signaling table and its indexing columns.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-DataIsdnMIB. 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 WAN switch
  • ISDN access node

Monitoring Examples

An engineer polls dataSigChanRowStatusTable/dataSigChanRowStatusEntry to verify a data signaling channel component (indexed by dataSigChanIndex) is active, and reviews dataSigChanCommentText for operator notes on a suspect channel. dataSigChanCidDataTable/dataSigChanCidDataEntry with its customer identifier links the channel to a specific subscriber's ISDN service, so if a customer reports failed data calls, the operator cross-checks dataSigChanProvTable/dataSigChanProvEntry provisioning parameters against the expected configuration.

What Can Be Monitored

  • ISDN data signaling channel row status
  • channel provisioning parameters
  • customer identifier per channel
  • operator comment text
  • component storage type
