What Is Nortel-Magellan-Passport-DisdnJapanInsMIB?

Nortel-Magellan-Passport-DisdnJapanInsMIB is a Nortel proprietary MIB for the Magellan Passport WAN switching platform, specifically managing the Japanese ISDN INS-Net variant of D-channel signaling. It exposes configuration and status objects for the data signaling channel, including row-status control tables, Layer 2 framer parameters, and protocol timers (T200, T23) and retry counters (N200) governing the signaling link. Its monitoring value lies in software/protocol status: confirming whether a signaling channel's row status is active, checking the framer state, and verifying that Layer 2 timer/retry parameters match the expected INS-Net configuration to catch link instability. It depends on Nortel's broader Magellan Passport ISDN signaling channel MIB framework, of which this is the Japan INS-Net-specific extension. It is deployed on Nortel Magellan Passport multiservice WAN switches providing ISDN access in Japan-market telecom networks. Engineers can download the Nortel-Magellan-Passport-DisdnJapanInsMIB file directly to load it into their MIB browser.

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

Monitoring Examples

An operator would check dataSigChanInsRowStatus in the dataSigChanInsRowStatusTable to confirm a given INS-Net signaling channel is active, and inspect dataSigChanInsL2Table entries such as dataSigChanInsT200 and dataSigChanInsN200 to verify the Layer 2 timer and retransmission counts are within expected bounds. A channel repeatedly hitting its N200 retry limit or showing an unexpected dataSigChanInsFramer state would indicate a physical or signaling-level ISDN link problem needing investigation.

What Can Be Monitored

  • signaling channel row status
  • Layer 2 framer state
  • T200/T23 protocol timers
  • N200 retry count
  • channel storage type/index
