Description: Manages Nortel Magellan Passport ISDN NIS Canadian national signaling protocol configuration.

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-DisdnNISMIB?

This is a Nortel Magellan Passport MIB module managing the Canadian National ISDN Supplement (NIS) signaling protocol configuration on Passport wide-area switching platforms. It exposes configuration and status data for ISDN data signaling channels, including row-status provisioning tables, Layer 2 (LAPD) framer parameters, and signaling timers/counters such as T200, T23, and N200 retransmission settings. As a signaling-layer management MIB it is used mainly to monitor and configure protocol state — row status of signaling channel entries and Layer 2 framer configuration — rather than physical sensors, though anomalies in these parameters directly reflect ISDN link health. It is part of the broader Nortel Magellan Passport enterprise MIB family and depends on Passport's proprietary component-naming and row-status conventions shared across its other signaling MIBs. It is deployed on legacy Nortel Magellan Passport WAN switches carrying Canadian NIS ISDN signaling channels. Engineers can download the Nortel-Magellan-Passport-DisdnNISMIB file directly to load it into their MIB browser.

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

Monitoring Examples

An administrator would poll dataSigChanNisRowStatusTable/dataSigChanNisRowStatusEntry (indexed by dataSigChanNisIndex) to confirm a given signaling channel's dataSigChanNisRowStatus is active rather than stuck in a notReady state. The dataSigChanNisL2Table exposes Layer 2 timer objects such as dataSigChanNisT23 and dataSigChanNisT200; an unexpectedly high count of T200 retransmission timeouts would indicate an unstable or noisy ISDN signaling link.

What Can Be Monitored

signaling channel row status
Layer 2 (LAPD) framer configuration
T200/T23 timer values
N200 retransmission count

The tracing messages are sent to the debug stream. To see the messages the agentQueue attribute in Col/debug must be greater than 0 and a Telnet NMIS session must list the debug stream in in its data streams (ex. set nmis telnet session/1 dataStreams debug). Different types of tracing can be enabled simultaneously. Note that tracing consumes additional CPU resources and will slow down call processing on a heavily loaded card. If there is message block exhaustion tracing will be suspended for a period and then automatically reenabled. An alarm is generated on tracing suspension and resumption. This mechanism protects the function processor against excessive numbers of tracing messages. Types of tracing include: protocolErrors - get details of any protocol errors which are occuring. Protocol errors are also reported in summary form as alarms. q931Summary - Summary of the Q.931 messages on the signalling link, including certain call details (calling number, called number, release codes). q931Hex - Q.931 messages displayed in hex format. Useful to determine protocol compliance in case of errors reported on local or remote ends. q931Symbolic - Q.931 messages parsed to give maximum detail. Useful for understanding content of messages flowing on the link. portHex - Messages in hex format being sent and received on the link.
