What Is Nortel-MsCarrier-MscPassport-DisdnJapanInsMIB?

Nortel-MsCarrier-MscPassport-DisdnJapanInsMIB is a Nortel MsCarrier MscPassport enterprise MIB modeling the Japan INS-variant of Digital ISDN signalling on the MscPassport carrier switching platform, specifically the mscDataSigChanIns component that governs a D-channel signalling link's connection to external PBX equipment. mscDataSigChanInsRowStatusTable and mscDataSigChanInsL2Table expose provisionable Q.931/layer-2 parameters (T23/T200/T203 timers, N200/N201 retry and octet limits, CircuitSwitchedK B-channel frame limit) and mscDataSigChanInsProvTable sets the network/user side of the link; operational state is exposed via mscDataSigChanInsOperTable (active/peak active channel counts, mscDataSigChanInsDChanStatus covering outOfService/establishing/established/enabling/inService/restarting) and the nested Framer sub-component's mscDataSigChanInsFramerStateTable (OSI admin/operational/usage state) and mscDataSigChanInsFramerStatsTable (frame counts, CRC/LRC/non-octet errors, overruns/underruns, oversized-frame errors). This gives a carrier operator deep visibility into whether a D-channel is up, how many channels it is carrying, and whether the underlying hardware framer is experiencing datapath errors — critical for diagnosing PBX connectivity or signalling failures. It depends on the broader MscPassport component-model MIBs (UsefulDefinitions, StandardTextualConventions, TextualConventions, DataIsdnMIB), and is deployed on Nortel MscPassport carrier switches serving Japan INS ISDN trunks; carriers can perform a Nortel-MsCarrier-MscPassport-DisdnJapanInsMIB download for their legacy Passport network management systems.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-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.

Monitoring Examples

An operator polls mscDataSigChanInsDChanStatus for a given signalling channel and checks mscDataSigChanInsFramerStatsTable's mscDataSigChanInsFramerCrcErrors and overrun/underrun counters; a status stuck in establishing alongside climbing CRC errors would indicate a failing D-channel link to the PBX rather than a normal restart.

What Can Be Monitored

D-channel signalling status (out-of-service/establishing/established/in-service)
active and peak active channel counts
layer-2 Q.931 timer/retry configuration
framer OSI admin/operational/usage state
framer frame count and CRC/LRC/overrun/underrun error counters

OCT mscDataSigChanInsTracing	1.3.6.1.4.1.562.36.2.1.120.11.16.1.1	OCTET STRING	read-write	This attribute defines which types of tracing are active for this signalling channel. 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.
