What Is Nortel-MsCarrier-MscPassport-DisdnNI2MIB?

Nortel-MsCarrier-MscPassport-DisdnNI2MIB defines SNMP objects for National ISDN-2 (NI2) signaling channel management on Nortel MsCarrier MscPassport switches, covering the North American ISDN D-channel signaling variant used to set up and tear down calls. It exposes row status/provisioning tables for each NI2 signaling channel, a Layer-2 (Q.921) table with protocol timers T200, T23, and N200, and a framer sub-component reflecting physical-layer synchronization. This lets an operator monitor whether an NI2 signaling channel is provisioned and active, verify its Layer-2 timer configuration, and check framer synchronization state -- together indicating the health of the ISDN signaling protocol stack and the underlying physical line hardware. It depends on the National ISDN-2 (Bellcore/Telcordia) signaling standard for its semantics, in addition to the Passport RowStatus/StorageType conventions. It is used on Nortel MsCarrier MscPassport switches providing NI2 ISDN access/trunk signaling in North American carrier networks, where operators can download the Nortel-MsCarrier-MscPassport-DisdnNI2MIB file for use in their SNMP management systems.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-DisdnNI2MIB. 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.

Nortel MsCarrier MscPassport switch (NI2 ISDN signaling)

Monitoring Examples

An operator polls mscDataSigChanNi2RowStatusTable to confirm an NI2 signaling channel is active, then checks mscDataSigChanNi2L2Table's mscDataSigChanNi2T200, mscDataSigChanNi2T23, and mscDataSigChanNi2N200 values to verify Layer-2 retransmission and timer settings. Frequent T200 expirations approaching the N200 retry limit would indicate an unstable D-channel link. The mscDataSigChanNi2Framer sub-component confirms whether the underlying physical line is correctly framed and synchronized.

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.
