What Is Nortel-MsCarrier-MscPassport-BitTransparentMIB?

Nortel-MsCarrier-MscPassport-BitTransparentMIB is part of Nortel's MsCarrier/MscPassport WAN switch MIB family, defining objects for provisioning "bit-transparent" circuit-emulation service interfaces -- data services that transparently carry a fixed-rate bit stream (e.g. leased-line emulation) across the Passport switch fabric. It exposes row-status-managed provisioning tables for creating/deleting bit-transparent service components, customer identifier association, and per-interface entry tables linking the service to underlying framer resources. This is primarily a service-provisioning/configuration MIB; its monitoring value lies in confirming a bit-transparent circuit's mscBtdsRowStatus is active and correctly associated with the correct customer and framer interface, which is essentially a software/service-status check rather than an environmental one. It is one module within Nortel's large MsCarrier/MscPassport MIB suite and depends on shared row-status/storage-type conventions (RFC 1903-style RowStatus) common across that family. Typical deployment is on Nortel Passport multiservice WAN switches used by carriers to provision leased-line/circuit-emulation services for customers. Engineers can download the Nortel-MsCarrier-MscPassport-BitTransparentMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-BitTransparentMIB. 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 Passport (MsCarrier/MscPassport) multiservice WAN switches

Monitoring Examples

An operator would check mscBtdsRowStatusTable (mscBtdsRowStatusEntry) to confirm a given mscBtdsComponentName's mscBtdsRowStatus is active, then cross-reference mscBtdsCidDataTable for the associated mscBtdsCustomerIdentifier to verify the circuit is provisioned for the correct customer. The mscBtdsIfEntryTable ties the bit-transparent service to its underlying framer interface via mscBtdsFramer, so a service stuck in a notReady row status alongside a missing framer association would indicate a provisioning or hardware-mapping problem preventing the circuit from carrying traffic.

What Can Be Monitored

  • bit-transparent service row status
  • customer identifier association
  • framer interface mapping
  • service component storage type
