What Is CXDDS-MIB?

CXDDS-MIB is an Aastra (Concord/Coral-derived carrier telephony equipment) MIB for Digital Data Service (DDS) interface modules, covering the configuration and status of DDS line circuits installed in specific equipment slots. It exposes per-slot line configuration and revision data along with trap conditions related to DDS line events, reflecting the module's role in monitoring hardware line interfaces within a telecom chassis. Its monitoring value is centered on hardware/interface status: ddsSlotRevision identifies which hardware/firmware revision of a DDS line card is installed in a given slot, and ddsSlotLineTrap signals line-level fault or state-change events on that circuit that an operator needs to act on. No module_desc text was available for this MIB beyond its name-implied purpose, so its dependency on other MIBs cannot be confirmed, though DDS-specific vendor MIBs typically stand largely on their own. It is deployed in legacy digital data service/leased-line telecom equipment where Aastra DDS interface cards provide dedicated point-to-point digital circuits. Engineers can download the CXDDS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CXDDS-MIB. 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

  • Aastra DDS (Digital Data Service) line interface module
  • telecom digital leased-line equipment

Monitoring Examples

An operator would check ddsSlotTable entries to confirm ddsSlotRevision matches the expected hardware/firmware revision for each installed DDS line card, which matters when diagnosing compatibility issues after a hardware swap. ddsSlotLineTrap would be the key object to watch for line-fault notifications, since a DDS circuit going down would generate this trap and alert the operator to a lost leased-line connection. Because sample_objects for this module are limited, the exact scope of countable performance statistics beyond slot revision and line traps cannot be confirmed.

What Can Be Monitored

  • DDS line card hardware/firmware revision
  • DDS line trap/fault events
  • per-slot line configuration
