What Is OMNI-gx2Dm1000-MIB?

This is a vendor-specific MIB, associated with Cisco/Scientific Atlanta OMNI-branded HFC (hybrid fiber-coax) headend equipment, covering the GX2 Dm1000 downstream optical transmitter module used in cable television plant headends to convert electrical RF signals to optical signals for fiber transport. It would expose configuration and status objects for the optical transmitter module, such as optical output power and operating mode, though no sample objects were provided to confirm exact object names. Its expected monitoring role is hardware status of the optical transmission path: operators would use it to track optical output level, module operational/alarm status, and possibly temperature, since a degraded or failed optical transmitter directly affects downstream signal quality for all subscribers on that fiber segment. No specific dependency on other MIBs can be confirmed from the available data, though it likely fits within a broader Scientific Atlanta/Cisco headend equipment MIB hierarchy. It is deployed in cable operator headends and hub sites as part of the HFC plant's fiber-optic downstream transmission equipment. Network engineers evaluating or troubleshooting this functionality can download the OMNI-gx2Dm1000-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OMNI-gx2Dm1000-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

  • General Instrument OmniStar GX2 HFC headend/optical node (GX2 Dm1000 downstream optical transmitter module)

Monitoring Examples

No sample objects were provided for this MIB, so specific object names cannot be cited; a realistic scenario would involve polling the module's optical output power and alarm/status objects to detect a transmitter degrading below its rated output level, which would manifest as poor picture/data quality for subscribers downstream on that fiber node, but this cannot be grounded in confirmed object names from the source data.

What Can Be Monitored

  • optical output power
  • module operational/alarm status
