What Is OMNI-gx2Dm200-MIB?

OMNI-gx2Dm200-MIB is a vendor-specific SNMP module written for General Instrument Corporation's OmniStar GX2 hybrid fiber-coax (HFC) headend platform, specifically the OMNISTAR DM 1550 laser module return-path transmitter (device family gx2Dm200). It extends the shared hfcCommonTable with device-specific data organized into four tables -- gx2Dm200AnalogTable, gx2Dm200DigitalTable, gx2Dm200StatusTable, and gx2Dm200FactoryTable -- exposing analog readings such as dm200currentValueLaserPower, dm200currentValueLaserTemp, dm200currentValueTecCurrent, and dm200currentValueOffsetNomMonitor, each paired with high/low alarm thresholds and a dm200alarmState indicator. It also models digital status points (dm200valueRfInput, dm200valueOptOutput, dm200valueSbsControl) and factory/diagnostic counters (dm200bank1CRC, dm200hourMeter, dm200flashPrgCntA). It depends on GX2HFC-MIB for the parent gx2Dm200 object identifier and on NLSBBN-TRAPS-MIB for shared trap variable bindings, and is deployed alongside the broader OmniStar HFC network element MIB suite used by cable headend management systems; administrators can download the OMNI-gx2Dm200-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OMNI-gx2Dm200-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 platform
  • OMNISTAR DM 1550 return-path laser transmitter module

Monitoring Examples

An operator polls dm200currentValueLaserTemp and dm200alarmStateLaserTemp on the return-path transmitter to check the laser diode's operating temperature, and a shift into majorHighAlarm or majorLowAlarm state (rather than noAlarm) would indicate the laser module is overheating or under-driven and at risk of signal degradation or failure.

What Can Be Monitored

  • Laser power, temperature, and TEC current analog levels with alarm thresholds
  • RF input and optical output digital status
  • Standby/SBS control state
  • Factory CRC and flash/boot diagnostic counters
  • Offset/nominal monitor and attenuation setting alarms
