What Is CDD-564?

CDD-564 is a Comtech EF Data vendor-specific MIB that manages and monitors the CDD-564 satellite demodulator, exposing configuration for demodulator behavior alongside live signal-quality telemetry. Its cdd564RxTable (indexed 1..4 per demodulator) carries cdd564RxFEC (uncoded/turbo), cdd564RxDemodulation (QPSK/8-PSK/16-QAM), cdd564RxSymbolRate, cdd564RxCodeRate, and alarm thresholds like cdd564RxEbNoAlarmPoint, while runtime status objects such as cdd564RxEbNo, cdd564AGCAlarmMask, and cdd564EbNoAlarmMask report actual signal-to-noise and automatic-gain-control conditions. Event history is tracked in a per-demodulator cdd564EventTable (indexed by cdd564EventDemod and cdd564EventIndex) and long-run signal statistics in cdd564StatisticTable (cdd564StatisticAvgEbNo, cdd564StatisticMinEbNo), while cdd564AccessListTable, cdd564RouteTable, and cdd564IGMPTable manage IP-over-satellite networking features. It depends on the ComtechEFData enterprise MIB tree for its OID placement and is deployed on Comtech EF Data CDD-564 satellite modem/demodulator units in VSAT and satellite backhaul links, where technicians can download the CDD-564 MIB to load into their MIB browser for provisioning and signal-quality monitoring.

IPNetwork Monitor allows you to monitor SNMP objects defined in CDD-564. 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

  • Comtech EF Data CDD-564 satellite modem/demodulator

Monitoring Examples

An operator polls cdd564RxEbNo against cdd564RxEbNoAlarmPoint for a given cdd564RxTableIndex to check demodulator signal margin, and reviews cdd564StatisticMinEbNo to see the worst Eb/No recorded over the period; an Eb/No value dropping below the configured alarm point combined with entries appearing in cdd564EventTable would indicate a degrading satellite link or antenna pointing issue.

What Can Be Monitored

  • demodulator Eb/No signal level and alarm threshold
  • AGC and Eb/No alarm masks
  • FEC/demodulation mode and symbol rate configuration
  • per-demodulator event log table
  • long-term Eb/No statistics (avg/min)
  • IP routing and IGMP table state
