Description: MIB for managing QAM RF channel parameters, symbol rates, and output configuration on ARRIS D5 Universal Edge QAM (UEQ) devices

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ARRIS-D5-QAM-MIB?

This is an ARRIS enterprise MIB for managing QAM (Quadrature Amplitude Modulation) RF output channels on the D5 Universal Edge QAM (UEQ) platform, used to deliver digital video and DOCSIS signals over cable RF plant. It exposes configuration for QAM channel parameters such as RF frequency, symbol rate, modulation profile, and output port assignment for each QAM channel on the device. Its monitoring role centers on the operational/software status of each QAM channel, confirming a channel is provisioned and actively modulating at the correct frequency and symbol rate, which is essential for delivering error-free digital services to subscribers. It works alongside the ARRIS-D5-DVB-PSIG-MIB and standard cable MIBs to provide a full picture of edge-QAM output health. It's typically deployed on ARRIS D5 UEQ devices in cable operator headends generating RF QAM channels for video and DOCSIS downstream delivery. Engineers can download the ARRIS-D5-QAM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ARRIS-D5-QAM-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.

Monitoring Examples

A headend engineer would poll each QAM channel's configured RF frequency and symbol rate to confirm it matches the channel plan, and check output port assignment to ensure the channel is mapped to the correct combiner/RF output. A channel showing a mismatched symbol rate or an unexpectedly disabled output state would explain subscriber-reported pixelation or loss of a specific channel. No sample object names were available for this module to cite directly.

What Can Be Monitored

QAM RF channel frequency
symbol rate configuration
output port assignment
channel modulation profile
QAM channel operational status
