DOCSIS
End-of-Line RF Monitor

The CMD-EL is a strand or pedestal mounted network health test point capable of the delivering RF level measurements, digital measurements on the downstream DOCSIS channel, and VoIP metrics. The CMD-EL can provide measurement data in real time to aid in diagnosing network faults and can also provide scheduled measurements to aid in diagnosing intermittent network performance issues. The device can be programmed to monitor and alarm on specific RF characteristics and proactively notify users when RF characteristics are outside of user-defined parameters.
