In a DOCSIS 3.0 (Data Over Cable Service Interface Specification) environment, the upstream bandwidth becomes crowded with wider and higher order QAM modulation carriers and channel bonding, leading to increased impairment sensitivity. In addition, the increasing ubiquity of DOCSIS cable modems actually represents one of the significant challenges for maintaining good plant health. The modems themselves can be serious interferers. In order to take a truly ‘proactive’ vs. ‘reactive’ approach in network monitoring, it is important to first detect the plant issues before it becomes significant enough to impact subscribers; then correlate the identified issue(s) to the physical location(s) of the modems contributing harm to the cable plant.
Under the VeSion system umbrella, VeEX’s CX380X advanced Spectrum Analyzer and Burst Demodulator is an add-on to existing CX180R and RealWORX 24x7 preventive network monitoring systems. Specific triggered alarms associated with Upstream parameters of subscriber’s cable modems, such as high transmit levels, can automatically engage deeper dive measurements of the Upstream signal quality. This helps identify the rogue cable modems in the network that contribute harm to the plant.
