Advanced Network Monitor allows Cable Operators to assure service availability and performance in real time. Using pre-equalization monitoring & spectrum analysis tools, the solution proactively scans network resources to prevent and correct network issues.
The spectrum analyzer allows both the NOC operator and field technicians to visualize the Cable Modem’s downstream channel and CMTS upstream channel frequency spectrum in a single view in order to compare them and check their shape against its historical maximums and minimums for further analysis. A mobile-friendly portal allows technicians in the field to have a real-time view of a specific node’s spectrum.
The pre-equalizer monitoring functionality is based on the possibility of using DOCSIS devices as probes for network monitoring. This is accomplished by scanning and storing functional values of cable modems and depending on the corrections being made by the device to fix network problems, it is possible to obtain valuable information in order to detect and correct network errors before they affect service. By combining the analysis of this information, network topology and device location, the source of the problem can easily be determined and a proactive maintenance plan can be triggered using this information.
