PNM - Optimize Quality of Experience by Smart Maintenance!
- Identify and locate the source of linear distortions in the field using your existing cable modem termination system (CMTS) and cable modems
- Monitor transmission impairments like micro-reflections and group delays
- Proactively identify impairments by data retrival from cable modems
- Check downstream/upstream frequency response
- Identify trends and fix network impairments before the subscriber’s service is affected
- Check spectrum changes in downstream/upstream channel in real time
