Diagnostics and Managed Services for Internet Service Providers

TruVizion DOCSIS & GPON Diagnostics

TruVizion Modem Diagnostics Screen

TruVizion offers broadband operators comprehensive data on the health of their network and CPE.TruVizion's real-time and historical information along with advanced mapping capabilities helps staff from multiple disciplines do their job better and more efficiently. 

"TruVizion is a Godsend for us. We're able to identify and resolve the root issues causing service problems at the subscriber level, and that has reduced our service calls tremendously. I was doing twenty to thirty calls a week before and now it's less than ten."

- Jeff Phillips, S. Breyer Cable  

SetTop VU Set-top Box Diagnostics and TV Analytics

SetTop VU STB Diagnostics Screen Shot

ZCorum's newest product, SetTop VU, displays key metrics from compatible set-top boxes in your network, helping you identify issues that could be causing a poor experience with your video service. You can see the status of the set top box, boot time, uptime, out-of-band SNR, frequency, power levels,DVR free space and MoCA network stats.

SetTop VU also displays the history of the SNR and parental controls on each tuned channel. And, you can get access to a separate TV Analytics portal to create audience segments based on the viewing behavior of your subscribers and anonymized demographic data. This allows you to target ads and negotiate programming agreements more effectively.

SpectraVizion Downstream Spectrum Monitoring

Downstream Spectrum Capture Screen Shot

SpectraVizion uses the full band capture capabilities in the CPE to display the downstream spectrum on a PC, tablet or Smartphone. SpectraVizion automatically identifies common downstream spectrum issues like Suck-outs, Roll-off, Tilt, Standing Waves, Adjacency, Resonant Peaking and FM Noise. 

You can see which devices are experiencing downstream issues and view a current or historical capture of that spectrum, allowing you to send the right technician to the right location the first time.

Upstream Spectrum Analyzer and Monitoring

Return Path Spectrum Capture Screen Shot

Upstream Analyzer displays the return path spectrum from your CMTS in real time from any location on any device. There's no expensive upstream spectrum analyzer or headend equipment to buy, and no cabling, splitters or connectors needed. All you need is your CMTS.

"I saw one modem that clearly had some ingress issues. I called the customer and asked him to tighten the connector on his modem, and watched the green Min Hold line on Upstream Analyzer dropped to the noise floor."
- Doyle Nelson, Cunningham Telephone and Cable

PreEqualization Analyzer DOCSIS PNM

"We never would have found that bad fitting had it not been for PreEqualization Analyzer. It pointed us right to the problem."
