A better broadband experience for service providers.


I’m working on an outage here in Vermont where the current temp is -12 (that’s not a typo) and I just wanted to tell you how much TruVizion is helping us out in finding the problem. In weather like this your software program is invaluable to us.
George Goodrich, TransVideo
The pre-planning ZCorum did prior to migrating our subscribers obviously paid off. I can’t say what you might have done differently to have made it any smoother, which is a testimony to how well it went. We’re very happy with the level of service we and our customers receive from ZCorum, and are also big fans of the TruVizion diagnostics software, which is much better than what we had before.
Bob Young, WEHCO Video
I’m REALLY enjoying the Geo-Coding feature you guys added. I really love the software and I love the way you are continually expanding the product.
Oliver Wilson, St. Maarten Cable TV
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

Our outside plant engineer has been using Upstream Analyzer and he’s been using it to see noise in some of the upstream. I compared what he was seeing in Upstream Analyzer with the data I was actually seeing on a hardware spectrum analyzer and I was pretty impressed with how identical it was to each other.

We switched to ZCorum from another provider because of the exceptional quality of service ZCorum delivers. The technical proficiency of their call center staff, and their highly-functional software portfolio was the perfect solution for us.

Cable operators today have huge expenditures for test equipment they provide to their field technicians so they can troubleshoot subscriber RF issues. With Remote Spectrum we see the full spectrum of downstream channels passing through any compatible cable modem or set-top box. So, there is no need to be at the customer premise or to connect a meter.
Scott Helms, VP of Technology, ZCorum

Remote Downstream Analysis

Remote Spectrum uses a DOCSIS standard to collect and display the full spectrum passing through a cable modem or set-top box. You can view the spectrum like you would on a meter, but on a PC, a tablet or smartphone, and from wherever you happen to be.
