What should be checked on digital television channels if a customer is adding high-speed data service?

When a customer is adding high-speed data service, it is important to check for intermittent operation for possible interference. The reason for this is that the addition of high-speed data can increase the demand on bandwidth and may lead to potential interference with digital television channels. Intermittent issues can manifest as pixelation, loss of audio, or complete channel dropouts, which are indicative of signal quality problems.

Digital television services rely on strong and stable signal integrity, so any fluctuating performance can suggest issues that need to be addressed, such as electromagnetic interference or inadequate cable quality.

While other factors like color quality, the number of channels available, and signal strength can impact the viewing experience, they do not directly relate to the operational stability of the digital channels when a high-speed data service is added. Interference issues can significantly degrade the performance of both television and data services, making it crucial to identify and mitigate any possible sources of intermittent operation.
