Charter Communications is reminding customers to obtain their new digital cable boxes before the company switches to an all-digital signal next week.

The company says customers will have access to more channels with better picture quality, on-demand video and faster Internet speeds as a result of the changeover.

More than 90 percent of customers in Virginia and North Carolina already have the digital box for at least one television in their home, according to a company press release.

Customers can receive one or more digital boxes at no cost for one, two or five years, depending on the customer’s programming package and other qualifying factors. Customers can obtain these digital boxes through direct shipment to their home by calling 1-888-438-2427 to request a self-installation kit, or pick up equipment at a nearby Charter Store.

Charter Store locations in the area include at 216 Moore Ave. in Suffolk and 200 Main St. in Franklin.

Charter is communicating with customers about their scheduled upgrade date via direct mail, bill messages, outbound calls, and messages that will appear on their television set prior to the cutover.

Charter has already completed all-digital upgrades in several markets, including parts of Michigan, Missouri, Texas, California, South Carolina and Massachusetts. The company plans to complete the upgrade across its 29-state footprint by the end of 2014.

Charter says it already has “a significant fiber optic network in place in Suffolk” to support the digital changeover.

“By removing outdated analog signals, we regain bandwidth in our network enabling us to provide more HD (high-definition) channels and open the door to faster Internet speeds and future innovations,” the company’s president and CEO, Tom Rutledge, said in a news release.

It’s been made possible with a $2-billion investment, he added.
