America’s leading cable company, Comcast, is entering the small- to medium-sized business telecom market for the first time, putting additional pressure on industry incumbents like AT&T.

Comcast’s Business Class Voice service, which can be bundled with high-speed internet and IPTV for as little as $100/month, was launched yesterday in a number of New England states.

These business owners now have the option of choosing Comcast for all of their communications needs where they work, said Jeff Freyer, Comcast’s regional vice president of business services in Connecticut-West.

But don’t expect big telecom operators to give up lucrative business subscribers without a fight, especially given their past investment in enterprise infrastructure.

Small businesses are becoming a sweet spot for AT&T, commented Adam Cormier, an AT&T spokesman. A lot of the products run downstream from large businesses to small businesses.

But businesses are increasingly bundling all of their services with a single provider so as to save money, and it seems to be an all out battle between cable and telecom as to who can provide the best deal.

Saving money, after all, is critical to most small businesses, and many managers won’t hesitate to switch providers when it comes to saving a few dollars a year.

For a small business to save any money even if it`s just $100 can be a big deal, explained Andrew Markowski, director of the Connecticut chapter of the National Federation of Independent Business, who isn’t surprised by Comcast’s play for the small business market, and expects more competition in the months and years to come. It`s a very interesting trend, he said.
