A few weeks after introducing the service in California and Nevada, AT&T has begun offering its 45 Mbps broadband tier, called U-verse Power, in 40 additional markets across 15 states in the Northeast, North Central and Southeast  regions of the U.S.

U-verse Power is available to eligible residential customers at introductory rates as low as $49.95 a month for up to 24 months when bundled with qualifying TV and voice services. At the end of the promotional period, prices will rise above $70 a month. Business pricing varies.

Eligibility will be determined by whether or not subscribers reside on DSL loops short enough to sustain rates up to 45 Mbps downstream (and 6 Mbps up). In California and Nevada markets, only about half of all U-verse customers initially qualified.

AT&T said it plans to expand to more markets on an ongoing basis. The company also reiterated its intention to eventually offer a 100 Mbps tier. The company achieves 45 Mbps rates through channel bonding. It remains to be seen how it expects to achieve 100 Mbps, though it acknowledged that it is testing vectored DSL technology.
