AT&T finally completed its $86 billion acquisition of BellSouth after receiving long-delayed FCC approval in late December. But the deal didn’t get the final nod without a lot of concessions from AT&T -- concessions that have implications for enterprise customers and the industry at large.

Read on for answers to some common questions surrounding the deal and potential fallout. Also, check out our related story for details about the contents of AT&T’s 20-page concession document.

What’s the big deal about the concessions AT&T voluntarily made to the FCC?

The most notable of AT&T’s many concessions are related to net neutrality. The carrier essentially agreed not to charge content providers such as eBay, Amazon or Google a premium to carry their content. AT&T also committed to not treat packets traveling to or from certain Web sites differently than other packets on its network. These concessions go along with principles the FCC set forth in fall of 2005.

How might AT&T’s concessions affect the rest of the industry?

Industry watchers believe other ISPs will have to follow AT&T's lead. The FCC could hold other ISPs to the standard set by AT&T over the next three years.

What are FCC Chairman Kevin Martin’s views regarding net neutrality?

Martin and Commissioner Deborah Taylor Tate issued a joint statement following the FCC approval of AT&T’s merger.

Not only does Martin believe “the conditions regarding net neutrality have very little to do with the merger at hand,” he and Tate say the concessions “very well may cause greater problems than the speculative problems they seek to address.” Essentially, Martin says there isn’t a net neutrality issue. He calls net neutrality an “ill-defined problem.”

Beyond net neutrality, what other concessions are significant?

AT&T agreed not to raise T-1 and T-3 prices in BellSouth territories for two years. The carrier also says it will offer DSL services to new customers at reduced prices starting at $10 per month.

What happens to Cingular Wireless?

AT&T is now full owner of the largest wireless service provider in the United States. Cingular was jointly owned by AT&T and BellSouth. The carrier says it will immediately start selling bundled wireless and wireline services to customers.
