Hooked up a customer yesterday that was pulling 15mb downstream 8mb up.. he was also able to watch television over the phone line.. I thought that was pretty interesting. The guy was actually an engineer for Bellsouth and said the service is on trial in Cobb County right now and should be available next year.
From what I saw the line was capable of 20mb and he said they are working on 50mb right now, there are just distance issues with that.
