I live in a large apt. building in SF, and already have basic local phone service from AT&T, via an old land line. A few other residents already have Sonic for their provider (I don't know them, but see via my wifi-connect list, there are some Sonic users). The landline box is located in my building's basement, with wires all over the place, like a nest.
I was under the impression that all that needs done, since I already use an AT&T landline, is to plug in the DSL splitter to my phone jack, and connect one of the lines to my phone, and the other to my laptop. And, of course, set up my connection via the operating system.
Anyway, I'm curious as to what, exactly, the AT&T technician may need to adjust or check on? Thanks for any help.
