Putting my modem on ATT network

[Hextejas]

I am fairly sure that ATT won't want me to do this but I am interested in the technical side of it.

How does ATT know it's mine and not theirs ? MAC address registration somewhere ?

Thanks

Since AT&T provides instructions on how to do it, I doubt that they care.

Well I'll be darned.

Thanks

Whoops, I spoke too soon. This is for DSL and not cable. The document specifically says to buy one from ATT
