In some areas VZ will leave the copper in place if you simply ask, and in some
places you must forcefully "insist."
I'm aware of a case in the Tampa area where a subscriber had to "insist." While
he did wind up keeping his POTS lines intact, while adding a second feed in the
way of fiber for Internet access (and video, if it ever gets/got there?), alone,
he advised me that this involves maintaining two accounts with Verizon. And
naturally, this means two monthly bills, as well. One bill will be for the FiOS
service(s), which is(are) the Internet and TV service being offered by
Verizon.net, and the other account (the subscriber's original account) for POTS.
If you suspect that the telco in doing this is merely trying to keep its business
functions separated along the lines of switched circuit vs. IP, and for all of
the regulatory reasons having to do with positioning that that implies, then
you'd be 100% correct.
