"Not exactly".  They are required to do it only 'to the extent permitted by
existing facilities'.  To wit, if they need that wire pair to provide service
(say, an additional line) to a paying customer, they _can_ physically disconnct 
the 'inactive account' premises, and hook up the new paying account to that
pair.

On occasion, telcos are known to re-use the pair, by just hooking the new
customer onto it, _without_ pulling the bridge clips at the 'multiple' where
the old custmer was connected.   This leads to all sorts of messes.  the 'non-
customer' discovers dial-tone on the pair and starts using it.  Calls are being
made which the _real_ customer didn't make, which leads to real arguments with
the billing department.  Then, the customer picks up their phone, and instead
of getting dial tone, discovers a conversation _in_progress_ on the line -- when
_nobody_else_ at their place is on the phone.  Strangely, the parties to that
conversation refuse to identify themselves, and one of them is _really_ anxious
to terminate that call, so you can use "your" line.

I, personally, have been through this more than once, in older, high-density
housing neighborhoods.
