Now I get to defend the OP.

How do you know that these phone lines aren't for the alarm system at
a business or storage facility in a neighborhood where the crime rate
is higher than one would like?

There could very well be a valid reason why a more robust
infrastructure is required, but where enough noise would raise
suspicions and therefore investigation.

Yup, a friend of mine had a business burglarized where the crooks cut the
phone lines and took other measures to silence the alarm and then watched
from a few blocks away to see if the cops would show up. When no cops came
the thieves returned and looted the place. After that he installed a
cell-phone backup for the alarm so even if the land line was cut the system
would still call for help.

Most low-grade burglars will be stopped just by the alarm sign. The ones
who decide to go in despite the alarm know at least something about keeping
it from working--it doesn't take a master cat burglar to cut the phone line
and watch from a distance to see what happens. If you don't have either a
cell backup or an alarm system that constantly pings the monitoring station
(and triggers a response if it goes silent) then you have a potential
problem.
