The code I read for this area (and yours may differ of course) didn't
specifically say a POTS line was required. It said any electronics
required for the alarm have to be protected from power failures for some
certain number of hours (4 maybe? 8?). A copper POTS line meets that
requirement with no caveats. Cellular built into the alarm panel also
naturally would.
I think the catch with fiber is who's responsible for battery backup on
the ONT? You can't trust the customer to do it because they often can't
or won't monitor it. The provider *can* have an ONT with a battery
backup, and they *can* monitor it. But are they doing that? As long as
someone is addressing all that, then it's not specifically a code
issue....at least not in this locality.
With that said, the reason I don't want to make any promises about
alarms doesn't really have to do with code, it's just that sometimes you
get a 1980's (or older) system and it seems like it doesn't want to work
when it's on an ATA no matter what I do. In this particular case, the
burglar alarm panel works fine, but there's a panic button in the
building which also calls the alarm company. They say the alarm company
gets a call when you push the panic button, but the signals it sends are
"garbled". I don't want to deal with that stuff, but I was giving it
the ol' college try. The person on site said something about a line
"stealer" or "isolator" switch and it tickled dusty memories. It's
probably nothing to do with anything. I've moved on.

Tell them it is required by fire code to be on a POTS line not a VoIP
line. While that isn't true everywhere, in many places it is (just
like emergency elevator phones).
You may look into getting a resale account with the phone company for
POTS lines so you can bundle that in.

I had one of those "my antique alarm system doesn't work on your ATA,
and I know you said get a POTS line for the alarm but I ignored you"
calls.
Was trying to troubleshoot that. Nothing major.

What are you trying to accomplish? My Alarm panel has this built in

I didn't realize how many varieties of such a thing there might
be.....I guess I'll have to get eyes on it.

Line Exclusion device. I found a few online. I remember putting
one on the
hall phone at a school. It was on one of the main lines of the
school. The
kids could use the hall phone unless someone in the office was
using that
line. Saved them from buying another line.

Oh, geeze.... I remember how they worked.... line isolator?
Exclusion something. Privacy adapter. Something like that.
Line excluder? Exclusion device. Automatic exclusion.
Seems like the word exclusion was in there. Google it and you will
probably
find one.
There are also line sharing devices that would block another line
if a fax
was in use.

What's the proper term for a device that will take over a phone
line if the
phone connected to it picks up? Like the device they use to put an
elevator
emergency phone onto the fax line.
