You can try it if your phone has a switch labeled "Tone/Pulse". Switch
it to pulse and dial a phone number (your cell) and see if the call goes
through after it gets through with all the clicking. I sell and service
telecom systems so I know how it works. ^_^
Mine works in Baltimore. I just tried it again. I still have a
standard black phone, as well as other phones. I think once they've
designed a pcb or chip that handled both pulse and touch-tone, it
probably costs no more than a penny extra to keep the pulse circuit.
Of course some day they'll want a new circuit, like maybe with fios,
and then they may not write a new pulse circuit.
Some lines maybe, but I don't think any around here are going out more
that Retired posted says " your back-up battery will provide you with
power for voice service for up to 8 hours."
Seems ambiguous. I'd be happier if it said voice usage. I"m under
the impression that I have "phone service" even when I'm not using the
phone. Still it is hard to believe that a " 12-Volt 7.2 Ah SLA
Sealed Lead Acid battery" would run down in only 8 hours of non-use.
Plus that's with a fully capable battery. Sealed lead acid
batteries get old and hold less charge as time goes on.
One more thing I have to keep track of, and then do.
On some ONT's there is a power jack on the side of the battery pack
where you can plug power from an auto or marine battery which would give
you a couple of days of phone. In my case of 11 days without power,
Verizon automatically transferred all of my incoming land line calls to
my cell phone.
