Problem with GEM-P3200 and phone service

[jweinberg@xxxxxxxxx]

Greetings!  I have a Napco GEM-P3200 which has been trouble-free for
many years.  Last week I ran into trouble with the phone service in my
house.  Basically after 4 rings on incoming calls, the line would go
dead.  My answering machine was set to pickup on the 5th. ring, so I
never got any messages.

I thought the was with the answering machine, so I purchased a new one,
only to find that the problem persisted.  I unplugged all phones and
answering machines and the problem was still there, but when I
unplugged the P3200, the probem went away.  I retested a few times and
now know conclusively that the P3200 is the problem.

I checked all of the connections and they seem fine.  I was hoping that
there was some sort of modem board on the unit that I could easily
replace, but it looks like the modem is integrated onto the circuit
board.  Do I have any options other than to replace the entire unit?
If not, how difficult is it to move the programming from the old unit
over to the new one?

Thanks,

Jonathan
