Communications Failure

[Key Stroke]

On my Ademco system, I simply switched telephone lines, and now the
panel displays "Comm. Failure". I am using an RJ31X... the line runs
into it, and into my alarm unit (I have checked to verify polarities
are correct). It then runs from the unit to the rest of the phone
system. Any ideas on what could be wrong, or some tests I can do to
gain more info? I have connected a phone (lineman's handset) via gator
clips to the pairs in the alarm, and I receive a dial-tone. I am new
to alarms so this has stumped me. Any help is appreciated. Thanks!

on a rj31x there is a in and a out...

most of the time poeple invers them

FIRST call the monitoring center before playing with the alarm panel, there
is allready some signal to be sent in the panel buffer and it will send it
as soon as you connect it properly....
to make a simple test , ask someone to creat an alarm on the system while
you listen on the line with your lineman's handset at one of the side of
your rj31x..(try the red/green pair first)

the proper working should be :
before the dialing atempt
there will be a dial tone at the red/green pair and at the exit
pair..(brown/grey on the model i use)

while the panel try to call
you will hear a communication tentative on the red/green pair and nothing on
the exit pair..

if you dont have the dialing atempt on red/green pair and still dial tone on
the exit pair,and no dial tone at the home phone
you plugged it revers..

connect the pair that was going at the red/green at the exit pair and vice
versa..
test it and write back the result...

Unless he has an ADT rj-?? whatever *they* call it. It's backwards.

I'm not sure the sequence of events, but you could have had a comm
failure when you disconnected the first phone line. If the panel is
programmed for it, it detected the phone line disconnect and tried to
call, which of course it couldn't because you hadn't connected it to
the second phone line yet.

Put the system on test the with CS, and try to send signals again. If
they go through, the comm failure will disappear.
