Hello,

I am looking for a 56k soft modem with a usb interface that could be used t
o complete contact ID protocol to call a local alarm company. I found that  
the CX90240 chip by Conexant has the ability to put the modem into "alarm m
ode", where the kissoff and handshake tone are detected automatically. I ha
ve not able to identify a modem using this chip though.

I was wondering if anyone has suggestions on where to find this modem or ho
w to complete contact ID protocol without this specific chip?

I am able to send the DTMF tones, but not sure how to receive the kissoff a
nd handshake tone or what mode to put the modem into using the MS+ AT comma
nd.

I appreciate your help greatly.

I would imagine that it is difficult ----- and maybe impossible to find  

After all, it is certainly something that shouldn't be available to just an
yone. Central station receivers are pretty exclusive and secure for a reaso
n Don't you think?

Really?  I bought 4 receivers through this group and nobody ever checked  
my credentials.

Wasn't there a plugin PC modem card that would convert a desktop PC into  
a receiver?

I know.  I know.  What the OP was asking might lead more to a device you  
could hook to the phone line and fake a kiss off.  Given more and more  
systems are using cellular, radio, and IP reporting this would not be a  
sure fire way to beat reporting.  On anything worth protecting almost  
certainly not.

FYI:  I can just off the top of my head think of a simpler way to fake a  
kissoff.

"Really, what's that Bob."

Um, I don't think I ever shared the backdoor I found into older P1632  
programming either.  As recently as last year I think I might have found  
a way to do it with newer P1632 panels, but since I was just helping a  
tech for another company (I didn't tell him what I thought I had just  
done) and I'm totally out of the business I never bothered to setup to  
test it.  I don't think I even have any P1632 boards left I could use to  
test it with.

Hmmmm.... now I am intrigued.  LOL.  I wonder if it would work with a  
1664.  I think I have one of those still NIB sans keypad.

Gee Whiz Bob, you do know that, curiosity killed the cat, right!!

If you plan on doing this testing evaluation on your lunch break
well OK then!!!   You have a lot of custom parts that need attention
so that you will be compensated for you detailed work.  :-)

Interesting choice of words.........  "people".....

That would suggest maybe men, women, children, friends, neighbors,
X-Wives, lady down the street, guy across town, foreigners, aliens,
..........and...... others??

Would you care to break that down a bit??  :-)

I can remember a few girls in high school who I pursued to -- no avail.  
But .... there were so many girls and so little time ..... (sigh)

and numerous times by my wife through the past 50 years --- (to no avail) :->

I just simply refuse to "pack up and leave"  

It's my house too ! ! ! !

And for a long time I had my eye on the "lady down the street" that you mentioned .... but now she's the one with the Monmouth ass.

Ya know? I was just thinking ---- as I was going to respond to you ----  
that lately every thread just seems to deteriorate from technical messages  
down to frivolous inanities. And I think I'm the instigator.
  
On the other hand, with so few participants in the group now days, I fear t
hat the lack of posts just might prove to be it's demise. Some times we'll  
go a whole week with out any posts. Social Media groups have made this venu
e obsolete, so I don't see any possibility of it ever rising from the ashes
.  

I do not participate in ANY of the social media groups save one having to d
o with my local area so I can keep abreast of local events. But I take a ve
ry low key placid position and don't make any waves. Mostly just observe an
d absorb information.  

Does anyone here participate in any other alarm or technical centric groups
 that maybe we few remaining mc-crudgeons could migrate to ?  

My feeling is that we few remaining have a wealth of experience that would  
be nice to pass on to ..... who? someone? anyone? Is there anyone out there
 who's interested anymore?  

If anyone is interested in carrying on with this subject maybe the first re
sponder should start a new thread.  

Wada ya think?

I use to be a member of a couple communication contracting related  
forums, but I don't even recall their names.  I've never been a member  
of any Reddit, Facebook, or LinkedIn groups related to this field.

Same here,
I had a Group on Yahoo way back n the day.
(but it turned into a local chat group for kids.)
I don't believe in the site thing,
(to many moderators and others are always trying to make money off what  
your talking about..)
I'll be on the N.G.'s as long as their there..  ;-)

ASA Future Discussion or Something Else??

Jim, I am somewhat the same as you on the social stuff.  The only
technical group I am on to any great degree is
https://www.contractortalk.com/f58/

The link will take you to the Low Voltage forum.  For the most
part I go there to get opinions on certain challenges that I might
be dealing with.  Some of which I post here as well.  Or depending on
the question (as here) I will answer in the hopes that it helps others.

There are number of Forums that are related to specific equipment.
I have registered on those sites in order to get notifications of
new questions that may come up.  I generally just read those and
answers until they go off on a variety of tangents which seems to
be the norm.  At which point I just ignore.

As for the postings here on ASA going off on a tangent I am just as  
guilty or lets say "I helped!!".  ;-)

I agree that ASA is going going gone.  It has been that way for a
number of years.  It ain't what it use to be.  Now that we have
to wear a mask and with social distancing it will only get worse...

As for OP starting a new thread.  I doubt that will happen.  As I see it
somebody new comes here and ask a question.  It is unknown if they
ever make it back to see if anyone has provided an answer or not since
he has not responded one way or the other.  Maybe he got his answer
somewhere else.  Since newsgroups don't track or require registration
there is no way to know anything more that somebody asked a question.

So Jim, what do you suggest??  We all just fade into the woodwork or
something more dramatic??

BTW I changed the Subject to see if helps.  :-)

I've been subscribed to this DIY Forum for quite some time. It's got some i
nteresting questions that come up and there are some pretty experienced peo
ple answering questions. You'll have to navigate to the alarm section which
 is quite extensive.

I just don't get much of a chance to participate because I think that most  
of the responders have nothing else to do all day but respond to the posts  
in this forum. It's no sooner than someone asks a question and there are th
ree or four responders that never give anyone else a chance to respond. I o
nly get to look at it once a day and by that time all the questions are ans
wered. But ------ it IS interesting to review what's going on. Once in a gr
eat while, I'll get an opportunity to inject a reply, but not often.

By the way Les, one thing I was never good at and that is "fading" ;->

However, my wife and I have talked about "when that time comes" we should g
o and rent a Rolls Royce convertible, convert all our assets into cash, put
 the cash in the back seat, put the top down and drive the car off a cliff  
at the Grand Canyon.  
Can you just picture that?
What a way to go ---- Huh?   :-0

Its a long way down, but before you get there its likely some cop will  
just take your money and car along the way under civil asset forfeiture  
laws and let you hitch hike the rest of the way to the grand canyon broke.

Jim,

I was out of town for two days.  Trying to catch up.
Very slow at doing so!!!

I checked out the DIY site.  This is a site that I would just read from
time to time and try and resist answering or contributing.  It would be
very time consuming as was another I was involved with years ago.

If I somehow had nothing to do but sit at my computer and read and type
then maybe.................. but, no..............

I did notice that some respond to a question just to respond.  
Regardless of the fact that what they said was they don't know
anything about the question.  LOL.

Thanks for the link.  I did register just so that I could receive
a notification of an answer to a particular question of interest.

BTW the trip to the Grand Canyon may have a lot of merit.  :-)

Later,

Les

Instead of using a modem that will likely NEVER work why not just set up a  
test panel and use it to send Contact ID
