Numerexsolutions;GE-NX8E; GSM Digital Cellular

Problem: Signals (SIA format) from NX8E, via new GE-591E-GSM Digital
Cellular Modules (as well as older analog units), to two different
QuickAlert II's, each in separate locations, are not being
displayed/recorded properly.

For the past two weeks I have been testing the old analog 591E modules
and have discovered that when the cellular signals are received by
NumerexSolutions, the event codes and associated data are displayed
correctly on the GE/Numerex website, but when the same data is
re-transmitted by Numerex to my CO via long distance (using my 888
number), the data is not accepted by the Ozzie, causing Numerex to
retransmit several times, all failures.

When I change the 888 number to my local number in area code 781, the
data from Numerex is correctly displayed/printed.

After much testing of the analog 591E, even bringing my "Test"
QuickAlert II (which I use to bench test all panels/configurations
before installing) to the CO and temporarilly connecting to the 888
numbers, I have come to the conclusion that the SIA data burst sent to
the CO receiver(when dialing the 888 number) is either too fast, or
corrupted by Numerex's re-transmitting equipment, or bad long distance
phone lines, or the long distance phone companies specs don't allow
for these very fast bursts of data (which SIA uses).

Bear in mind that when the signals are sent over land lines (not
cellular) the signals are correctly received! The problem only exists
via cellular, and GE has contracted with NumerexSolutions to handle
the cellular signals from users of the NX591E units.

Though I have spent many hours with GE tech support people and the
Numerex support techs, they have failed to resolve the problem.

I told all the tech people as well as my local GE rep that I would
write a detailed report of my problem, the avenues I took to resolve
it, and my conclusions as to where the problem DOES NOT lie, as well
as where I think the problem really is and who is ultimately
responsible for resolving it.

I have not yet written the report. I decided to try one more
experiment: Since the analog units are being phased out in early
2008, I decided that now is the time to order a few of the new Digital
GSM units from GE and bench test them before swapping them with the
older analog units. Maybe the new units will act correctly when
talking with the Ozzies.

Guess again! Similar problems via cellular; transmissions via land
lines still perfectly fine.

Regardless of which of two Ozzies I send signals to via
NumerexSolutions, and regardless of which phone number is dialed
(local or 888) the data is either not accepted by the receivers or
"uncatologued" is preinted.

Here is what I would like to do: I need one of you who owns one of
the new OH2000E's to permit me to send in a few signals to see if the
signals are received correctly or if they come through corrupted.

With this information I may have a better understanding of the
problem. It could very well be the older QuickAlerts, but I find it
difficult to believe the receivers are at fault, simply because I get
hundreds of valid SIA signals via land line every day.

Best way to reach me is via email: chasbo@xxxxxxxxx

Many thanks.
