Target audience
This notice is intended for customers with home security systems
and high speed Qwest DSLTM installed on the same line.
The exponential growth and demand for
high speed DSL connectivity creates a situation where DSL
needs to operate in a variety of environments. At
Qwest, we are constantly evaluating the new ways our
customers use our service and are taking proactive steps in
notifying our customers about our discoveries. Just like DSL
service, home security systems found their way into many households
in the U.S. It is reasonable to expect that a certain number
of homes will have a home security system installed on the
same line that is also used for DSL.
Home security systems have been around
for a long time. Many installations predate the deployment of
residential DSL. In fact, some of the alarm systems were built prior
to the dramatic growth of the Internet and may not have been designed
to anticipate the new ways telephone lines are used to deliver high
speed DSL connectivity to our customers. Both new and old security
systems may have special wiring requirements to properly operate with today's
technology.
Home alarm systems use the telephone line by utilizing the portion of
the line carrying the voice conversation (the frequency spectrum between 0-4 kHz).
On the other hand, DSL uses the capabilities of the telephone line
that are not used by the regular
telephone conversation (which is above 4 kHz) for the delivery
of high speed data. Since some of the alarm systems may not
have been designed to perform under such conditions, it is
important to test your alarm system.
Does this affect me?
Every customer
having a home security system installed on the same line
as the DSL service may potentially be affected. Thus, we strongly
recommend that you perform a test of your home alarm system.
You must check with your security company for the processes
they recommend. In general, performing a test of the alarm
system should indicate if the service is working correctly.
Most security companies recommend regular testing to ensure
the system is working, even when DSL is not present on the
line.
If you do NOT have an alarm system
or have an alarm system installed on a different telephone line
than the DSL service, then you are not subject to any special
wiring requirements described on this web page.
What do I need to do if the alarm
system is not working?
If testing indicates the security
system is not working, your alarm system may be malfunctioning
or you have special
wiring needs and require a professional installation.
Qwest does not have the capability to perform tests on
your alarm system. Thus, you must contact your home security
provider to identify the source of the problem. If it is determined
you require a special wiring solution, Qwest strongly
recommends you obtain help from a qualified professional to
perform this installation or repair. Please contact your security
company to perform professional installation services. You
may also request a Qwest
technician install to perform the installation. (A technician
installation charge may apply.)
The home security system and the Qwest DSLTM
can exist on the same customer line. However, you
must follow precisely the instructions above to make sure
that both of your services will perform to your expectations.
