A company that specializes in wireless communications says
it has developed a product that can help users of Voice
over Internet Protocol (VoIP) to keep up communication with
between their alarm system control panel and central
station, as well fix the ability to call 911 service that
may be lost in a VoIP installation. Telular Corp. says its
Telguard® Digital model TG-8 provides E-911 calling to
emergency services and transmits alarm signals to
monitoring stations over next-generation GSM digital
cellular networks.

VoIP – which transmit phone calls over the Internet instead
of landlines – has been a
TARGET=’_blank’>concern in the alarm industry because
of worries over its ability to handle alarm signals and
dial tones.

As a back-up alarm communicator in a traditional
installation, the TG-8 will transmit alarm signals
automatically over the cellular network, should the
telephone line connection to an alarm system become
disrupted or compromised.

“VoIP adoption is spreading rapidly. However, there are
real concerns with VoIP’s ability to provide E-911
services. Specifically, certain alarm transmissions may not
pass through the broadband VoIP connection,” said George
Brody, senior vice president of Telular’s Telguard
division. “Improperly wired installations can
unintentionally disable the security system and some VoIP
providers do not have a direct link to emergency services.
The TG-8 is designed to address these issues.”
