the emergency communication business is more technologically
advanced than ever before. Radio communication systems are more
complex and elaborate. Most emergency public service agencies today
operate on digital trunking radio systems. There is also a big movement to provide interoperability communications between local, state,
and federal agencies. This capability gives responders from different
agencies common frequencies to operate on during times of large scale
disasters, mutual aid events, or training exercises. In Montgomery
County a 450Mhz Passport Trunking System provides communications for the
Sheriff Department, EMS, County Fire, and Emergency Management Agency. The Clarksville Police Department and Clarksville Fire Rescue operate
on a 800Mhz EDACS Trunking System. Both of these systems have the
ability to communicate with each other.
Montgomery county is also home for Tennessee
Homeland Security District 7, which includes Stewart, Houston, Cheatham,
Robertson, Dickson, and Humphreys counties. The Passport Trunking system
is networked across all seven
counties to provide regional interoperability.
911 systems also are becoming increasingly
more advanced. When 911 was first introduced, it simply provided a
single number to call for any type of emergency. With
the coming of Enhanced 911 (E-911), not only did you have a single number
to call, but your phone number and address was also provided to
the dispatcher. Today, cutting edge technology
is bringing us Next Generation 911 (NG911). This type
of service gives 911 centers the capability to receive data and calls from several different types of devices. NG911 will give those
in need the ability to send text messages to 911 centers, plus other
devices and services will be able to transmit data such
as crash information, images, and even video.
The Montgomery County E-911
Center now operates the new IP based NG911
system. Once final standards and procedures are set, we will have the
capability to recieve 911 calls from these various devices and formats.
