THE
PROBLEM
The National Oceanic and Atmospheric
Administration (NOAA) mission is to protect
life and property, and enhance the United
States’ economy. NOAA’s National Weather
Service is the sole official voice of
the U.S. government for issuing public
safety warnings during life-threatening
weather situations. Their technology
requires a dedicated 4 Wire analog connection
from their source stations to a broadcast
point in the field to provide critical
emergency information to the public.
These circuits require a constant analog
carrier tone to be delivered from the
source to the transmitter, which is interrupted
during voice transmissions. Due to the
forthcoming phase out of copper wire
line based phone circuits, and these
phone lines becoming less dependable
and requiring longer time for repair
of down circuits – they must be replaced
with more economical and reliable service.
The problem - how to move the existing
analog based signaling system from a
copper phone line based service to a
cost effective, secure, dependable digital
IP backhaul without disrupting the existing
network or requiring an expensive forklift
up grade?
THE SOLUTION
The Encore Networks BANDIT-3™ router
providing Internet Protocol (IP), VPN,
Firewall, Ethernet Switching, legacy
serial protocol with analog circuit
interworking using an integrated 3G
cell modem. A single box solution that
supports traditional 2/4 Wire analog
circuit interworking to an IP solution,
without changing any equipment in the
field while preserving the invested
CAPEX. The BANDIT-3™ 4 Wire interface
supports the analog tone frequency
requirements, while packetizing it
for transmission over the 3G cellular
network using a secure VPN with IPSEC
encryption to ensure end to end security.
The switch from a copper phone line
to a cellular data connection was done
simply by unplugging the existing analog
equipment from the copper line and
terminating it on the BANDIT-3™. With
its Ethernet Switching ports, the BANDIT-3™
is able to deliver IP/Ethernet based
services at anytime at a fraction of
the cost.
