Chapter 1 - Introduction
System Components
The TracPhone V7 system includes the following components:
The antenna unit provides the satellite link
between the onboard modem and the land-
based hub. Using its integrated GPS,
advanced reflector technology, and gyro
stabilization, the antenna automatically
locates and tracks the correct satellite, even
while your vessel is on the move.
The control unit supplies power to the
antenna unit, links the antenna to the
modem, and allows you to operate and
configure all aspects of the system.
The modem, manufactured by ViaSat, is the
transceiver and "brain" of the system. It
processes all incoming and outgoing TCP/
IP data between the antenna and the switch
using its proprietary spread spectrum
technologies. It also powers the antenna's
transmission and reception components
(BUC and LNB).
The multimedia terminal adapter (MTA) is
a Voice over IP (VoIP) device that allows
you to connect up to two analog telephones
and make and receive calls over the mini-
VSAT Broadband connection.
The switch links the system to your onboard
local area network (LAN) via wired Ethernet
connections. Four of its eight ports support
Power over Ethernet (PoE) - they can supply
power to any IEEE 802.3af-compliant device.
If you connect a wireless access point to the
switch, be sure to apply security settings
(such as encryption) to protect the network.
The remote service and support module is a
compact GPRS cellular modem. This unit
allows KVH Technical Support to "dial in"
to your system for troubleshooting
purposes.
