APN: An Access Point Name (APN) provides access to an
external network. By default, the SIM Card in your terminal is
configured with the APN of your Service Provider. You may
want to configure further APN's if you have arranged with your
Service Provider to use more than one SIM Card.
BGAN Satellite Terminal: Referenced throughout this
document as the Satellite Terminal, "The Terminal," or UT.
This device implements and manages BGAN satellite
communications between your computer and Service Provider's
network.
Quality of Service: Quality of Service (QoS) assigns a level of
priority to certain types of data traffic, in particular high
bandwidth applications such as video and multimedia. QoS
attempts to maintain a guaranteed throughput level, and
minimize error rates and end to end latency, so providing a
higher level of service than "best effort" protocols.
DNS Server: The Domain Name System (DNS) is an Internet
service that is required because the Internet does not recognize
the text-based Web address or email address that you type into
your Web browser or email application. All or part of a Web
address or an email address is a domain name, and DNS
translates this domain name into an IP address that is recognized
by the Internet.
A DNS Server holds a database of domain names and IP
addresses, so that when you enter a Web address or email
address, you are directed to the correct IP address over the
Internet.
Ethernet: Ethernet is a local area networking method used
widely throughout the computer industry. It is one of the three
communications interfaces supported by the Satellite Terminal.
Fault Code: A number which uniquely references an error in a
hardware or software system. In the Satellite Terminal, if there is
a fault detected, the fault code and a description are displayed in
suitable LaunchPad windows.
GPS: Global Positioning System. The GPS receiver in the
Satellite Terminal receives signals from the constellation of GPS
satellites. It uses these signals to determine the Terminal's
location on earth. That location is used during registration to
gain access to the BGAN system.
