Hughes R-BGAN User Manual

DHCP: Dynamic Host Configuration Protocol. DHCP is a communications protocol that lets

network administrators manage centrally and automate the assignment of IP addresses

in an organization's network. Using the Internet Protocol, each machine that can

connect to the Internet needs a unique IP address. You must make sure that the
Windows network settings on your PC are set to allow the network to choose IP settings

automatically.

Discoverability: In the Bluetooth interface, this term refers to the ability of Bluetooth-based

devices to “find” each other when they are in the same proximity. On the Satellite IP
Modem Control Pad Bluetooth screen, by enabling or disabling discoverability, you can

determine whether the Satellite IP Modem is discoverable or not discoverable by other

devices using Bluetooth.

DNS: Domain Name Service, a static, hierarchical name service for TCP/IP hosts. The network

administrator configures the DNS with a list of host names and IP addresses, allowing users

of workstations configured to query the DNS to specify remote systems by host names
rather than IP addresses. On the Satellite IP Modem Control Pad Network Settings screen,

a primary and possibly a secondary DNS address supplied by your Service Provider must

be assigned.

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 IP

Modem.

Fault Code: A number which uniquely references an error in a hardware or software system. In

the Satellite IP Modem, if there is a fault detected, the fault code and a description are
displayed at the bottom of the Modem Control Pad Home and Status screens.

GPS: Global Positioning System. When the GPS receiver in the Satellite IP Modem gets a bearing

on a GPS satellite, the receiver computes and stores the Modem’s location on earth.

That location is used in the Pointing Process to obtain your location relative to the
Regional BGAN Satellite.

Inmarsat Regional BGAN Satellite IP Modem: Referenced throughout this document as the

Satellite IP Modem, this device implements and manages Regional BGAN satellite

communications between your computer and Service Provider’s network via one of the
three supported interface methods – USB, Ethernet, or Bluetooth.

Interface Lights: The interface lights on the Satellite IP Modem panel – USB, Ethernet, and

Bluetooth – 1) indicate the state of the currently-active interface during Normal

Operational Mode, or 2) serve as a bar graph to indicate relative signal strength during
Pointing Mode.
