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.
