Collision The result of two workstations trying to use a shared portion of
a Cat 5 cable simultaneously. The signals “bump” into each
other disrupting both signals. This disruption is represented by
a red light at the Computer Networking Module. If a collision
occurs, the signals are automatically transmitted again. The
entire process takes less than one second, and then the
collision light turns green.
Computer network A number of computers, printers, scanners, and other
computer devices that communicate with one another through
Cat 5 cabling and a shared protocol, such as Ethernet.
Computer Network
Module A specialized printed circuit board on the Home Network
Connection Center that can connect up to four computers.
DBS Direct Broadcast Satellite. A satellite system used in
transmitting TV signals received by home satellite dishes.
Diplexer A device used to split combined incoming video signals
according to frequency. It enables more than one video signal
to be sent to a TV by assigning a signal to a specific channel.
For example, high-frequency satellite signals may be assigned
to one channel and low-frequency TV signals may be assigned
to another channel.
Ethernet A specific type of LAN protocol. Ethernet is a widely
implemented LAN protocol.
ISDN Integrated Services Digital Network. A high-speed telephone
line for transferring large amounts of data at high speeds
(144K).
LAN A local area data communciations network spanning a limited
geographical area (typically within a building). A LAN enables
you to share disks, files, printers, and other devices under a
form of standard control.
LED Light Emitting Diode. Small lights (usually red, green, or
yellow) that indicate electrical activity. LED indicators are on
many of the modules in the Home Network Connection
Center.
LNB Low Noise Blocking Filter located on a satellite disk.
1000 Package
Video/Telcom
Module A combination video amplifier and phone module mounted in
the Home Network Connection Center that receives and
transmits video and voice signals across the home network.
Module A specialized printed circuit board used for a specific purpose.
Modulator A device used to assign video signals to specific channels.
Off-hook When a phone is in use, or off the hook.
