Glossary

coaxial cable	A type of wire consisting of a center wire surrounded by insulation and a grounded shield of braided wire.
(coax)	The shield minimizes electrical and radio frequency interference.
DOCSIS	The CableLabs Data-Over-Cable Service Interface Specification defines interface standards for cable
	modems and supporting equipment.
download	To copy a file from one computer to another. You can use the Internet to download files from a server to
	your home PC. A DOCSIS digital voice modem downloads its configuration from a server during start-up.
downstream	In a network, downstream describes the direction of data received by your computer from the Internet.
Ethernet	The most widely used type of local area network (LAN). The most commonly installed Ethernet networks
	are called 10Base-T. 10Base-T provides transmission speeds up to 10 megabits per second (Mbps),
	usually over twisted-pair wire. Fast Ethernet (100Base-T) provides transmission speeds up to 100 Mbps.
expansion slot	An opening in a computer where a circuit board can be inserted to add new capabilities.
F-type connector	A connector used to connect coaxial cable to equipment.
IP address	An Internet Protocol address is an identifier for a computer or device on a TCP/IP network. Networks
	using TCP/IP route messages based on the destination IP address. Your cable provider assigns your
	digital voice modem an IP address to provide a continuous Internet connection.
MAC address	The Media Access Control Address uniquely identifies each device that can be connected to an Ethernet
	network. It is permanently written to read-only memory (ROM) at the factory and printed on the rear
	panel of your SURFboard Digital Voice Modem. You need to provide the MAC address to your cable
	provider.
MHz	Mega Hertz. A measure of frequency - millions of cycles per second. One MHz means one million cycles
	per second.
PBX	A private branch exchange is a private telephone network usually used within a business. Users of the
	PBX share a certain number of outside lines for making telephone calls external to the PBX.
PSTN	The public switched telephone network is the traditional circuit-switched, voice-oriented telephone
	network originally invented by Alexander Graham Bell. It is sometimes referred to as plain old telephone
	service (POTS).
RJ-11	The most common type of connector for household phones.
RJ-45	The most common type of connector for Ethernet networks.
splitter	A splitter is a device that divides the signal power from an input cable equally between two or more
	signals, each carrying a selected frequency range.
TCP/IP	Transmission Control Protocol/Internet Protocol is a set of standards and rules for communication
	between networks.
upstream	In a network, upstream describes the direction of data sent from your computer to the Internet.
UPS	An uninterruptible power supply provides a battery backup to enable voice service to continue for some
	time during a power outage.
USB	Universal Serial Bus is a computer interface for add-on devices such as printers, scanners, and digital
	voice modems. When you connect your SURFboard Digital Voice Modem to the USB port, Windows 98
	Second Edition and later versions automatically recognize the digital voice modem.
VoIP	Voice over Internet Protocol is a method to exchange voice, fax, and other information over the Internet.
	Voice and fax have traditionally been carried over traditional telephone lines using a dedicated circuit for
	each line. VoIP enables calls to travel as discrete data packets on shared lines.
