coaxial cable	A type of wire consisting of a center wire surrounded by insulation and a grounded shield of
(coax)	braided wire. The shield minimizes electrical and radio frequency interference.
DOCSIS	The CableLabs Data-Over-Cable Service Interface Specification defines interface standards
	for VoIP 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 VoIP cable 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 the TCP/IP protocol route messages based on the destination IP address. Your cable service provider assigns your VoIP cable 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 VoIP cable modem. You need to provide the MAC
	address to your cable service provider.
MHz	Mega Hertz. A measure of radio frequency - millions of cycles per second. One MHz means
	one million cycles per second.
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 protocols that provides 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 source is a power supply designed to protect mission-critical
	networks against power outages, brownouts, surges, and spikes.

VoIP

Home

Universal Serial Bus is a computer interface for add-on devices such as printers, scanners, and VoIP cable modems. When you connect your SURFboard VoIP cable modem to the USB port, Windows 98 and later versions automatically recognize the VoIP cable modem.

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.
