Glossary License

download	To copy a file from one computer or other network device to another. You can use the Internet to
	download files from a server to your home computer. Your voice gateway downloads its
	configuration file and firmware from Vonage.
downstream	In a cable data or DSL network, the direction of data received by your computer from the Internet.
driver	Software that enables a computer to interact with a network or other device. For example, there are
	drivers for printers, monitors, graphics adapters, modems, Ethernet, USB, and many others.
DSL	A digital subscriber line enables a broadband connection to the Internet over traditional telephone
	lines that support DSL. You need a subscription for DSL service from your local telephone company.
dynamic IP	An IP address that is temporarily leased to a host by a DHCP server. The opposite of static IP
address	address.
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.
F-type connector A type of connector used to connect coaxial cable to equipment such as the VT2142.
firewall	A security software system on the VT2142 that enforces an access control policy between the
	Internet and the VT2142 LAN.
flow	A data path moving in one direction.
GUI	graphical user interface
HFC	A hybrid fiber/coaxial cable network uses fiber-optic cable as the trunk and coaxial cable to the
	subscriber premises.
host	Any computer or similar device supporting end-user applications or services with full two-way
	network access. Each host has a unique host number that combined with the network number forms
	its IP address.
hub	On a LAN, a device that connects multiple hosts to the LAN. A hub performs no data filtering. See
	also router.
IGMP	Internet Group Management Protocol
Internet	A worldwide collection of interconnected networks, all using TCP/IP.
IP	Internet Protocol is a set of standards that enable different types of computers to communicate with
	one another and exchange data through the Internet. IP provides the appearance of a single,
	seamless communication system and makes the Internet a virtual network.
IP address	An Internet Protocol address identifies a computer or other device on a TCP/IP network. Networks
	using the TCP/IP protocol route messages based on the destination IP address.
IPSec	The Internet Protocol Security protocols are authentication and encryption standards for secure data
	exchange over the Internet.
ISP	Internet service provider
LAN	A local area network provides a full-time, high-bandwidth connection over a limited area, such as a
	building, campus, office, or home. The computers and other devices you connect to your voice
	gateway, except for the telephones, form a LAN. Ethernet is the most widely used LAN standard.
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

your VT2142.

MHz

MPPC

Mega hertz. A measure of frequency; one MHz means one million cycles per second.

Microsoft Point-To-Point Compression protocol is a method for compressing PPP packets to optimize processor and bandwidth usage for many simultaneous connections. MPPC is patented in the United States by Hifn Inc.

MPPE	Microsoft Point-to-Point Encryption is a protocol for encrypting data across PPP and VPNs. It is
	frequently used in conjunction with MPPC.
NAT	Network Address Translation is a standard for a LAN to use one set of IP addresses for internal
	traffic and a second set of IP addresses for external traffic.
