Tier 3 Internet Network: A network that solely purchases transit/peering from other networks to participate in the Internet.
Trunk Level 1 (T-1): A digital transmission link with a total signaling speed of 1.544 Mbps. It is a standard for digital transmission in North America.
Trunk Level 3 (T-3): 28 T1 lines or 44.736 Mbps.
TTY: A type of machine that allows people with hearing or speech disabilities to communicate over the phone using a keyboard and a viewing screen. It is sometimes called a TDD.
Unbundling: The term used to describe the access provided by local exchange carriers so that other service providers can buy or lease portions of its network elements, such as interconnection loops, to serve subscribers.
Universal Service (Also known as Universal Lifeline Telephone Service): The financial mechanism which helps compensate telephone companies or other communications entities for providing access to telecommunications services at reasonable and affordable rates throughout the country, including rural, insular, and high costs areas, and to public institutions.

Upstream: Data flowing from your computer to the Internet (sending E-mail, uploading a file).
V-Chip: System built into TVs that allows users to screen out, based on television ratings, programs they do not want household members to watch. Those subscribers with older TVs may need to purchase a set-top box that utilizes V-Chip technology in order to access this feature (see Parental Lock Capability).
Very High Data Rate Digital Subscriber Line (VDSL): Technology that employs an asymmetric form of ADSL, with projected speeds of up to 155 Mbps.
Very High Frequency (VHF): The part of the radio spectrum from 30 to 300 megahertz, which includes TV Channels 2-13, the FM broadcast band, and some marine, aviation, and land mobile services.
Video Description: An audio narration for television viewers who are blind or visually disabled, which consists of verbal descriptions of key visual elements in a television program, such as settings and actions not reflected in the dialog. Narrations are inserted into the program’s natural pauses and are typically provided through the Secondary Audio Programming channel.
Video On Demand: A service that allows users to remotely choose a movie from a digital library and be able to pause, fast-forward, or even rewind their selection.
Virtual Local Area Network (VLAN): A network of computers that behave as if they are connected to the same wire even though they may actually be physically located on different segments of a LAN.
Virtual Private Network (VPN): A software-defined network offering the appearance, functionality, and usefulness of a dedicated private network.
Voice over Internet Protocol (VoIP): A technology that allows users to send and receive voice calls using an Internet connection instead of a phone line.
WiFi (Wireless Fidelity): A technology that uses radio transmissions to enable electronic devices to connect to a wireless local area network (LAN).
WiMAX: A wireless technology through which wireless Internet access is provided with a significantly larger range than regular WiFi. WiMAX can provide broadband service up to 30 miles.
Wireless: Telephone service transmitted via cellular, PCS, satellite, or other technologies that do not require the telephone to be connected to a land-based line.
Wireless Internet: 1) Internet applications and access using mobile devices such as cell phones and handheld devices. 2) Broadband Internet service provided via a wireless connection, such as satellite or tower transmitters.
Wireless Internet Service Provider (WISP): An ISP that provides service through a wireless network.
Wireline: Service based on infrastructure on or near the ground, such as copper telephone wires or coaxial cable underground or on telephone poles.
