APPENDIX H: TELECOMMUNICATIONS GLOSSARY

3G	Third Generation: Intended to be the next great wireless technology, wideband mobile services and applications offering users faster access to the Web.
ADSL	Asymmetric Digital Subscriber Line: DSL service with a larger portion of the capacity devoted to downstream communications, less to upstream. Typically thought of as a residential service.
Advanced Services	Advanced services enable users to send and receive large amounts of information. The FCC defines advanced services as "high-speed, switched, broadband telecommunications that enable users to originate and receive high-quality voice, data, graphics, and video using any technology."
Bandwidth	The amount of data transmitted in a given amount of time; usually measured in bits per second, kilobits per second, and megabits per second.
Bit	A single unit of data, either a one or a zero. In the world of broadband, bits are used to refer to the amount of transmitted data. A kilobit (kb) is approximately 1000 bits. A megabit (Mb) is approximately 1,000,000 bits.
Broadband	A descriptive term for evolving digital technologies that provide consumers with integrated access to voice, high-speed data service, video-demand services, and interactive delivery services. (e.g. DSL, Cable Internet)
Cellular	A mobile communications system that uses a combination of radio transmission and conventional telephone switching to permit telephone communication to and from mobile users within a specified area.
Central Office (CO)	A circuit switch where the phone lines in a geographical area come together, usually housed in a small building.
CLEC	Competitive Local Exchange Carrier: Wireline service provider that is authorized under state and federal rules to compete with ILECs to provide local telephone service. CLECs provide telephone servies in one of three ways or a combination thereof: a) by building or rebuilding telecommunications facilities of their own, b) by leasing capacity from another local telephone company (typically an ILEC) and reselling it and c) by leasing discreet parts of the ILEC network referred to as UNEs.

Competitive Access Provider (CAP)	(CAP, or "Bypass Carrier") A company that provides network links between the customer and the Inter-Exchange Carrier or even directly to the Internet Service Provider. CAPs operate private networks independent of Local Exchange Carriers.
Copper Wire
CPCN	Certificate of Public Convenience and Necessity: Authorization given by the CPUC to telecommunications carriers in order to provide service in the state of California.
CPUC	California Public Utilities Commission
Customer Share	Customer share is the portion of all customers a company has. It is measured by subscribership, lines and/or telephone numbers.
DLEC	Data Local Exchange Carrier; DLECs deliver high-speed access to the Internet, not voice. DLECs include Covad, NorthPoint and Rhythms.
Downstream	Data flowing from the Internet to a computer (Surfing the net, getting E-mail, downloading a file).
DSL	Digital Subscriber Line: The use of a copper telephone lines to deliver "always on" broadband internet service.
DSL lite	Also known as G.lite, this is a version of ADSL that uploads and downloads at speeds that are among the slower of the implementations.
FCC	Federal Communications Commission
GSM	Global System for Mobile Communication. This is the current radiotelephone standard in Europe and many other countries except Japan and the United States.
ILEC	Incumbent Local Exchange Carrier: The traditional wireline telephone service providers within defined geographic areas. Prior to 1996, ILECs operated as monopolies having the exclusive right and responsibility for providing local and local toll telephone service withing LATAs. ILECs include regional Bell operating companies such as Pacific Bell/ SBC and non-Bell affliated companies such as Roseville Telephone Company, both in California.
InterLATA	Between local access and transport areas (LATAs). Services, revenues, and functions associated with telecommunications that originate in one LATA and that terminate in another one or that terminate outside of that LATA. InterLATA services are often thought of as long distance services.
IntraLATA	Within the boundaries of a local access and transport area (LATA). IntraLATA services typically include local and local toll services.

ISDN	Integrated Services Digital Network: An alternative method to simultaneously carry voice, data and other traffic, using the switched telephone network.
ISP	Internet Service Provider: A company providing Internet access to consumers and businesses, acting as a bridge between customer (end-user) and infrastructure owners for dial-up, cable modem and DSL services.
IXC	Inter-Exchange Carrier: Typically defined as a long-distance telephone company. IXCs provide long distance services to customers between LATAs by using their own facilities or by reselling to their customers the long distance services they have purchased from another carrier.
Kbps	Kilobits per second: 1000 bits per second. A measure of how fast data can be transmitted.
LATA	Local Access and Transport Area: A geographical area within which a divested Regional Bell Operating Company (RBOC) is permitted to offer exchange telecommunications and exchange access services.
Local loop	A generic term for the connection between the customer's premises (home, office, etc.) and the provider's serving central office. Historically, this has been a wire connection; however, wireless options are increasingly available for local loop capacity.
Mbps	Megabits per second: 1,000,000 bits per second. . A measure of how fast data can be transmitted.
Number Porting	Number porting allows customers to switch between telephone service providers while retaining their original telephone number. Also called Local Number Portability (LNP).
Paging	A one-way communications service from a base station to mobile or fixed receivers that provide signaling or information transfer by such means as tone, tone-voice, tactile, and optical readout. Two-way paging allows the user to send data as well as receive it. In some cases, a two-way pager can serve as an alternative to a cellular telephone.
PCS	Personal Communications Service: A low-powered, high frequency (1.9 GHz) alternative to traditional cellular service, including CDMA and GSM.
POTS	"Plain Old Telephone Service:" Basic telephone service, including dial tone, the ability to place and receive voice/data calls over the same basic lines.

RBOC	Regional Bell Operating Company: A telecommunications carrier created to provide local service after the divestiture of AT&T in 1984. While there were initially 7 RBOCs created 1984, due to mergers there are now four: BellSouth, SBC, US West/Qwest, Verizon.
Resale	The practice of carriers purchasing of telecommunications services from another carrier at wholesale rates and, then, reselling those services to their own customers at retail rates.
RTU	Remote Terminal Unit: The location at which there is a transition between a telecommunications carrier facility and the local lines serving the individual customers
Section 271	Section 271 of the 1996 Telecommunications Act allows certain Regional Bell Operating Companies (RBOCs1) to enter the long distance market after they each prove that they have opened their respective local markets to competition.
Subscribership	Subscribership is how many customers have subscribed for a particular telecommunications service.
Switched Network	A domestic telecommunications network usually accessed by telephones, key telephone systems, private branch exchange trunks, and data arrangements. (Also PSTN - Public Switched Telephone Network)
TA `96	The Telecommunications Act of 1996: TA '96 gives the FCC general rulemaking authority to set the ground rules and policies for local competition. It also assigns states the responsibility for implementing many of the statutory and federal regulatory requirements of the Act, either jointly with the FCC or on their own.
TD	The Telecommunications Division of the California Public Utilities Commission
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.
UNE	Unbundled Network Elements: Leased portions of a carrier's (typically an ILEC's) network used by another carrier to provide service to customers.
Upstream	Data flowing from your computer to the Internet (sending E-mail, uploading a file).

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 palm devices. 2) Broadband Internet service provided via wireless connection, such as satellite or tower transmitters. (Also Wireless Broadband)
