Digital Enhanced Cordless Telecommunications (DECT), known as Digital European Cordless Telephone until 1995, is an ETSI standard for digital portable phones (cordless home telephones), commonly used for domestic or corporate purposes. It is recognised by the ITU as fulfilling the IMT-2000 requirements and thus qualifies as a 3G system.
Local loop unbundling (LLU or LLUB) is the regulatory process of allowing multiple telecommunications operators to use connections from the telephone exchange's central office to the customer's premises. The physical wire connection between customer and company is known as a "local loop", and it is owned by the incumbent local exchange carrier (also referred to as the "ILEC," "local exchange," or in the United States either a "Baby Bell" or an Independent telephone company).
Standard-definition television (or SDTV) is a television system that has a resolution that meets standards but not considered either enhanced-definition television (EDTV) or high-definition television (HDTV). The term is usually used in reference to digital television, in particular when broadcasting at the same (or similar) resolution as analog systems. In the USA, SDTV refers to digital television broadcast in 4:3 aspect ratio, the same aspect ratio as NTSC signals.
Broadband Internet access, often shortened to just broadband, is a high data rate Internet access—typically contrasted with dial-up access using a 56k modem. Dial-up modems are limited to a bitrate of less than 56 kbit/s and require the full use of a telephone line—whereas broadband technologies supply more than double this rate and generally without disrupting telephone use.
Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone.
Broadband open access is an issue of policy debate in telecommunications, regarding whether or not companies which own broadband telecommunication infrastructure (such as cable operators) should be required to provide access to their facilities for competing businesses which do not own physical infrastructure. The issue came to the fore in the U.S. in 1998, when AT&T announced its plan to acquire TCI, then the nation's largest cable operator.
