In the 1980s the telecommunications industry expected that digital services would follow much the same pattern as voice services did on the public switched telephone network, and conceived a grandiose end-to-end circuit switched services, known as Broadband Integrated Services Digital Network ( B-ISDN ).

The method was developed to replace the Plesiochronous Digital Hierarchy ( PDH ) system for transporting large amounts of telephone calls and data traffic over the same fiber without synchronization problems.

Digital subscriber line ( DSL, originally digital subscriber loop ) is a family of technologies that provide internet access by transmitting digital data over the wires of a local telephone network.

Employees at Bellcore ( now Telcordia Technologies ) developed Asymmetric Digital Subscriber Line ( ADSL ) and filed a patent in 1988, by placing wide-band digital signals above the existing baseband analog voice signal carried between telephone company telephone exchanges and customers on conventional twisted pair cabling facilities.

The E-carrier standards form part of the Plesiochronous Digital Hierarchy ( PDH ) where groups of E1 circuits may be bundled onto higher capacity E3 links between telephone exchanges or countries.

Analog telephone lines are digitally switched and transported inside a Digital Signal 0 once reaching the telephone company's equipment.

Basic Rate Interface ( BRI, 2B + D, 2B1D ) is an Integrated Services Digital Network ( ISDN ) configuration intended primarily for use in subscriber lines similar to those that have long been used for plain old telephone service.

As of 2004, Austria possesses around four million main telephone lines, of which 3. 6 million are analogue main lines, with a further 400 000 Integrated Services Digital Network connections.

Integrated Digital Enhanced Network ( iDEN ) is a mobile telecommunications technology, developed by Motorola, which provides its users the benefits of a trunked radio and a cellular telephone.

Sometime around 1964, this was replaced by a second system built around the Number 5 Crossbar telephone switch ; the lead designer for this project was Alan Kotok, by then a rising star on the design staff at Digital Equipment Corporation ( DEC ).

* Digital Multiplex System, a telephone exchange system

ISDN Digital Subscriber Line ( IDSL ) uses ISDN-based technology to provide a data communication channel across existing copper telephone lines at a rate of 144 kbit / s, slightly higher than a bonded dual channel ISDN connection at 128kbit / s.

Another type of dialer is a computer program which creates a connection to the Internet or another computer network over the analog telephone or Integrated Services Digital Network ( ISDN ) network.

The service can be accessed via Digital terrestrial television ( DTT ) ( DVB-T ), satellite television ( DVB-S ) and cable television ( DVB-C ).

Cellular Digital Packet Data ( CDPD ) was a wide-area mobile data service which used unused bandwidth normally used by AMPS mobile phones between 800 and 900 MHz to transfer data.

Kazaa, including the domain name, was then sold off to Brilliant Digital Entertainment, Inc. Kazaa now operates as a monthly music subscription service allowing users to download unlimited songs.

Two encapsulated forms of PPP, Point-to-Point Protocol over Ethernet ( PPPoE ) and Point-to-Point Protocol over ATM ( PPPoA ), are used most commonly by Internet Service Providers ( ISPs ) to establish a Digital Subscriber Line ( DSL ) Internet service connection with customers.

Digital DTH satellite service is available throughout the country, and accounts for an additional 10-15 % of the market, with only about 5 % being attributed to terrestrial analogue television.

Since then, support for the service has expanded to include other mobile technologies such as ANSI CDMA networks and Digital AMPS, as well as satellite and Landline networks.

Advanced Digital Broadcast ( ADB ) launched its first hybrid DTT / IPTV set-top box in 2005, which provided Telefónica with the digital TV platform for its Movistar Imagenio service by the end of that year.

An online version of the latest edition can be accessed through the paid Westlaw legal information service and as of late 2006, West Academic has published Black's Law Dictionary Digital, 8th edition ( ISBN 9780314176103 ) which has toolbars that integrate with Microsoft Word, Mozilla Firefox and Internet Explorer.

Consumer-oriented ADSL was designed to operate on existing lines already conditioned for Basic Rate Interface ISDN services, which itself is a switched digital service ( non-IP ), though most incumbent local exchange carriers ( ILECs ) provision Rate-Adaptive Digital Subscriber Line ( RADSL ) to work on virtually any available copper pair facility — whether conditioned for BRI or not.

An SAI may also contain a Digital subscriber line access multiplexer ( DSLAM ) supporting DSL service.

The Primary Rate Interface ( PRI ) is a standardized telecommunications service level within the Integrated Services Digital Network ( ISDN ) specification for carrying multiple DS0 voice and data transmissions between a network and a user.

The Integrated Services Digital Network ( ISDN ) prescribes two levels of service, the Basic Rate Interface ( BRI ), intended for the homes and small enterprises, and the Primary Rate Interface ( PRI ), for larger applications.

In his message " The Priest and Pastoral Ministry in a Digital World: New Media at the Service of the Word " to priests for the 44th World Communications Day ( 16 May 2010 ), Pope Benedict XVI called for them to become digital citizens and engage with the information society, saying, " Priests stand at the threshold of a new era: as new technologies create deeper forms of relationship across greater distances, they are called to respond pastorally by putting the media ever more effectively at the service of the Word .... Who better than a priest, as a man of God, can develop and put into practice, by his competence in current digital technology, a pastoral outreach capable of making God concretely present in today ’ s world and presenting the religious wisdom of the past as a treasure which can inspire our efforts to live in the present with dignity while building a better future?

ITV Digital was a British digital terrestrial television broadcaster, which launched a pay-TV service on the world's first digital terrestrial television network.

Started as ONdigital in 1998, the network was briefly re-branded as ITV Digital in July 2001, before the service ceased in May 2002.

Aggressive marketing by BSkyB for their own digital service, Sky Digital, made the ONdigital offer look unattractive.

Had the move been successful, this could have threatened to undermine the fledgling Freeview service, since at the time most digital terrestrial receivers were former ONdigital and ITV Digital units.

This can provide access to Asymmetric Digital Subscriber Line ( ADSL ) Internet service for subscribers who are beyond the normal 4 kilometre signaling limit on a copper wire loop.

Glassey proceeded with his Digital Evidence System which was based on location and digital object control at the service and network layer interfaces.

There are currently five companies in Israel which offer cellular communication service ( with network technology used listed in ): Pelephone and Universal Mobile Telecommunications System | UMTS, Cellcom and UMTS, Partner Communications ( Orange ) and UMTS, Mirs ( HOT Mobile ) and Integrated Digital Enhanced Network | iDEN, and Golan Telecom.
