Phone Card Providers
The largest sector of the telecommunications industry continues to be made up of wired telecommunications carriers. Establishments in this sector mainly provide telecommunications services via wires and cables that connect customers’ premises to central offices maintained by telecommunications companies.
These companies also maintain the cable network that connects different regions of the country as well as foreign countries, and forms the backbone of the industry. While voice used to be the main type of data transmitted over the wires, wired telecommunications service now includes the transmission of all types of graphic, video, and electronic data mainly over the Internet.
These new services are made possible through the use of digital technologies that provide much more efficient use of the telecommunications networks. One major technology breaks digital signals into packets during transmission. Networks of computerized switching equipment route the packets. Packets may take separate paths to their destination and may share the paths with packets from other users. At the destination, the packets are reassembled, and the transmission is completed. Because packet switching considers alternate routes, and allows multiple transmissions to share the same route, it results in a more efficient use of telecommunications capacity as packets are routed along less congested routes.
In today’s dismal telecom environment, it is important for a concerned telecom customer to find a reputable broadband service provider to power their communication services or replace their existing failing provider. Customers can comparison-shop with many of the finest providers who offer various connectivity solutions such as AT&T, Sprint, Verizon, SBC, BellSouth, SAVVIS, Allegiance Telecom, Covad, Epoch Internet, NTT/Verio, NewEdge Networks, MegaPath Networks, DSL.net, EarthLink, DirecTV Broadband, AT&T Broadband, and more.
