VDSL stands for Very High Bitrate Digital Subscriber Line. T-1 AMI/B8ZS was a two-pair (four-wire) technology with limited reach, requiring a signal regenerator (repeater) 3,000 feet from the central office and another every 6,000 feet. Both a digital subscriber line (DSL) and cable internet services offer higher speeds than technologies such as dial-up modems. An ADSL (Asymmetric Digital Subscriber Line) is one of the types of DSL broadband communication technology. Four factors are driving the interest in G.SHDSL: G.SHDSL quickly has caught on in European markets, and the major North American local exchange carriers will roll it out soon. Similarly, it converts the voice signals that it receives, into digital data. Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. When it comes to choosing between cable and DSL internet services, people often times have a lot of issues choosing which one is best. DSL transmits an internet signal through regular phone lines, but it’s not the same as the noisy, outdated dial-up system you may be thinking of. DSL internet service may run on the same wires that deliver landline phone service, but that’s where the similarity to dial-up internet ends. G.SHDSL combines the positive aspects of existing copper-based, high-speed communications with the benefits of increased data rates, longer reach and less noise. It’s simple — fiber is fast. In the rest of the world, business applications are typically served by E-1, at 2.048M bit/sec. The latest news, reviews, how-tos and more. No one type of the connection is the broadband.
