Variations of Broadband DSL for Business and Residential Applications

Broadband internet access, also referred to high-speed internet access, provides businesses and consumers, internet access at considerably higher rates of speed than standard dial-up modems. Broadband does not simply pertain to one specific type of internet service or data transfer rate. Broadband is continually changing and developing, and it encompasses a wide range of technology including fibre optic cable, cable modems, Wi-Fi (wireless fidelity), WLAN (wireless local area networks), and DSL (digital subscriber lines).

Digital Subscriber Lines, or "DSL," uses the existing customer phone lines to provide internet or intranet access to businesses and homes using high-speed broadband technology of varying levels.

Broadband DSL works by Tmnetcom subscribers to a main broadband DSL access multiplexer. The broadband DSL multiplexer sends a signal from the broadband DSL customer phone line to a network, which then in turn connects the subscriber to the internet.

Broadband DSL use digital technology by compressing sizeable quantities of video, audio, and data into what is known as "bits." The bits are transformed into graphics, text, and other information which are transferred at high rates of speed to business and home computers across the globe.

At the uppermost level, the two primary categories of DSL are asymmetric and symmetric. Residential broadband DSL typically uses asymmetric variations which include RADSL, UADSL/G.Lite, and ADSL. Data transfer rates are considerably slower upstream than downstream, so this type of broadband DSL, ADSL, is suitable for residential use where surfing the internet is the primary internet activity. Residential internet users generally have more
incoming than outgoing data.

Symmetric varieties of broadband DSL, SDSL, are IDSL and HDSL. These broadband DSL variants are suitable for most business applications. Upstream and downstream transfer rates are the same, making SDSL technology suitable for server hosting, video conferencing, LAN applications, file transfers, and email.

Motorola's Broadbandcom an unusual reputation for "flip" Bluetooth headsets, most recently with the MOTOPURE H15 -- and if you're into that sort of thing, pay attention, because they've got another one coming down the pike. The H17 becomes Moto's smallest flip headset (we doubt anyone else is even competing for that title), measuring 54 x 17 x 10mm when open with CrystalTalk, voice prompts, multiple ear bud options, micro USB charging, and a power toggle controlled by the action of the flip. We'd still take an HX1 before this, but if you're game, it should be available by the end of the month.

Motorola H17 latest in company's line of flip headsets originally appeared on Engadget Mobile on Mon, 21 Sep 2009 22:17:00 EST. Please see our terms for use of feeds.
