How fast is ADSL2+?
24 Mbps
ADSL2 can achieve downstream data rates of up to 12 Mbps speeds at its source while ADSL2 can achieve up to 24 Mbps. ADSL2/2+ are best suited for longer loop lengths. ADSL2 can reach distances of up to 5,000 meters while ADSL2+ can achieve up to approximately 6,000 meters.
What ADSL stands for?
Asymmetric Digital Subscriber Line
Asymmetric Digital Subscriber Line (ADSL) is a technology that provides high transmission speeds for video and voice to homes over an ordinary copper telephone wire.
What does the term asymmetric mean in DSL?
In ADSL, bandwidth and bit rate are said to be asymmetric, meaning greater toward the customer premises (downstream) than the reverse (upstream). Providers usually market ADSL as an Internet access service primarily for downloading content from the Internet, but not for serving content accessed by others.
What are the technologies used in ADSL?
Features of ADSL The telephone company uses a Digital Subscriber Line Access Multiplexer (DSLAM) at its end office so that multiple ADSL users can be connected to the high-speed backbone network. The most common technology uses FDD. Here two separate bands are used for upstream and downstream communications.
Is ADSL a Fibre?
ADSL uses telephone lines to transmit data along copper cables from your nearest telephone exchange to your home or office. Fibre Internet – sometimes referred to as ‘superfast broadband’—uses fibre optic cables to transmit data.
Is DSL better than ADSL?
ADSL has download speeds that are considerably faster than upload speeds. DSL is more generic, implying any type of Digital Subscriber Line service, from ADSL where the upload and download speeds are different, to symmetric digital subscriber line (SDSL) in which the upload and download speeds are the same.
What is the bandwidth of ADSL?
ADSL offers speeds of up to 8Mbps (Megabits per second) downstream and 448Kbps upstream (832Kbps on business lines).
What is the difference between ADSL and SDSL?
ADSL differs from the less common symmetric digital subscriber line (SDSL). In ADSL, Bandwidth and bit rate are said to be asymmetric, meaning greater toward the customer premises (downstream) than the reverse (upstream).
What are the different types of ADSL?
ADSL initially existed in two versions (similar to VDSL ), namely CAP and DMT. CAP was the de facto standard for ADSL deployments up until 1996, deployed in 90 percent of ADSL installations at the time. However, DMT was chosen for the first ITU-T ADSL standards, G.992.1 and G.992.2 (also called G.dmt and G.lite respectively).
What is the difference between broadband and DSL?
The various forms of digital subscriber line (DSL) services are broadband in the sense that digital information is sent over multiple channels. Each channel is at higher frequency than the baseband voice channel, so it can support plain old telephone service on a single pair of wires at the same time.
What is broadband in analog video distribution?
“Broadband” in analog video distribution is traditionally used to refer to systems such as cable television, where the individual channels are modulated on carriers at fixed frequencies. In this context, baseband is the term’s antonym, referring to a single channel of analog video, typically in composite form with separate baseband audio.
