What does ADSL stand for?
- Asymmetric Digital Subscriber Line. ADSL is a modem technology that transforms ordinary phone lines (also known as
"twisted copper pairs") into high-speed digital lines for ultra-fast Internet access. ADSL also enables access to corporate
networks for telecommuters, as well as exciting new interactive multimedia applications such as multiplayer gaming, video on
demand and video catalogs.
How does ADSL work?
- ADSL modems use digital coding techniques to squeeze up to 99% more capacity out of a phone line without interfering with
your regular phone services. That means you could be simultaneously talking on the phone or sending a fax - while surfing the
World Wide Web.
How fast is ADSL?
- ADSL provides speeds up to 8 Mbps downstream (to the user) and up to 1 Mbps upstream, depending upon line length and loop
and line conditions.
What are the main benefits of ADSL?
-
- Simultaneous Internet and voice/fax capabilities over a single telephone line
- Uninterrupted, high-speed Internet access that's always on-line
- Cost-effective solution for residential customers, telecommuters and small businesses
- Data Security that exceeds other technologies
What is the market for ADSL?
- ADSL enables two general types of applications -- interactive video and high speed data communications. Interactive video
includes movies on demand, other video on demand such as delayed TV segments, video games, video catalogs, and video
information retrieval. Data communications covers Internet access, telecommuting (remote LAN access), and specialized network
access. The strength of ADSL compared to other high speed transmission alternatives (such as cable modems or Fiber To The
Neighborhood (FTTN) lies in the number of existing telephone lines -- now approaching 750 million -- compared to new cabling
which has reached comparatively few homes and almost no small businesses.
When is the market for ADSL?
- ADSL services are being deployed in several areas around the world already. Millions of people can now take advantage of
this broadband service.
Can I get ADSL today?
- In many regions around the world today you can get ADSL service, and access providers are eager to offer it in more
areas.
How will telephone companies price ADSL services?
- Due to anti-trust regulations, the ADSL Forum can not discuss this matter. However, announcements from access providers
suggest that they intend to be competitive with Cable Modem pricing.
What will ADSL do to ISDN?
- That all depends upon the telephone companies offering both services. The two services are not the same -- ISDN provides
two voice channels or a 128 Kbps data channel while ADSL is predominantly a data pipe providing an asymmetrical bandwidth of
up to 8 Mbps downstream and 1 Mbps upstream under good conditions. However, an ADSL access network will be an overlay network
and therefore will not require the expensive and time-consuming switch upgrades that held ISDN back for so long. If ADSL
service prices resemble ISDN service prices, then one would expect ADSL to be favored for Internet and video
applications.
Can the Internet keep up with so much speed?
- The Internet infrastructure is constantly being upgraded to handle the rapidly increasing use of the Internet. Many
servers operate at 56 Kpbs. In addition, the Internet backbone has grown in an unplanned fashion and a connection may see 20
or more routers, creating significant delay, and for TCP connections, bandwidth throttling. However, a great deal of work is
underway to (1) increase server access speeds, (2) improve backbone and NAP bandwidth, (3) increase router speeds, and (4)
introduce ATM into the backbone for much lower latency. Futhermore, many Internet service providers will implement proxy or
cache servers for frequently visited web pages, creating local access at least for these pages. At the very least, ADSL will
make many Internet experiences far much better than voice band modems and the resulting market pressures will inevitably lead
to capacity increases.
How does ADSL compare to cable modems?
- ADSL provides a dedicated service over a single telephone line; cable modems offer a dedicated service over a shared
media. While cable modems have greater downstream bandwidth capabilities (up to 30 Mbps), that bandwidth is shared among all
users on a line, and will therefore vary, perhaps dramatically, as more users in a neighborhood get online at the same time.
Cable modem upstream traffic will in many cases be slower than ADSL, either because the particular cable modem is inherently
slower, or becasue of rate reductions caused by contention for upstream bandwidth slots. The big difference between ADSL and
cable modems, however, is the number of lines available to each. There are no more than 12 million homes passed today that
can support two-way cable modem transmissions, and while the figure also grows steadily, it will not catch up with telephone
lines for many years. Additionally, many of the older cable networks are not capable of offering a return channel;
consequently, such networks will need significant upgrading before they can offer high bandwidth services.
What is xDSL?
- XDSL is the name which as been coined for the family of digital subscriber line technologies ranging from HDSL through to
VDSL with ADSL firmly in the middle of the speed/capacity band.
What is the controversy between CAP and DMT line codes?
- CAP and DMT are two "line codes" or modulation systems currently on the market today for ADSL. The Forum has taken no
position on the merits or demerits of either. Each line code has its own case to make. All major ADSL vendors belong to the
ADSL Forum and set aside their differences while working together to create system guidelines and market positions. As such,
it can be fairly represented that the line code issue will have little bearing on the size, speed, or character of the ADSL
market as a whole.
What is CAP?
- CAP stands for Carrier-less Amplitude/Phase modulation, and describes a version of QAM in which incoming data modulates a
single carrier that is then transmitted down a telephone line. The carrier itself is suppressed before transmission (it
contains no information, and can be reconstructed at the receiver), hence the adjective "carrier-less."
What is DMT?
- DMT stands for Discrete Multi-Tone, and describes a version of multicarrier modulation in which incoming data is collected
and then distributed over a large number of small individual carriers, each of which uses a form of QAM modulation. DMT
creates these channels using a digitial technique known as Discrete Fast-Fourier Transform. DMT is the basis of ANSI Standard
T1.413.
What is DWMT?
- DWMT stands for Discrete Wavelet Multi-Tone, and describes a version of multicarrier modulation in which each carrier is
created by Wavelet transform rather than Fourier Transform.
What does ADSL offer the Internet service provider?
- Today, high speed Internet access is seen by many as the first "killer" application of ADSL - there is a pent up demand
for higher access speeds and only ADSL can practically provide these speeds. Today's analog modems routinely offer 28.8 Kbps
or 33.6 Kbps and, in a few but growing number of instances, up to 56kbps. However, 56 Kbps is probably the practical limit
for analog modems. ISDN can increase this to 128 Kbps but this is still slow compared to ADSL speeds of between 1.5 Mbps and
8.0 Mbps. ADSL will open a whole new world of virtually instantaneous downloading of massive graphics and even video
applications over the Internet.
