What is Business DSL Service?
DSL stands for Digital Subscriber Line. It is a technology
used for transmitting digital information at high speed on
existing telephone lines to homes and businesses. The technology
converts the single twisted-pair phone line to enable it to
use for high-speed data transmission.
ADSL
(Available now)
ADSL stands
for Asymmetric Digital Subscriber Line.With ADSL technology,
downstream (downloading) data speeds are faster than upstream
(uploading) data speeds. 
TRUE provided
newest hi-speed internets, unlimited hours. Hi-speed internet
is now most popular among organizations which need more effective
of sending and receiving information throughout internet.
Hi-speed internet provides more efficient in speed (10 times
more for 24 hours a day with no holidays) with more economic
than the old system.
Hi-speed
can use with normal telephone line with no connection cost
at the same time it can use the same line as telephone line
during using internet. With excellent speed and unlimited
hours hi-speed internet satisfy most organizations cause more
than one computer can work with it at the same time. TRUE
provided IP for organization benefit as using in mail, FTP
and website and also 24 hours customer support. 
SDSL
SDSL stands
for Symmetric Digital Subscriber Line.
The
technology converts the single twisted-pair used in you regular
telephone line to enable it to receive identical upstream
and downstream speed rates.
Cable Modem Internet
A cable
modem is a device that enables you to hook up your PC to a
local cable TV line and receive data at about 1.5 Mbps. This
data rate far exceeds that of the prevalent 28.8 and 56 Kbps
telephone modems and the up to 128 Kbps of Integrated Services
Digital Network (ISDN) and is about the data rate available
to subscribers of Digital Subscriber Line (DSL) telephone
service. A cable modem can be added to or integrated with
a set-top box that provides your TV set with channels for
Internet access. In most cases, cable modems are furnished
as part of the cable access service and are not purchased
directly and installed by the subscriber.
A cable modem has two connections: one to the cable wall outlet
and the other to a PC or to a set-top box for a TV set. Although
a cable modem does modulation between analog and digital signals,
it is a much more complex device than a telephone modem. It
can be an external device or it can be integrated within a
computer or set-top box. Typically, the cable modem attaches
to a standard 10BASE-T Ethernet card in the computer.
All of
the cable modems attached to a cable TV company coaxial cable
line communicate with a Cable Modem Termination System (CMTS)
at the local cable TV company office. All cable modems can
receive from and send signals only to the CMTS, but not to
other cable modems on the line. Some services have the upstream
signals returned by telephone rather than cable, in which
case the cable modem is known as a telco-return cable modem.
The actual
bandwidth for Internet service over a cable TV line is up
to 27 Mbps on the download path to the subscriber with about
2.5 Mbps of bandwidth for interactive responses in the other
direction. However, since the local provider may not be connected
to the Internet on a line faster than a T-carrier system at
1.5 Mpbs, a more likely data rate will be close to 1.5 Mpbs.
Leading
companies using cable TV to bring the Internet to homes and
businesses are @Home and Time-Warner.
In addition
to the faster data rate, an advantage of cable over telephone
Internet access is that it is a continuous connection.
