What You Need To Know About Cable Modem Connection
The internet is so popular that almost everyone is so familiar with
it. Even those who are just in grade school can relate to people talking
about it. It is so good to know that children who where born in this
time and age are aware of the beauty of the Internet. Not only the
intelligent nor the brilliant people can make testimonials about how it has
sure made our lives easy but even the ordinary human beings as well.
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.
With this, definitely we became aware of what cable modem connection is
and what it provides. In addition to the faster data rate, an advantage
of cable over telephone Internet access is that it is a continuous
connection. So, better check out a cable modem and test it for your own
satisfaction.
