What
is T-1 |
|
| |
Most of us are
familiar with a normal business or residential line from the
phone company. A normal phone line like this is delivered on
a pair of copper wires that transmit your voice as an analog
signal. When you use a normal modem on a line like this, it
can transmit data at perhaps 30 kilobits per second (30,000
bits per second).
The phone company moves nearly all voice traffic as digital
rather than analog signals. Your analog line gets converted
to a digital signal by sampling it 8,000 times per second at
8-bit resolution (64,000 bits per second). Nearly all
digital data now flows over fiber optic lines, and the phone
company uses different designations to talk about the
capacity of a fiber optic line.
If your office has a T1 line, it means that the phone
company has brought a fiber optic line into your office (a
T1 line might also come in on copper). A T1 line can carry
24 digitized voice channels, or it can carry data at a rate
of 1.544 megabits per second. If the T1 line is being used
for telephone conversations, it plugs into the office's
phone system. If it is carrying data it plugs into the
network's router.
A T1 line can carry about 192,000 bytes per second --
roughly 60 times more data than a normal residential modem.
It is also extremely reliable -- much more reliable than an
analog modem. Depending on what they are doing, a T1 line
can generally handle quite a few people. For general
browsing, hundreds of users are easily able to share a T1
line comfortably. If they are all downloading MP3 files or
video files simultaneously it would be a problem, but that
still isn't extremely common.
A T1 line might cost between $1,000 and $1,500 per month
depending on who provides it and where it goes. The other
end of the T1 line needs to be connected to a web server,
and the total cost is a combination of the fee the phone
company charges and the fee the ISP charges.
A large company needs something more than a T1 line. The
following list shows some of the common line designations:
|
|
| |
- DS0 - 64 kilobits per second
- ISDN - Two DS0 lines
plus signaling (16 kilobytes per second), or 128
kilobits per second.
- T1 - 1.544 megabits
per second (24 DS0 lines)
- T3 - 43.232 megabits
per second (28 T1s)
- OC3 - 155 megabits
per second (84 T1s)
- OC12 - 622 megabits
per second (4 OC3s)
- OC48 - 2.5 gigabits
per seconds (4 OC12s)
- OC192 - 9.6 gigabits
per second (4 OC48s)
