T1 Line

Clarifications

You are covered with this T1 line

as bandwidth. How much bandwidth does each user need on a consistant basis and a peak basis?

A T1 line is roughly about four mega bit or will support eight users with 56K bandwidth. By itself, around 500k byte of usage by a single user. Pretty slow by most standards but this is duplex, or the same speed both directions.

The T1 "line" that comes
into your building (depending on _its_ technology) probably has 24
individual pairs of wires. Where I work, the T1 we have has 24
voice-grade lines that combine into one "fatter pipe".

You'll have a router that connects your computer network to your T1
line. Depending upon the setup of your internal computer network you
can have a (virtually) unlimited number of computers use the T1 for
internet access.

The T1 technology uses 24 channels to transmit the signal from your
building to your provider but these channels are combined together to
provide you the total speed of your T1.
When you download something at full speed, you can notice that the
speed of download is the one of a full T1, meaning that it is not 1
user= 1 channel, but all users=all channels.
Basically, you should not worry about channels when it comes to data.
You basically have a 1,544Kbps symetrical (same speed download/upload)
that can be shared up to the numbers of cables you can put on your
switch (of course it s always possible to add more swithces for more
users)
The channel division can be a relevant information if you use your T1
also for the voice lines (phone). each line uses one channel, which
means your data line get slower every time a line is used for phone
(by exactly 1,544/24 for each line occupied)

So basically a channel is a digitized cable that can be used for a
voice line or data up to 1,544/24 Kbps. a T1 line is a tube large
enough to contain 24 of these channels, so that means 24 phone lines
or a combined total of 1,544 Kbps ( the router combines these channels
together for data to add the speed).

It does not matter how many users you have. you will see a comparable
decrease of speed when you add your 25th user than when u added your
21st
Happy computing. :)
