T1 vursus 1.5 meg cable / DSL connection? Why so much?

A T1 is 1.544 mbps. A T1 costs like $370 a month. I have a 1.5 mbps cable connection and I pay $40 a month for it. So why is there such an extreme difference in price, and why would anyone pay 6x more for a T1 when they could get like a 80 mbps cable connection for that much?
 
Like I said a T1 is 1.5 mbps.

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

But still, 1.5 megabits per second is not fast for $370 a month. You say that the upload speed matches the download speed and that’s why its so expensive. Well you can get a 8 meg down 728 kbps up connection from my local ISP for $60 a month. So say you double that you will have 1.5 mbps up (the speed of a T1) and 16 megs down still for less then half of what a T1 costs.

So obviously there must be something else...
 
No, it's easier for the servers of the ISP to be dealing with a lot of downstream traffic, hence the higher down speeds for real cheap, but being able to handle the same upstream speed as downstream speed does require a little more infrastructure. Elmarco is right.
 
Yes, ITs 1.5mbps download like your cable line would be, except its also 1.5mbps up speed where your cable would probally be around 50-200kbps
 
i get around 8 megs of cable internet...
which only 7.5 are used most of the time...

I pay 55 a month...
u just gotta shop around..
 
Ok but you guys are not getting my point. This is my point:

T1: 1.5 mbps up, 1.5 mbps down, $370
Cable: 3 mbps up, 32 mbps down, $200

Those are average estimated prices. It is UNCANNILY clear which is the better option. So obviously there MUST be some other difference then cable otherwise it would not be 3x more expensive for the same amount of upload and download bandwidth as cable.
 
I would LOVE to see the cable plan that has 50mbps upload speed.

edit: well i see you changed it right before i posted i guess, but i would still love to see this normal cable plan with 32 down and 3 up and sources to where you are gettijng these prices from.
 
Because of the Perceived Performance Quotient (PPQ)? :P

A T1 is a direct line from the servers to you. No coils. No switches. No nothing. No shared bandwidth. No distance limitations. Just pure bandwidth goodness.

Cable is shared bandwidth. Everybody in the neighborhood is on the same grid. If you all download at the same time of day, your speeds will be a fraction of what is advertised. So, big business goes to a T1 or higher.

But a 50 up / 3 down mbps cable connection will still severally outperform a T1 even at the most active time of the day and for much less money. I have a 1.5 mbps connection and the slowest I have ever dropped to is about 1.2 mbps.

These are our local internet prices.

8 Meg x 768 KB $59.95/month

4 Meg x 512 KB $49.95/month

1.5 Meg x 384 KB $39.95/month

768 KB x 256 KB $29.95/month

128 KB x 128 KB $19.95/month

So an 8 meg down / 768 meg up connection is $60 a month. So say you had a price limit of $370 being that’s about what a T1 costs. Well if you take 8 Meg x 768 KB $59.95/month times 6 you get:

48mbps down / 4.6 mbps up for $360. And I am sure if you wanted that much bandwith my ISP would give a discount. So that’s more the double of the upload speed of a T1 and more then 10x the download speed of a T1 for less then a T1...

Thats true, but remember, you can't combine them into one huge connection, and i'm sure the ISP can't give you a 48/4.6 connection, but you never know.

Why couldn’t they? Most cable modems support up to 100 mbps and with the newer 10/100/1000 Ethernet cards I am sure there is a cable modem that will support 10/100/1000 mbps.

And why couldn’t you combine them into one huge connection? Coulden’t you just plug the output of the cable modem into a router like a D Link and plug the computers into the router and call it a day?

The modems may be able to, but I don't think your ISP could set aside that much bandwidth just for you, using the infrastructure thats set up.

You can say, give each computer its own internet connection, but you cant take 6 cable lines and turn it into 1 large cable line.
 
T1 has 24 channels of 1.5 up and down simultaneous. DSL has one channel only and the up is slower then the down. T1 are built for greater loads, and are a direct line, no pppoe. :)

But right here...

DS0 - 64 kilobits per second
T1 - 1.544 megabits per second (24 DS0 lines)

...it says a T1 is 24 DS0's and a DS0 i only 64k. So thus isin't the whole T1 is only 1.5 megs not 24 channels of 1.5 megs.

They might not have the infrastructure for 40 megs but they obviously do have it for 8 megs. So say I just paid double of what they are asking for the 8 meg connection I could get 1.5 meg up and 8 meg down and it would still be less then half of the cost of a T1 and it would have the same upload speed and 4x the download speed. Any ISP can support a 1.5 meg up / 8 meg down connection.
