SDSL vs. fractional T1

[wardog25]

If my company switched from a 384kbps SDSL line to a 384kbps fractional T-1, would I see any speed differences? Would there be less slow-down when lots of users are on?

 

[jgideon]

No, I would not expect it to be any difference. I would expect fewer outages tho.

Surely the main difference will be in the costings. I can't get sdsl where I'm located, but then looking at the prices, thats not a bad thing.

Being a ISP, the only real difference is PRICE and PRIORITY. On most backbones T1 connections are routed first.

Dont forget what the upload speed is on your SDSL. You said your download is 384Kbps, but what is your upload? Your upload speeds could possibly be faster with the fractional T1.

IO:
SDSL stands for "Symmetric DSL". So the upload and download speeds are identical at 384Kbps.

wardog,
I wouldn't bet on there being a major difference between the two, but if the price is about the same, I'd go with the fractional T1.

so hold up, if all 1.5M lines are the same, how come an SDSL business line costs $289, but I can get a cable internet line for $40 a month that is a 1.5M line?

I know a cable line shares its bandwidth with neighbors, but it is still pretty fast. So a business pays $200 extra a month for a line that doesn't go down quite as often? sounds strange to me.

 

[lgarner]

Not really. Business users need constant uptime and consistent performance. $200 seems like a small price to pay for that, if SDSL can live up to the demand.

For higher availability, there's the (fractional) T1 approach, which costs more still.

First of all, you are comparing two different technologies. Price is not based on performance necessarily. Second, other factors like static IP addresses, dedicated backbones, guaranteed bandwidth and premium support all play a role in price. Maybe the extras don't mean much to a home user and his $40 cable connection alternative, but for a business it could be critical.

The problem with Cable Modem is reliability, not to mention that a cable modem is generally 128k upload speed max. Which in a company environment, that bottleneck is a killer. A T1 or SDSL have the same upload and download.

Guarenteed Uptime, Static IP Addresses, Premium Support - all those they mentioned are part of the higher package.

If I could afford it, I would have a T1 to my house.

When you buy a T1, look to spend about $300/month. Depending on your area of course, and what provider you choose. Try to stay away from Mom & Pop ISP shops, especially if they are not protected by a Generator.

Our ISP is one of those crapshops, and I can't seem to convince MGMT to change, because it's a friend...
