I'm starting to have second thoughts getting a T1 line installed for my business. I mean, our DSL is rated at 6.0/768 and since web hosting and e-mail is outsourced, the up doesn't concern me as much. Since T1 is 1.5 up and down, I want to know if there's any advantages not related to speed regarding T1 and ADSL. The ADSL is cheaper so why not go with that?

If your business does not have the need then on a cost basis alone the DSL is the way to go. I have done the same thing while networking business offices and as long as your not consistantly hitting 100% usage don't worry about it. Keep track of your peak usage and drive your bw requirement as needed.

It depends on what your business is. Is it crucial that you have access to the internet? If you are unable to retreive your email for a period of time, will that be a problem? Will you host other services (VPN) inside your network that you'll need access to 24x7? We have a T1 for our internet connection but we need reliability more than speed for those exact reasons.

yeah, but if something does happen a T1 has tons of diagnostics along the line that can quickly piinpoint a problem and get it resolved.
now if a DSL provider can guarantee service levels the same as a T1 is, then fine. Otherwise T1s still dominate business because of their reliability.
The DSL is about 120 plus change. The T1 is included in a 700/month package that includes our phone lines which is the added bonus. We just gotta figure out whether or not our long distance usage justifies the package (it is very up and down so there's no real way to tell month to month).
Usually T1 lines alone run for about what 350 or so?
I thought about the whole reliability thing. I was chatting with a specialist at Covad and he basically told me that response times typically are under 4 hours for T1. However, I've never had our Speakeasy ADSL connection fail for more than that if at all in the 2 years we've had them for service. Their uptime is impressive. What made me think about it was when I visited the MPOE and peaked around. It seems like everyone on our floor is running a T1 line so I thought perhaps there was some kind of advantage I wasn't aware of (better fidelity of signal, more flexibility in the future, etc.). Our DSL is great though we're only about a mile from the C.O. so it's running pretty close to it's rated speed.
Fenix: I have no idea if fiber optics is an option in our area.

it depends on what you are using broadband access for and if any of it is mission critical.
i have clients that have site to site vpns and apps running over those vpns and they want to tell me that they don't really "need" a T-1.
i have a few clients that are currently using DSL for Site to Site VPN's and believe me DSL is NOT as reliable as T-1 no matter what some people in this thread are trying to say.
as if that is in ANYWAY relevant whatsoever.

What sort of business is this? If it has any sort of size to it T1 will do it justice. If you have say, 5 employees, business DSL should be fine. If you can afford T1, go for it. It's worth it.
BTW there is no comparison. If you have the money T1 is leaps and bounds better than DSL.

The only down side is a T1 is pretty slow these days at only 1.5 Mbs. It's common to use multiple T1s bundled together. There is a point at around 6-8 T1s where one moves to a T3 however as it's the same cost. A 6 Mbs T3 is still faster than a 6 meg T1 bundle.
But with metro ethernet offerings offering gobs of bandwidth for cheap, it isn't a bad idea to just use two metro providers, that way if one fails you're still good.
Trust me on this, get something with an SLA. A few of my customers have Internet through a local cable ISP, and we average 2 outtages a month with an average downtime of 20 minutes. In addition, the DNS servers that they provide are severely overloaded (resolving a site like google to an IP takes as long as 5 seconds) so we have to run our own off the colo.
QFT. In most small business situations, the speed is not an issue, people browse the net to do research and download emails. 180k/sec is plenty of speed for that.
