    According to the chap we've just signed a two-year contract with, our two new ADSL 2+ lines will be uncontended, so we shouldn't have to share bandwidth with anyone. I don't know if the quoted upload speed is what we'll actually get, mind, but at least it shouldn't vary from hour to hour. I figure we can use the upload bandwidth from both our ADSL lines either by having different services using different lines (Moodle server on one, Etherpad and VPN on the other, maybe) or by using round-robin DNS and having alternate DNS requests resolve to different IP addresses. A web server such as Apache will listen out on multiple interfaces at once, so you can have the same web site / application served by two interfaces with different IP addresses.

    What is it the original poster needs lots of upload bandwidth for, exactly? We've just had a look at this sort of thing ourselves, and figured we could solve a lot of issues simply by hosting our "brochure" website on an external hosting service, which is a lot cheaper than sorting out a fixed line to your premises.

    DSL and T1 lines are two types of digital data transfer services. DSL services are considerably cheaper and may offer faster but less consistent download speeds. T1 lines have fast, consistent download and upload speeds.

    It's obvious by the vast difference in price between DSL and T1 that they are not the same.This is the most noticeable difference between DSL and T1 lines is the price. T1 subscription prices can be as much as 10 times more than DSL subscription prices. In addition, laying a T1 line to a service location costs considerably more than installing DSL on a pre-existing phone line..T1, weighing in at over $500 per month, has a throughput of one and a half megabits per second (1.5 Mbps). DSL, with an average price point of less than $100 per month, also claims 1.5 Mbps speeds.

    In addition to the price difference and type of delivery, a T-1 comes with a stronger commitment to deliver service. Almost all carriers provide a SLA (service level agreement) that guarantees uptime of your T-1. The SLA generally outlines a credit structure for any time that your T-1 is down.

    DSL is a distance-sensitive service which means that the distance for DSL is measured in cable length to a carrier's Central Office.But T1, on the other hand is readily available in almost all areas, business or residential.
