Comparing T1 Bandwidth To DSL

I was recently asked the following question comparing T1 bandwidth to DSL.

"...isn't a T1 a better value per achieved throughput than DSL?"

My answer ... not necessarily. It depends on what you are trying to accomplish. If you are dealing with pure throughput, DSL has the advantage because you can get higher speeds on DSL than with T1. But, there are pros and cons to each that should also be weighed.

DSL is distance sensitive. If you can't see your local CO, then your speeds could be reduced below that of a T1. T1 speed is constant and not distance sensitive.

DSL is considered "shared" bandwidth in that you merge your traffic at the DSLAM with other DSL users. T1 is dedicated bandwidth.

DSL can be synchronous (SDSL) or asynchronous (ADSL). T1 is synchronous.

DSL usually has a much lower service level agreement with regard to uptime and repair time vs. T1.

DSL is usually much less expensive than T1.

T1 is a bigger line capable of sending larger amounts of data than the DSL line; therefore, the amount of data transfer on a T1 is faster and throughput is increased from better productivity and resource.

Beware comparing T1 and DSL purely on cost and throughput. Last time I checked, US regulations required the owner of "the last mile" of wire to respond to failures within 4 hours for T1, but allowed a much longer response window (I think 24 hours ... maybe longer) for DSL.

Find out what the response window currently is for each. Then consider how much it would hurt your business to lose its broadband (and telephone if you use VOIP) for that long. You may decide cost per megabyte of throughput is not as important as potential downtime.

If you're interested in finding out what your options are for T1 ... including a comparison of over 40 providers ... simply request a free quote here - -

with DSL, consumer do NOT get any kind of bandwidth availability guarantee but T1 line is vastly different. Consumer have a written guarantee that you are getting 1.5 MB up and 1.5 MB speed
