DSL, Cable, Or T1 Bandwidth .... What's Right For Your Business?

Deciding what is the right bandwidth configuration for your company's voice/data network is a common issue. It's not always obvious either .... but it can be.

The common question considered is “Isn’t DSL or Cable sufficient for my office?”.

Well ....this depends upon the size of your company and how you’re going to use the bandwidth. If you have 10 or more employees all using an internet connected computer plus a telephone line each, it would be advantageous to have a full T1 installed.

T1s are usually the preferred choice of communications for businesses that have moderately high bandwidth needs with many users (upwards of 40 with low/moderate use) AND that require a stable, reliable, constant connection.

A T1 line can send a gigabyte of information in less than 10 seconds and since the upstream/downstream bandwidth is symmetrical, it has the capability of many simultaneous "conversations" or voice/data/video connections within.

Whether it's for internet access or telephone service, your T1 will have an average uptime of near 100%, compared to DSL and Cable which can randomly experience outage problems throughout the day, whether it's for a split second or several minutes/hours- mostly due to the line being shared, oversubscribed, and of lower quality. Many T1 carriers will even guarantee a certain level of uptime such as 99.9% (for internet connectivity) secured with a contract called an SLA (Service Level Agreement) which will reimburse you with a credit for that month should the line become interrupted for any reason.

If you're planning on operating a Voice over IP (VoIP) phone system, T1 will provide much better call quality compared to DSL and Cable because a T1 is a dedicated connection to your local phone company’s central office, and unaffected by excess bandwidth usage from your neighbors- as a result: lower latency and higher throughput.

In other words ... T1 Bandwidth is usually a better choice for many reason. With the recent drop in prices ... add cost effectiveness to the answer too.

I am confused. My company is presently using a 3.0 mpbs DSL from AT&T. We've been satisfied so far. However, someone has proposed service which includes a T1 line at 1.5 mbps. To me this sounds like a step down.

However, I took one of our laptops to one of her customer's and tested the connection via wireless G (could not get to the direct connection at the time). I ran three connections tests from through servers on this side of the country and got the following averages: Latency 70ms, Upload 732 Kbp/s, Download 1139 Kbp/s.

Then I checked our DSL wireless router (also 802.11g), ran the same three tests with these results: Latency 98 ms, Upload 280 Kbp/s, Dowload 512 Kbp/s.

We also have a 802.11n router connected via ethernet cable to the DSL router. I ran the same three tests again with these results: Lat 92 ms, Upload 285 Kbp/s, Download 1953 Kbp/s.

I think my next step should be to try to connect directly to the source and see. Or do the numbers above indicate that the T1 is actually going to be faster?

Any help or ideas?
