SDSL vs T1 ... Which Is The Best Bandwidth Solution For YOUR Business?

SDSL or T1 bandwidth .... which would you choose as the bandwidth solution backbone for your business? Good question ... often asked ... and the answer is NOT as complicated as many make it out to be.

There are many differences:

1. DSL is distance sensitive to the CO (Carrier Office). T-1 lines are not.

2. DSL is a shared connection. A T-1 is a dedicated connection.

3. DSL is typically oversubscribed by your phone company. The best way I can think to describe it is that there are more users than there is available bandwidth. The phone company counts on the fact that everyone won't be using the bandwidth at the same time. You may notice slowdowns during peak times.

4. T-1s typically have lower latency.

5. T-1s typically have better SLAs (Service Level Agreements).

6. If your T-1 line goes down, it will typically be guaranteed to be repaired much faster than your DSL line.

7. Many DSL providers have bandwidth caps. Your T-1 bandwidth is yours.

Those are just a few that come to mind ... there are others but I wanted to focus you on the basics.

I think the key difference between SDSL and T1 is the circuit between your location and the carrier office.

A T1 circuit will be a specially engineered data circuit specially conditioned for digital data and it has to be designed by the LEC (Local Exchange Carrier) from POP (Point Of Presence) to premise.

SDSL uses a voice grade equivalent analog circuit, which is why it's less expensive and quicker to install -- no special engineering required. This leads to some consequences especially when there is a problem: an analog circuit is not a priority for restoration efforts, whereas a T1 is a top priority for restoration. Don't take my word for it. Just ask your carrier about the difference for mean time to repair for both SDSL and T1.

If you're putting this into your home so your geeky kid can play WoW then the repair time won't be such a big deal .... compared to if you are running a business and you're employees and customers don't expect any downtime.

Bottom line is if you believe your business functions are critical .... than a T1 is a must.

For help in finding the right T1 based business bandwidth solution for you .... I suggest using the no cost support available here: T1 Bandwidth
