A Simple Explanation Of A DS3 Line (aka DS3 Bandwidth)

To the point .... a DS3 line is an ultra high-speed connection capable of transmitting data at rates up to 45 Mbps. A DS3 line is equal to approximately 672 regular voice-grade telephone lines, which is fast enough to transmit full-motion, real-time video, and very large databases over a busy network.

Hopefully you are aware of what a T1 is .... now assume that a T1 is like a two-lane highway.

Next .... consider this simple analogy for a DS3 line:

* Full DS3 -

A highway that has 28 times the number of lanes that a T1 highway has. All these lanes are free to be used by your business .... and is also the reason you pay more than for a T1. However, you must be doubly sure that you need such a wide highway to justify the cost. Do also consider that this cost has been dropping drastically in the last few years so it is much easier to justify today.

* Fractional DS3 -

You have a highway that has 28 times the number of lanes that a T1 highway has. However, because you don't need such a wide highway, you are being charged for only 3-10 times the T1 highway. If you need more T1 lanes to be used, you must pay. If that happens the DS3 line provider will remove the necessary roadblocks in very little time.

* Burstable DS3 -

You have unlimited lanes on a highway you've built. You 28 T1 highways reserved for you to use. If you need more T1 highways, your provider may make them available subject to availability and won't charge you for it. But if you keep asking for free T1 highways on a regular basis, the provider will have to say NO and you will have to buy more T1 highways.

* Point-to-Point DS3 -

You have 28 T1 highways reserved for traffic .... only for you .... to travel between points A and B. You cannot exit the highway at any point other than the destination.

I think you have missed the some of the important points of a DS3. A DS3 is can be delivered as a straight 45 Mbps dedicated data pipe, not just bonded T1s. DS3s have a greater response than T1s
Ethernet is a shared resource with less security. A need for 6 to 8 T1s will justify a DS3.
