The T3 line is very flexible. It can be used for both voice and data at the same time via channels. A portion of the line would be dedicated to voice communications while the rest of it is used for data. There can be cost savings by using the T3 line for multiple uses since the dedicated line only needs to be brought in only once. So when getting a T3 Line Price Quote, it's important to consider the savings that would occur if voice goes over the T3 instead of separate phone lines.
The dedicated download and upload speed of a T3 is very high and much better than DSL or cable, which have key disadvantages for business users. First of all, the upload speed is usually severely limited with low-end DSL and cable Internet products. That makes them inappropriate for running a web server of any kind, especially one that has video content. Secondly, the bandwidth is not dedicated. That means downloads or uploads can be very slow during the peak hours of the early evening. If the neighborhood is oversubscribed with too many cable or DSL customers, there will be slowdowns and timeouts as well. The dedicated high speed of T3 avoids all of these issues.
Generally, businesses with high bandwidth or voice service needs are the ones that will need to get a T3 Line Price Quote. The private T3 line can produce a lot of savings over other products as well as very high quality voice and data services that businesses need and expect.
