There are two major differences:

Speed. A T1 operates at 1.544 Mb/s in both directions. It is also referred to as a symmetrical circuit because the speed is always identical on the upload and download side. DSL has varying speeds. In almost all cases the download is two to ten times faster than the upload speed. It is usually classified as an asymmetrical circuit.

Reliability. When you purchase a T1 from any carrier, they are required to place a physical T1 repeater (similar to an amplifier) on the physical line every 6,000 feet from the telephone office. They can do this to extend a T1 as physically far as necessary, but if you go to far, this can be cost prohibitive. The repeaters guarantee the T1 signal. In contrast, DSL lines do not have repeaters. They are plain copper from the telephone office to your home or office. A DSL line is typically limited to an 18,000 foot distance from the telephone office.

When should I purchase a DSL line?

If you are mostly downloading, DSL is the right technology for your home or office. If you plan on operating a web server or e-mail server, definitely look at other technologies.

We offer Business class DSL services in 53 major cities in the U.S. starting at $69.95 per month. Our speeds available go as high as 15Mb/s depending on your city and distance from the telephone office.

To get started, please call 866-905-8174 or e-mail info@dhk.com.

When should I buy a T1?

It's time to get a T1 when you are installing a web server, e-mail server, or VoIP at your office. In all of these cases, the upload speed and reliability of the T1 is critical to their successful operation.

Depending on availability, we offer business T1 solutions starting at $369 per month.

To get started, please call 866-905-8174 or e-mail info@dhk.com.

When should I buy a Bonded T1?

Bonded T1s offer the reliability of T1 circuits with increased speed. The "bonding" of T1s together happens at your router. Very simply put, in order to get more bandwidth with T1 technology, the router can make more T1s operate like 1 circuit.

To get 3.0 Mb/s, add two T1s together.
To get 4.5 Mb/s, add three T1s together.
To get 6.0 Mb/s, add four T1s together.

We currently offer 3.0Mb/s dual bonded T1s at a rate of $699 per month (depending on availability).

To get started, please call 866-905-8174 or e-mail info@dhk.com.

Faster Circuits: T3 / OC-3 / OC-12 / more...

When your company is in need of some serious Internet speeds of 45Mb/s and higher, we can solicit for pricing offers from multiple carriers. In some cities there may be cost effective Metro Ethernet solutions.

In most cases, there is significant lead time to install these circuits. Please call as soon as you are in the planning stages so that we can make sure that the deadlines are met.
