Smarttnet - Support > ADSL FAQ

ADSL (Asymmetric Digital Subscriber Line) is a more efficient method of using traditional telephone cabling to transmit and receive information. The transmission of such information is done digitally as opposed to analogue as in the case of older data or fax modems. The modems are called asymmetric because they transmit data at a different speed than they receive. Please have a look at the following ADSL FAQ for more information.

1. How does ADSL work?

To receive ADSL service, two ADSL modems are required, one on either end of a telephone line. One modem is located in your home, while the second modem is in the nearest telephone central office. These modems are permanently connected to provide "always on" high-speed Internet access. The modems digitally divide your telephone line into 3 separate "channels" that separately handle your standard telephone traffic as well as your upstream and downstream data communications.

We provide asymmetric modem technology for maximum high-speed performance. As people seldom upload the same volumes of data as they download, asymmetric modems provide a larger downstream channel that allows more bandwidth and faster transmission speeds without affecting the speed of upstream data. For example, when you click on a link to see a Web page, your computer sends only that "click" which is a relatively small amount of data. In return, your computer receives a much larger volume of data when the page loads. Expanding the downstream bandwidth enhances speed and performance.

ADSL provides downstream data transmission rates 50 to 150 times faster than a dial-up modem Please note that the exact data transmission rates depend on the length of your phone line to a telephone Central Office.

2. Will my ADSL connection interfere with my phone service?

No, ADSL will not interfere with your phone service; you are able to use both simultaneously. Regular voice conversations use less than one percent of a telephone line’s capacity. ADSL technology uses the remaining 99 percent to transmit information 50 to 150 times faster than a conventional 28.8 Kbps modem. ADSL technology takes advantage of the unused capacity by dividing a copper telephone line into hundreds of segments, each of which is large enough to carry one telephone call.

3. Will Smarttnet's ADSL service slow down when there are several customers using the service?

No, your ADSL connection is not shared with others. There are no line-ups or traffic jams with ADSL technology because each user has their own dedicated high-speed connection to SmarttNet. However, you may experience some variation in speed if you have more than one computer linked simultaneously to SmarttNet ADSL from your home or when accessing various web sites.

4. How does SmarttNet ADSL compare to existing cable modem services?

Unlike cable modem service that relies on a network shared by all cable subscribers, SmarttNet uses ADSL technology that provides an Internet connection through your telephone line providing you with a secure and dedicated network. Your SmarttNet ADSL connection also provides you with your own bandwidth. Therefore, performance is not degraded during peak hours. In contrast, cable modem networks are configured as contention networks that means each user’s data must compete for upstream and downstream bandwidth. In addition, SmarttNet ADSL service does not require you to subscribe to cable service.

5. Can I get this service on my business line?

Yes. There are four plans available for your business. For further details please refer to Managed ADSL.

6. Does SmarttNet ADSL work on all type of Telephone lines?

No, ADSL uses copper phone wires, if your phone lines use a fiber-optic connection ADSL will not work. Centrix, ISDN, or Inter-Connect lines are also incompatible with ADSL service. However, ADSL will work with your existing phone service and SmartTouch features as well as with most Enterphone systems (although an Enterphone may cause slight interruption in the data stream).

7. Can I use more than 1 computer at my home?

Yes, however, each PC will require an IP address. An alternative would be to install a Proxy device such as a Router or Fire Wall. SmarttNet provides managed Fire Wall Services, please call us or e-mail sales@smartt.com for more information.
