Congratulations on your decision to begin using DSL. DSL is a relatively new broadband technology that carries data signals up to 20 times faster than 56K dial-up modems on the high-frequency portions of phone lines, which also transmit voice signals. But DSL users don't dial a phone number to log on to the Net like with dial-up services. Rather, as with cable-modem services, a DSL line is continuously open. DSL uses two modems, one at the customer end and one at the phone company (called a DSLAN), which communicate constantly with each other.
Digital Subscriber Line (DSL) is dramatically faster than the 28,800 or 56k modems you've been using. You'll probably drop your jaw in surprise when you actually see the difference. You will NEVER want to go back to your old modem. You only need one phone line and you can talk AND surf on it at the same time!
DSL or Digital Subscriber Line allows for Internet speeds approaching that of T-1 lines, but delivered over standard phone lines! Compare the speeds below. Your 56k modem, (56 Kbps) is twice as slow as even a slow DSL speed of 144Kbps. Look below!
- IDSL
- ISDN over DSL; the speed is 144 Kbps Upstream and Downstream.
- SDSL
- Symmetrical DSL; the speed is the same Upstream and Downstream with speed choices of 192 Kbps, 384 Kbps, 768 Kbps and 1.1 Mbps.
- ADSL
- Assymmetrical DSL; the speed is lower Upstream and higher Downstream with speed choices of 64 Kbps/256 Kbps, 384 Kbps/1.5 Mbps and 768 Kbps/1.5 Mbps.
Surf the internet at 50 times faster than standard dial-up! No phone line needed!
