5. Both residential and businesses properties around the world are already running out of spare lines on
existing installed telephone cables. ADSL provides service providers with the capability to use one line
to provide new data services while maintaining the telephone service on the same line, thus leveraging
the existing infrastructure.
6. ADSL provides telcos with the ability to offer a private, secure channel of communications between
the consumer and the service provider:
7. Data travels along the customers own line, unlike cable telephone and modem services where the line is
shared with others
8. Because it is one customer's dedicated line, transmission speeds are not affected by other users going
on-line. With cable modems, transmission speeds do drop significantly as more users go on-line
9. ADSL is "always on" and connected - just like a standard telephone. There is no time wasted dialing up
the service several times a day and waiting to be connected - ADSL is on standby, waiting ready for
use whenever your customer is ready.
10. Every major service provider has conducted trials and proven that the technology works. Today,
service providers are rolling out ADSL services worldwide, with widespread deployment expected. In
support of this market, a large number of major equipment vendors are shipping second and third-
generation products offering higher performance and lower cost.
11. ADSL-based networks are well suited for carrying ATM traffic, thus future- proofing ADSL
technology for decades to come.
12. ADSL provides the communication bridge into the next century, without added new infrastructure,
costly outside plant additions and reinvestment.
Advantages to the End User
1. ADSL transforms plain old telephone lines into a high speed conduit for data, information,
entertainment and more. And while it is doing that, you can still use your telephone for normal
conversations at the same time. That provides enormous advantages whether at home or at work.
2. ADSL provides affordable high-speed remote access to the Internet, corporate networks and on-line
services over ordinary phone lines.
