General Information

This is DSL for the home user. This technology will enable faster data transmission through standard copper telephone lines. It is capable of accomplishing this through utilizing frequencies within the telephone cables that the human ear cannot hear. this allows for you to use your phone at the same time. This signal is unable to travel very far over standard telephone cables, typically under 5 km.


ADSL Technology

The distinctive characteristic that ADSL holds over other forms of DSL amount of data transmission is much greater in one direction than the other, hence the asymmetric. Providers commonly market ADSL as a  service for customers to connect to a high speed internet at relatively low cost.

There's both marketing and technical explanations why ADSL is the most popular type offered to home users. On the technical side, there is more commonly more crosstalk from other circuit devices at the DSLAM (Digital subscriber line access multiplexer) end of the circuit than at the customer's residents. This causes the upload signal to be at the weakest part of the local loop, and the download signal to be at the strongest part of the local loop. Therefore it makes more technical sense to have the DSLAM transmit at a much higher bit rate then the modem on the customers end. The typical customer does in fact prefer a faster download, then upload speed.
