Many high speed Internet users are still in the dark about an inexpensive connection that is faster than the commonly used Asymmetrical Digital Service Line (ADSL), cable, or even fiber lines.
Another kind of DSL called Symmetrical Digital Service Line (SDSL) is fairly unknown to those that are not the most Internet-savvy, however, it can be used to transmit and receive large chunks of data at higher speeds. SDSL can receive or transmit up to 3 megabits per second whereas ADSL can receive data at a rate of 1.5 Mbps and can only send data at a rate of 16 to 640 kilobits per second.
Other benefits of SDSL include the lack of equipment required to set it up as it does not require either an optical or coaxial cable network. Instead it uses the standard twisted-pair copper wires that land-line telephones use. And although some Internet users may not know about SDSL, the service is now available in many areas and is turning into an affordable alternative to more expensive forms of high speed Internet.
SDSL is suitable for small or medium sized business, but consumers that need an inexpensive way to achieve high bandwidth may find SDSL the perfect solution for homes as well. For example, people that use many Internet applications that require large volumes of data to be sent or received, such as voice over Internet protocol (VoIP), advanced computer gaming, video conferencing or live webcasting may find that because SDSL supports high speed data transfers – both for receiving and sending – it is superior to other forms of Internet for only a slight increase in cost.
For an SDSL connection a special modem is required which connects the telephone line to a router or directly to a computer. This modem converts the digital signals from the telephone and exchanges them into a format which the computer is then able to understand. The modem can be rented or purchased depending on the consumer’s needs.
An SDSL connection has many benefits over its cousin, the ADSL connection and for many businesses it may soon be replacing ADSL because of its ability to transfer such large chunks of data for only a slight increase in price.
