I have a Dell Dimension 2350 with a 56k PCI data/fax modem. Will this modem support DSL or do I need a separate modem?
DSL Basics
Digital Subscriber Lines (DSL) are a type of phone line that are often used for delivering high speed Internet access to homes and businesses. A single DSL line can handle two transmissions at once. For example, you can be connected to the Internet and make and receive phone calls on the same line. DSL service uses the same telephone lines as normal telephone service so you do not need to rewire your home in order to take advantage of the superior Internet speed offered. However, you will need a special DSL modem in order for your computer to interpret the data.
DSL Modems
If you have not yet ordered your DSL phone and Internet service, check with your telephone provider about a package deal. Many bundle the new DSL modem as part of the installation package. In addition, because DSL service degrades with distance from the phone utility’s central office, DSL service is not available in all areas. In general, you must be within about two miles of a central office.
Once you have DSL service and a DSL modem, you will need to connect your computer. Typically, the DSL line connects into an external DSL modem and then the modem connects to your computer via an Ethernet cable.
In addition, the computer will need to be set up with the appropriate ISP information. Many ISPs send a “self install” kit with the modem. These are relatively easy to use. You’ll be instructed in how to connect the computer to the modem and the modem to the DSL line. Once connected, you launch a CD and follow the prompts to set up your computer for using the service.
DSL Filters
DSL technology can interfere with other electrical equipment in your home. Because of this, your phone company will likely provide you with DSL filters. These plug into electrical outlets and allow your other equipment to run without interference.
Sharing DSL Internet Access
If you want to share your Internet access, you can connect your DSL modem to a router and create a small network. Read our DSL Sharing article for more information.
DSL modems start at about $25 and increase in price. Check with your DSL provider before buying a modem to make sure that it is compatible with the DSL service that you have subscribed to.
