DSL Modem

If you don't have a direct DSL line built into your wall (as is usually the case with older homes) you need to connect your DSL modem to a phone line. However, if you are using two different DSL modems in the same room you need to plug the two different DSL modems into the same phone line. This is possible through the aid of a filter and a splitter.
