Telephone line noise is an annoyance often associated with the use of a DSL Internet connection. The DSL modem sends and receives data at a higher frequency than that used by normal voice communication, fax machines or dial-up modems. While it does not prevent you from using your phone line for making calls while using the Internet as with traditional dial-up technology, it may produce an audible noise during telephone conversations. This noise may be eliminated through the use of phone line filters. Writer Bio
