over the fixed line a modem is needed on each end of the line. The modem takes the digital information and turns it into tones that have been specifically selected for the transmission over telephone network. The modem at the other end is responsible for turning the tones back into digital data. Data rates were limited until digital subscriber line (DSL) was introduced. DSL used the existing analog phone line so there was no need for new equipment other than modems that convert digital data
