The receiving modem answered with its own dedicated frequencies so that the modems could “talk simultaneously.” The technical term for this kind of modem is asynchronous.

Even though most cable and DSL providers may give it’s customers a modem with Internet service, the subscriber could also decide to supply his / her own modem. Generally the Internet provider has a list of compatible modems available, however these lists are rarely exhaustive.
