This category is for modems that use acoustic couplers for their connection to the phone line. This can either be a standalone modem, or terminals that have an integrated modem in their housing so as to provide dialup access to a computer. Most often this was done for portable terminals, but some desktop terminals also had integrated acoustic couplers.
