The Meridian Communications Adapter (MCA) allows computers and other devices to communicate easily through the telephone network. By adding this cartridge to Meridian Digital Telephones, personal computers, ASCII terminals, video equipment and group IV fax machines can communicate via the built-in RS-232 or v.35 interface. This uses the standard telephone wiring already in place and eliminates the need for dedicated data facilities.
