KEY TELEPHONE SYSTEM AND MAIN UNIT THEREOF

摘要

A soft key template table and a data template table are stored in both of a storage section of a main unit and a storage section of a voice mail server. The soft key template table and data template table are databases in which guidance messages to be displayed on a display of each key telephone are associated with corresponding numbers. Code information including template numbers is transmitted over a serial line. A conversion processing section converts the template number to a display message and causes the display to display the message.
