초록 ▼

A data interface for use in a communication system, comprised of a CPU module connected to a central controller of the communication system and a plurality of data terminals associated with respective subscriber sets of the communication system. The CPU module communicates with the central controller in response to user initiated requests at the respective data terminals, and executes telephone special features in association with the respective sets, such as dial-by-name, etc. The CPU module can also be connected to a personal computer, for interfacing the data terminals therewith on a time sharing basis. Furthermore, the CPU module functions as a data switch for implmenting electronic mail between the data terminals within the communication system. A communications module incorporating modems and TelexTMinterfaces can be connected to the CPU module for establishing communication between the data terminals and one or more outside telephone lines via the communication system.

대표청구항 ▼

In a communication system connecting to outside lines and comprised of local subscriber ports and a central controller for interconnecting predetermined ones of said ports and said lines; a data interface comprised of at least one data terminal which is associated with a corresponding at least one port for generating digital command signals designating predetermined special features, and a CPU module connected to said central controller and interfacing said at least one data terminal, for receiving and interpreting said digital command signals from said at least one data terminal and in response initiating execution by said central controller of said predetermined special features.
