Abstract: In a communication complex having attendant positions and data terminals, the audio equipment of each position can be associated with the data terminals without direct connections between the switching system which drives the audio equipment and the host computer which drives the terminals. A programmed controlled call processor communicates between the switching system and the host computer and maintains a correlation between the audio equipment and the data terminals. In response to incoming calls, the call processor solicits from an attendant identification information and then accesses a look-up table with such information to find a data terminal associated therewith. Data terminal identification information is coupled to the host computer so that data can be transmitted and displayed on the terminal associated with the attendant responding to the incoming call.
