Abstract
A central processing system interfaces remote terminals through a dial-up telephone facility to complete various communication formats selectively involving either an audio response unit (ARU) or a telecommunications service representative station (TSR station). A substantial number of ARU's accommodate many calls simultaneously, executing formats whereby a caller is given voice cues or prompts to input digital data using the telephone keypad. Similarly, a substantial number of TSR stations accommodate calls in various formats with a prompting data display. Calls are selectively allocated to an ARU or a TSR station on the basis of time, call loads and call format. A programmable logic array cooperates with a host computer, load indicators and a clock (time class indicator) to implement a program of call allocation. Accordingly, the structure and process accommodate multiple-port, multiple-format operation.
