ABSTRACT:
A coin telephone message and management system is provided for use at a central office location of a telephone system with a plurality of conventional remotely located coin telephone stations and with, or in place of, an automated coin subsystem to which the coin telephone stations are otherwise connected by coin trunks. The coin telephone message and management system comprises a plurality of programmable line interface units each being connected to a said coin trunk for monitoring electrical signals present on the coin trunk indicative of usage of the station connected thereto, for delivering predetermined messages to a user of the station, and for generating electrical signals emulative of operation of the station for thereby controlling the automated coin subsystem; a message storage and delivery unit selectively connectable to the programmable line interface units for delivering at least one selectable audio message to the user of a said station via the coin trunk; and, a programmed system controller for coordinating operations of the programmable line interface units and the message storage and delivery unit for delivery of selected messages to the user of a said station, for responding to data entered by the user of a said station and for causing electrical signals emulative of operation of the station to be generated by the line interface unit.
