ABSTRACT:
A plurality of magnetic tape cassettes each has a prerecorded message, and the messages are simultaneously communicated to telephone subscribers by apparatus which incorporates a corresponding plurality of tape decks. The telephone lines and tape decks are independently coupled together by corresponding tape subsystems each having a control system which is activated after a telephone connection has been established. After each tape subsystem completes its message transmission, it releases itself from the corresponding telephone line, and provides an indication that it is again available to be accessed. After all of the prerecorded messages on each tape are transmitted, the tape cassette automatically rewinds.
