Abstract (en)
[origin: CA1336840C] A real time automated interactive mass communications system provides communications between a central communications processor and groups of subscribers. Typically, each group is associated with a central office. A set of local communication processors are provided, each being in two-way communication with the central processor and each being linked to one of the central offices and being preferably on site. Each local communication processor includes a processor unit, an audio controller and a set of multi-line controllers. The audio controller takes audio messages received from the central processor and generates a train or delayed set of the messages which are supplied to each of the multi-line controllers. Each multi-line controller services a set of lines connected to the central office switch, receives telephone number data from the central communication processor, and calls the list of telephone numbers to which it has been assigned. Upon detecting a subscriber response, the multi-line controller selects the next occurring message in the message train for transmission to the subscriber. Subscriber responses in the form of key depressions are detected in the multi-line controllers and are used to supply data relating to the subscriber response to the central communications processor.
