Abstract: A digital intercept recorder/announcer system for use in conjunction with a telephone central office. The system performs the function of recorded message announcement for messages such as wrong number, time or weather announcements. The system samples and digitizes audio input signals from local or remote audio sources. Sampled data is stored in sequential fashion in memory so that it may be read out of memory exactly as it was stored. Upon demand, these stored signals are retrieved from memory, reconverted to an analog form and coupled to a subscriber's line for audio transmission to the subscriber. Delta modulation techniques are employed in the system.
