ABSTRACT:
There is disclosed a call announcement circuit integrated into the switching network of a PBX switching system such that the announcement board resides in one of the port slots and has direct access to the internal system buses. The circuit can handle many separate announcements each stored at a selectable compression ratio. Each such announcement can be recorded or played in any of the time slots under processor control. This configuration allows tradeoffs between storage capacity and compression ratio (i.e., speech clarity) and also allows messages to be played on any line or to any station via the communication bus and the selected time slot.
