Abstract
A telephone network having a public announcement system is disclosed. Announcements are divided into message segments each of which is stored in a sector of a disc memory. When an announcement is activated, the message segments are loaded into a corresponding number of buffers for transmittal to calling customers. Each buffer will transmit the entire message, but in real time the buffers contain different message segments. Upon request for an announcement, the buffer containing the beginning message segment is selected to minimize holding time and customer waiting.
