| titleOfInvention | Tone and announcement message code generator for a telephonic switching system and method |
| abstract | A tone and announcement PCM code generator (10) outputs to selected multiple channels of a TDM telephonic switching system (12) selected tones and voice announcements stored in a message memory (16) according to command signals from a telephonic switching system central controller (12A) through a share memory (20) to a state machine, or sequencer, (22). The sequencer controls the message memory (16) to provide selected tones and voice announcements through a serial interface (24) on the selected TDM channels. The entire repertoire of tones and announcements can be down loaded from a central memory (12B) of the telephonic switching system (12), and customer designed voice messages from any channel of the telephonic switching system can be stored in the message memory (16) for later local playback or for up loading to the central memory (12B). All tones and announcements are processed uniformly and any tone or announcement can be preselected to any or all channels simultaneously for maximum system flexibility. The entire period of periodic tone signals including the silent segment are stored to enable processing in the same way as continuous tones. |
