Benefits of technology

[0012] Another advantage of the present invention is saving recording time by eliminating unnecessary verbiage within the speech files forming the calling service announcements. A further advantage of the present invention is increased speech file storage by the elimination of unnecessary speech files for unsupported calling service announcements.
[0013] Another advantage of the present invention is improved maintenance of the overall system due to the reduced number of components. Still another advantage of the present invention is the reduction of equipment necessary to implement multiple calling services, including a reduced number of circuit cards and maintenance trunk module slots.

Problems solved by technology

A telephone company seeking to implement a particular calling service must purchase all of the speech files, even though many of the fragments within the speech files do not support the desired calling feature.
Furthermore, due to limited memory space on the circuit cards, the resources of an entire circuit card can be exhausted in a typical implementation of a single calling service.

Embodiment Construction

[0017] Referring now to the drawings, FIG. 1 shows a known method of providing multiple calling service announcements such as for Automatic Call Back (ACB) and Enhanced Repeat Dial (ERD). Digital recorded announcement hardware consists of a speech processor, a microprocessor controller, and speech memory. Using Northern Telecom's equipment, for example, the prior art implementation of more than one calling service, such as ACB and ERD, required a 1×75AA / BA controller card 10 and four additional EPROM cards 12. A NT1×80AA EDRAM card 20 was also required because of the multi-tracked ERD announcement. The EPROM cards 12 contain speech memory comprising various phrases, tones, and periods of silence that are used to create a complete announcement. The controller card 10 can be programmed to select and retrieve the various phrases, tones and periods of silence from the speech memory of the EPROM cards.

[0018] The controller card 10, EPROM cards 12, and EDRAM card 20 each occupy a slot in...

Abstract

A method for providing multiple calling service announcements on a single circuit card within a telephone network. The method reduces the number of stored speech files necessary to generate announcements regarding a calling service such as Automatic Call Back or Enhanced Repeat Dial. By reducing the amount of speech data stored on a circuit card, multiple calling service announcements can be provided on a single circuit card, thereby reducing equipment costs.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a Continuation of U.S. patent application Ser. No. 09 / 104,552 filed on Jun. 25, 1998.TECHNICAL FIELD [0002] The present invention relates to telephone communication systems and particularly to automatic announcement systems adapted to be connected to telephone lines to provide for such services as Automatic Call Back and Enhanced Repeat Dial. BACKGROUND OF THE INVENTION [0003] Various services have become available with the development of communications technology. For example, in a telephone system, there are many services in practical use such as call forwarding, Automatic Voice Messaging (AVM), Automatic Call Back (ACB), Enhanced Repeat Dial (ERP), and Abbreviated Dialing (AD). These services are typically presented to users by recorded announcements. Recorded announcements for such calling services are formed from spoken words, phrases, tones or periods of silence stored in separate speech files. In response to a request for...
