Abstract

Communication system, particularly a telephone communication system. The communication system has a controller (CC, CVSM) and a first central memory (SP, RAM) that accepts messages, particularly voice messages. Instead of a separate tone means that forms user prompting/alerting tone signals and/or control information signals for message exchange protocols, the first central memory (SP, RAM) forms the tone means and contains stored alerting tone signals and/or control information signals for message exchange protocols.

Claims

1. A communication system having at least one controller with at least one first central memory for storing communicated messages, the communication system also having at least one of internal terminal equipment, of at least one connection to external terminal equipment and of at least one connection to central equipment of another communication system, comprising:

tone means that forms at least one of user prompting/alerting tone signals and control information signals for message exchange protocols that the controller calls in from the tone means for transmission to the at least one of the internal terminal equipment of the communication system, the external terminal equipment and the central equipment of another communication system, the tone means being formed in the at least one first central memory that stores at least one of the alerting tone signals and control information signals for message exchange protocols, the tone signals and control information signals being stored in the first central memory along with the messages and being called in by the controller in the same manner as the messages are called in by the controller.

2. The communication system according to claim 1, wherein the messages stored in the at least one first central memory are stored in compressed form and wherein the at least one of the alerting tone signals and control information signals for message exchange protocols stored in the at least one first central memory are stored in non-compressed form.

3. The communication system according to claim 1, wherein the at least one controller of the communication system has a second central memory allocated to it that forms an audio tone means and in which signals representing audio tones are stored.

4. The communication system according to claim 1, wherein the audio tones include at least one of calling tones, busy signals, special tones and special call tones.

5. The communication system according to claim 1, wherein the messages are voice messages and the communication system is a telephone communication system.

6. A telephone communication system comprising at least a first controller with a first central memory for storing communicated voice messages, the communication system having at least one of internal terminal equipment, of at least one connection to external terminal equipment and of at least one connection to central equipment of another communication system;

a tone means that forms at least one of user prompting/alerting tone signals and control information signals for message exchange protocols that the first controller calls in from the tone means for transmission to the at least one of the internal terminal equipment of the communication system, the external terminal equipment and the central equipment of another communication system, the tone means being formed in the first central memory that stores at least one of the alerting tone signals and control information signals for message exchange protocol, which are stored in the first central memory in the same manner as the voice messages and which are called in by the first controller in the same manner as the voice messages are called in by the first controller.

7. The communication system according to claim 6, wherein the messages stored in the first central memory are stored in compressed form and wherein the at least one of the alerting tone signals and control information signals for message exchange protocols stored in the first central memory are stored in non-compressed form.

8. The communication system according to claim 6, wherein the communication system has a second controller with a second central memory, the second central memory being an audio tone means in which signals representing audio tones are stored.

9. The communication system according to claim 8, wherein the audio tones include at least one of internal calling tones, busy signals, special tones and special call tones.

10. A telephone communication system comprising:

a first controller with a first central memory for storing communicated voice messages, the communication system having at least one of internal terminal equipment, of at least one connection to external terminal equipment and of at least one connection to central equipment of another communication system;

a tone means that forms at least one of user prompting/alerting tone signals and control information signals for message exchange protocols that the first controller calls in from the tone means for transmission to the at least one of the internal terminal equipment of the communication system, the external terminal equipment and the central equipment of another communication system, the tone means being formed in the first central memory that stores at least one of the alerting tone signals and control information signals for message exchange protocols, the tone signals and control information signals being stored in the first central memory along with the messages and being called in by the controller in the same manner as the messages are called in by the controller;

the messages stored in the first central memory being stored in compressed form and the at least one of the alerting tone signals and control information signals for message exchange protocols stored in the first central memory being stored in non-compressed form; and

a second controller with a second central memory, the second control memory being an audio tone means in which signals representing audio tones are stored.

11. The communication system according to claim 10, wherein the audio tones include at least one of internal calling tones, busy signals, special tones and special call tones.
