Abstract

A method is disclosed for transmitting information from a non-ISDN compatible communication device to an ISDN compatible receiving device via the D Channel of an Integrated Systems Digital Network. To facilitate this transmission, the information is reformatted, embedded in an ISDN signaling protocol message, and transmitted to an ISDN compatible recipient as Message Associated User-To-User Information.

Claims

1. A method for the transmission of message associated user-to-user information comprising the steps of:

receiving a user generated analog signal containing message related information from a non-ISDN compatible communication channel within a switched telecommunication system;

transforming said received signal into digital data suitable for data processing;

processing the digital data so as to extract message related information;

embedding said extracted message related information within an ISDN compatible signaling protocol message; and

transmitting said ISDN compatible signaling protocol message to a specific ISDN recipient via a D Channel within a switched telecommunication system.

2. The method of transmitting message associated user-to-user information of claim 1 wherein the received user generated analog signal containing message related information is a signal representing an image transmitted by a facsimile transmitter.

3. The method of transmitting message associated user-to-user information of claim 1 wherein the received user generated analog signal containing message related information is a signal representing digital data encoded and transmitted by a modem.

4. The method of transmitting message associated user-to-user information of claim 1 wherein the received user generated analog signal containing message related information is a signal representing digital data encoded and transmitted by a modem.

5. A method for the transmission of message associated user-to-user information comprising the steps of:

receiving a user generated analog signal containing message related and recipient related information via a non-ISDN compatible communication channel within a switched telecommunication system;

transforming said received signal into digital data suitable for data processing;

processing the digital data so as to extract message related and recipient related information;

selectively retrieving destination data from a data storage means in response to said extracted recipient related information;

embedding said extracted message related information within an ISDN compatible signaling protocol message; and

transmitting said ISDN compatible signaling protocol message to a specific ISDN compatible receiving means via a D Channel within a switched telecommunication system, said receiving means being selected as a function of said retrieved destination data.

6. The method of transmitting message associated user-to-user information of claim 5 wherein the received user generated analog signal containing message related and recipient related information is a signal representing human speech.

7. The method of transmitting message associated user-to-user information of claim 5 wherein the received user generated analog signal containing message related and recipient related information is a signal representing an image transmitted by a facsimile transmitter.

8. The method of transmitting message associated user-to-user information of claim 5 wherein the received user generated analog signal containing message related and recipient related information is a signal representing digital data encoded and transmitted by a modem.

9. A method for the transmission of message associated user-to-user information comprising the steps of:

receiving a user generated analog signal containing message related information via a non-ISDN compatible communication channel within a switched telecommunication system;

transforming said received signal into digital data suitable for data processing;

processing the digital data so as to extract message related information;

selectively retrieving destination data from a data storage means as a function of the particular non-ISDN compatible communication channel upon which the signal containing message related information was received;

embedding said extracted message related information within an ISDN compatible signaling protocol message; and

transmitting said ISDN compatible signaling protocol message to a specific ISDN compatible receiving means via a D Channel within a switched telecommunication system, said receiving means being selected as a function of said retrieved destination data.

10. The method of transmitting message associated user-to-user information of claim 9 wherein the received user generated analog signal containing message related information is a signal representing human speech.

11. The method of transmitting message associated user-to-user information of claim 9 wherein the received user generated analog signal containing message related information is a signal representing an image transmitted by a facsimile transmitter.

12. The method of transmitting message associated user-to-user information of claim 9 wherein the received user generated analog signal containing message related information is a signal representing digital data encoded and transmitted by a modem.
