Abstract

In a telecommunications system 10 in which remote terminals 20A through 20G are exchanging information with Interactive Information Response Unit (IIRU) 30 via communications in diverse formats and/or media, a system and method for identifying said formats and/or media so that responsive to said identification, appropriate resources 33 may be allocated to the communications to enable IIRU 30 and remote terminals 20A through 20G to exchange information intelligibly.

5. The method of claim 1, in which said actual format determining step comprises the steps of:

detecting modem handshake signals received from the remote terminal, and determining whether the source of said modem handshake signals is a fax modem or a data modem or a hearing impaired modem.

6. The method of claim 5, in which said modem is coupled to said system by an interconnecting link, and in which said actual format determining step further includes the substep of:

establishing the data transfer speed and bandwidth capabilities of said data modem in combination with said interconnecting link.

7. The method of claim 1, in which said actual format determining step comprises the steps of:

detecting modem handshake signals received from the remote terminal, and recognizing that the source of said modem handshake signals is a data modem, and in which said method further comprises the step of;

determining whether the remote terminal will support communications in one or more predetermined media.

8. The method of claim 7, in which said actual format determining step is accomplished by robotically polling the remote terminal.

9. The method of claim 7, in which said actual format determining step is accomplished by requesting a user of the remote terminal to identify media that are supported.

10. The method of claim 7, in which said one or more predetermined media are selected from the group consisting of:

(a) text;

(b) MIDI sound;

(c) WAV sound;

(d) graphics; and

(e) video.

11. The method of claim 1, further comprising the step of selectively using compression algorithms in exchanging said information.

12. The method of claim 11, in which said compression algorithms are not used when the data transmission rate at which information may be exchanged exceeds preselected levels.

13. The method of claim 1, in which said actual format determining step includes the substep of recognizing that the communication is in digital format, and in which said method further comprises the step of:

determining whether the remote terminal will support communications in one or more predetermined media.

14. The method of claim 13, in which said actual format determining step is accomplished by robotically polling the remote terminal.

15. The method of claim 13, in which said actual format determining step is accomplished by requesting a user of the remote terminal to identify media that are supported.

16. The method of claim 13, in which said one or more predetermined media are selected from the group consisting of:

(a) text;

(b) MIDI sound;

(c) WAV sound;

(d) graphics; and

(e) video.

17. The method of claim 1, in which said actual format determining step includes the substep of recognizing that the communication is in fax format and in which said method further comprises the steps of:

prevalidating the authority of the remote terminal to exchange information with said system; and

establishing whether a fax is to be sent or received by said system.

18. The method of claim 17, in which the step of prevalidating includes the substeps of:

identifying the remote terminal; and

matching said identity against prestored authorized remote terminal identities.

19. The method of claim 18, in which the substep of identifying includes reading the Automatic Number Identification (ANI) origin from which the remote terminal is communicating.

20. The method of claim 17, in which said establishing step is accomplished with reference to predetermined communication parameters.

21. The method of claim 20, in which said predetermined communication parameters include one or more parameters selected from the group consisting of:

(a) Automatic Number Identification (ANI) origin from which the remote terminal is communicating;

(b) Dialed Number Identification Service (DNIS) destination to which the remote terminal'"'"'s communication is incoming; and

(c) Polling mode signals in handshaking protocols between the remote terminal and said system.

22. A telecommunications system to which one or more remote terminals are coupled via interconnecting links to enable communications therebetween, said communications characterized by a plurality of separate data transmission requirements among said remote terminals and said interconnecting links, the telecommunications system comprising:

means for determining data transmission requirements for said remote terminals, wherein said data transmission requirements correspond in part to a particular type of communications device at said remote terminals;

database means for storing generic information that is to be transmitted by said telecommunications system;
