Abstract:
A method for transmitting a facsimile from a first facsimile device to a second facsimile device over a network, said method being characterized by the steps of:negotiating by the first facsimile device via digital message protocols with the network a first proposed bandwidth for the digital transmission of data from the first facsimile device over a single digital channel to the second facsimile device; determining by the network via digital message protocols with the second facsimile device whether the first proposed bandwidth is acceptable to the second facsimile device; upon a determination that the first proposed bandwidth is acceptable to the second facsimile device, communicating from the network via digital message protocols to the first facsimile device that the first proposed bandwidth will constitute the negotiated bandwidth for the digital transmission of data from the first facsimile device over the single channel to the second facsimile device, and transmitting the facsimile from the first facsimile device via the single channel to the second facsimile device at substantially the negotiated bandwidth; upon a determination that the first proposed bandwidth is not acceptable to the second facsimile device, negotiating by the second facsimile device via digital message protocols with the network a second proposed bandwidth for the digital transmission of data from the first facsimile device over a single channel to the second facsimile device; determining by the network via digital message protocols with the first facsimile device whether the second proposed bandwidth is acceptable to the first facsimile device; and upon a determination that the second proposed bandwidth is acceptable to the first facsimile device, transmitting the facsimile from the first facsimile device via the single channel to the second facsimile device at substantially the negotiated bandwidth.
