Abstract
Abstract An integrated communication system for the transception of facsimile data or binary file data is described. The system comprises a conventional facsimile machine having the components of a scanner, sampling device, transmission memory, compression device and modem connected to a telephone line of a public switched telephone network all being for the transmission of facsimile data and decompression device, reception memory, recording memory and recording device all being for the reception of facsimile data. These components are under the control of the operations microprocessor and user interface. The binary file data transfer components are the Tx/Rx memory, floppy disk controller and floppy disk drive, again, all under the control of the operations microprocessor. The binary file transfer is achieved either by control codes inserted in the Non Standard Filed (NSF) of a facsimile transmission conducted under the CCITT Recommendation T.30, or the proposed amendments to the DIS/DTC/DCS signals of the same T.30 Recommendation as are under consideration.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
215 words
An integrated communications system using facsimile communication protocols comprising: a facsimile transceiver and a binary file data transceiver connected to a communications channel so that both said transceivers are either at a source origination or at a target destination, processor means interconnecting said binary file data transceiver with said facsimile transceiver, said processing means controllable during one continuous session, a.) as a target destination, to look for control signals in a frame of an incoming transmission on the communications channel to determine if the transmission is a facsimile or binary data file and to switch said facsimile transceiver to receive the transmission if it is signalled as a facsimile transmission and, to switch said binary data file transceiver to receive the transmission if it is signalled as binary file data and, to continue to look for control signals in a frame of the transmission signalling a change from facsimile transmission or binary file data transmission and to switch the facsimile transceiver or binary file data transceiver as appropriate to then receive the transmission, and b.) as a source origination, to insert control signals in a frame of an outgoing transmission to signal whether the transmission is facsimile or binary file data, whereby both facsimile and binary file data can be transceived using facsimile communication protocols.
Claim 2
Dependent Claim
215 words
An integrated communications system using facsimile communication protocols comprising: a facsimile transceiver and a binary file data transceiver connected to a communications channel so that both said transceivers are either at a source origination or at a target destination, processor means interconnecting said binary file data transceiver with said facsimile transceiver, said processing means controllable during one continuous session, a.) as a target destination, to look for control signals in a frame of an incoming transmission on the communications channel to determine if the transmission is a facsimile or binary data file and to switch said facsimile transceiver to receive the transmission if it is signalled as a facsimile transmission and, to switch said binary data file transceiver to receive the transmission if it is signalled as binary file data and, to continue to look for control signals in a frame of the transmission signalling a change from facsimile transmission or binary file data transmission and to switch the facsimile transceiver or binary file data transceiver as appropriate to then receive the transmission, and b.) as a source origination, to insert control signals in a frame of an outgoing transmission to signal whether the transmission is facsimile or binary file data, whereby both facsimile and binary file data can be transceived using facsimile communication protocols.
Claim 3
Dependent Claim
29 words
A system as claimed in claim 1, wherein said binary file data is sourced from or targeted to mass data storage means contained with the binary file data transceiver.
Claim 4
Dependent Claim
37 words
A system as claimed in claim 1, wherein said control signals are inserted in the Non Standard Frame of a facsimile transmission conducted under the CCITT T.30 Recommendation or the DIS/DTC/DCS signals of the CCITT T.30 proposals.
Claim 5
Dependent Claim
134 words
A facsimile machine for the transmission of documents on a communications channel, said facsimile machine being operable to provide facsimile transmission or binary file data transmission in the one continuous session and further comprising: data storage means for storing a binary file data, and processing means which is controllable to insert control signals in a frame of an outgoing transmission to signal if the transmission is facsimile or binary file data and to transmit either the facsimile or binary file date from said data storage means, whereby both facsimile and binary file data can be transmitted using facsimile communication protocols, and wherein said control signals are inserted in the Non Standard Frame of a facsimile transmission conducted under the CCITT T.30 Recommendation or the DIS/DTC/DCS or modified DIS/DTC/DCS signals of the CCITT T.30 Proposals.
