Claims
- 1. A first facsimile apparatus in a communication system on a data reception side thereof, the system comprising the first facsimile apparatus and a second facsimile apparatus each connected to an inside bus of an integrated services digital network, ISDN, said first facsimile apparatus comprising:
- means for monitoring a signal on the inside bus of the ISDN;
- means for determining whether or not the monitored signal is an announcement of interruption from the second facsimile apparatus on the bus; and
- means for performing substituting reception in place of the second facsimile apparatus when said determination means has determined that the signal is an announcement of interruption;
- wherein said announcement of interruption is a signal indicative of interruption of reception of data from the ISDN by the second facsimile apparatus output during the reception of the data from the ISDN, and
- wherein said performing means performs, in place of the second facsimile apparatus, the reception of the data, thus enabling reception of the data from the ISDN which was interrupted by the second facsimile apparatus,
- said first facsimile apparatus further comprising means for determining whether or not an abnormality has occurred in said first facsimile apparatus during the substituting reception, and means for issuing an announcement of interruption onto the bus when an abnormality has occurred.
- 2. A facsimile apparatus according to claim 1, wherein said monitor means monitors a D-channel signal on the inside bus.
- 3. A facsimile apparatus according to claim 1, wherein said determination means determines from the announcement of interruption that toner has been exhausted in the other facsimile apparatus.
- 4. A facsimile apparatus according to claim 1, wherein said determination means determines from the announcement of interruption that recording paper in the other facsimile apparatus has jammed.
- 5. A facsimile apparatus according to claim 1, wherein said determination means determines from the announcement of interruption that there has been a shortage of recording paper in the other facsimile apparatus.
- 6. A first facsimile apparatus in a communication system on a data reception side thereof, the system comprising the first facsimile apparatus and a second facsimile apparatus each connected to an inside bus of an integrated services digital network, ISDN, said first facsimile apparatus comprising:
- reception means for receiving an image transmitted via the ISDN;
- recording means for recording the image received by said reception means;
- determination means for determining whether or not trouble has occurred during the recording of the image by said recording means; and
- interrupting means for interrupting the reception of the image during the reception of the image from the ISDN when said determination means has determined the occurrence of trouble;
- said interrupting means issuing an announcement of interruption to said inside bus to enable the second facsimile apparatus on said inside bus to perform the reception of the image that was interrupted,
- said first facsimile apparatus further comprising a memory for storing the image and means for determining whether or not the memory overflows when trouble occurs, and wherein said first facsimile apparatus issues said announcement of interruption when the memory has overflowed, and performs reception by the memory when the memory has not overflowed.
- 7. A facsimile apparatus according to claim 6, wherein said determination means determines whether or not toner has exhausted in the recording means.
- 8. A facsimile apparatus according to claim 6, wherein said determination means determines whether or not jam of recording paper has occurred in the recording means.
- 9. A facsimile apparatus according to claim 6, wherein said determination means determines whether or not there is a shortage in recording paper in the recording means.
- 10. A facsimile apparatus according to claim 6, wherein said issuing means issues the announcement of interruption using a D-channel signal.
- 11. A facsimile system on a data reception side of a communication system comprising:
- first and second facsimile apparatuses connected to a bus of an ISDN;
- said first facsimile apparatus comprising:
- reception means for receiving an image signal;
- recording means for recording an image on recording paper according to said received image signal; and
- means for interrupting the reception of said image signal and for issuing an announcement of interruption when trouble has occurred in said recording means during recording of said image by said recording means;
- said second facsimile apparatus comprising:
- detection means for detecting the announcement of interruption issued onto said bus; and
- means for starting reception of said image signal when said detection means has detected the announcement of interruption, wherein the reception of said image signal was interrupted by the interrupting means of said first facsimile apparatus,
- wherein said first facsimile apparatus further includes a memory for storing the image and means for determining whether or not the memory overflows when trouble occurs, and wherein said first facsimile apparatus issues said announcement of interruption when the memory has overflowed, and performs reception by the memory when the memory has not overflowed.
- 12. A facsimile system according to claim 11, wherein said issuing means issues the announcement of interruption using a D-channel signal.
- 13. A facsimile system according to claim 11, wherein said issuing means issues the announcement of interruption when any one of no toner, jam of paper and a shortage of paper has occurred in the recording means.
- 14. A facsimile system according to claim 11, wherein said second facsimile apparatus further includes means for determining whether or not an abnormality has occurred in the apparatus during said substituting reception, and means for issuing an announcement of interruption onto said bus when an abnormality has occurred.
