Abstract:
In a facsimile system adapted to receive data via a LAN (Internet facsimile system), when the facsimile machine is unable to print or otherwise process the received data, and has no mass storage device, the received data is rerouted to the other terminal connected to the LAN so that the received data may be readily retrieved at all times. Such a situation can occur as a result of a failure of the printer unit, running out of printing paper, experiencing an unchanged state of the image memory for more than a prescribed time period, experiencing a memory-full state of the image memory for more than a prescribed time period, and detecting the received data to be based on a format which the facsimile system is unable to handle. Therefore, the received data can be made readily available for the interested party, and the safety of the received data can be improved.
Abstract:
The Internet facsimile apparatus in the present invention is provided with data memories such as telephone book data memory, relay FAX data memory and adjacent district number memory. Its collation section collates the telephone number of the recipient with the data of the telephone book memory, then the relay destination search section searches for data in the relay FAX data memory and obtains the address of a relay apparatus candidate. If there is no appropriate relay apparatus in the same district, the adjacent district number search section searches for the number of an adjacent district and continues the search based on the district number. In this way, when carrying out image transmission using the Internet facsimile apparatus as a relay apparatus, the nearest Internet facsimile apparatus suitable for use as a relay apparatus is automatically selected.
Abstract:
Upon occurrence of memory overflow, a POP3 protocol process section interrupts email reception by POP3 and stores a page count number at the interruption in the data memory area as the interrupted page number. After that, POP3 protocol process section starts reception of the remainder of the interrupted email data connecting to POP3 server. Comparing the receiving page number and the interrupted page number, the POP3 protocol section identifies the data as the data corresponding to the pages received if the former number is smaller than the latter number. If the data corresponds to the pages received, the data is deleted from the reception buffer without any processing. On the other hand, if the data corresponds to non-received pages, then the data is received and printed out after decoding.
Abstract:
A terminal adapter unit for use in a wide-band network based on an ISDN is connected in the data path between a data terminal and the ISDN, and functions to control accessing and releasing a line through the ISDN to an opposite data terminal, in accordance with whether or not data are actually being transferred between the terminals. Unnecessary line utilization costs can thereby be reduced since lengthy intervals in which the terminals are accessing the ISDN while the data transfer is interrupted, due to a data terminal failure or operating error, can be eliminated.
