Communication connecting device and data output control method

摘要

In an Internet facsimile apparatus (10), a facsimile controller (12) temporarily stores data received from a G3 (Group 3) facsimile apparatus (30) or the other terminal unit to communicate with. A packetizer/depacketizer (14) packetizes the data sequentially read out in accordance with size information fed from a size information storage (16) and feeds the resulting packets to a UDPTL controller (18) and a buffer (20). The packetizer/depacketizer (14) determines whether data received from the other terminal unit and decoded is a response to data sent from the G3 facsimile apparatus (30) or retransmitted data, and delivers a response detection signal representative of the result of decision to the UDPTL controller (19) . In the UDPTL controller (18) , a filtering circuit (180) deletes stored past data in accordance with the response detection signal representative of a response. The apparatus reduces a load on an IP (Internet Protocol) network.
