ABSTRACT:
A communication connecting device includes a terminal unit controller for temporarily storing data received from a sending terminal unit. A packetizer/depacketizer collectively codes the data sequentially read out in accordance with size information fed from a size information storage. The packetizer/depacketizer determines whether or not the data is control data and delivers, if the answer of the decision is positive, a notification control signal to a control data monitor. A UDPTL (facsimile User Datagram Protocol Transport Layer protocol) controller feeds a UDPTL packet input from the packetizer/depacketizer to the control data monitor in accordance with ITU-T (International Telecommunication Union-Telecommunication standardization sector) Recommendation T.38. The control data monitor repeatedly sends the UDPTL packet on the basis of the notification control signal.
