Patent ID: 8542600

Claim:
An image communicating apparatus comprising: a main control portion; a storing portion storing instructions which when executed cause the main control portion to act as: a packet control portion that transmits/receives an Internet Facsimile Protocol packet by a T.38 communicating function; and an image communicating control portion that describes a T.30 command and image information in a field of the Internet Facsimile Protocol packet to control an image communication, the packet control portion including: a counting unit that counts a total number of received packets and a number of loss packets in the Internet Facsimile Protocol packet in a receipt of the image information, and the image communicating control portion including: a calculating unit that calculates a loss ratio of the Internet Facsimile Protocol packet in the receipt of the image information from a rate of the number of loss packets to the total number of received packets which is counted by the counting unit in a receipt of a post message; and a response signal returning unit that returns a retraining negative signal to an apparatus on a transmitting side for the image information in response to the post message if the loss ratio calculated by the calculating unit exceeds a first threshold, and returns a message confirming signal to the apparatus on the transmitting side in response to the post message if the loss ratio calculated by the calculating unit is equal to or smaller than the first threshold; and a communication interrupting unit that interrupts a communication if the loss ratio calculated by the calculating unit exceeds a second threshold which is greater than the first threshold.
