BULK COMMUNICATION CONTROL DEVICE AND BULK COMMUNICATION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a bulk communication control device which performs a bulk communication by bundling only successful channels when the connection or bulk procedure of all channels is not made successful. SOLUTION: The bulk communication control device 1 comprises: a terminal interface part 11 for communicating with a data terminal device 3 at an arbitrary communication velocity; line interfaces 14 and 15 for performing communications by a plurality of channels between communication lines 5 and 6; a line control part 13 for carrying out call control with the communication lines; and a data control part 12 having a line delay time detecting part for detecting a line delay time difference for each channel, a training data transmitting/receiving part for transmitting/receiving bulk communication training data and a velocity matching part for matching the velocities of data received from the communication lines on the basis of the detection data of the delay time detecting part. The bulk communication is performed by using the channel in which delay corrected data are successfully transmitted/received within a prescribed time by acquiring the delay correction data while using the channel in which call setting is made successful within the prescribed time.
