<P>PROBLEM TO BE SOLVED: To quickly perform resynchronization by instantly determining divergence of an equalization device due to out-of-sync, line disconnection and the like. <P>SOLUTION: An out-of-sync determination processing unit 104 determines whether or not there is out-of-sync or disconnection of a communication line on the basis of at least one piece of information of an equalization error at the time of training completion output from an equalization processing unit 101 and the repetition consecutive number of a hard determination value of the same pattern output from a consecutive detection processing unit 103, and when the situation satisfies at least one of conditions that the equalization error is at or above a threshold value and the repetition consecutive number of the hard determination value is at or above N, determines out-of-sync or line disconnection. A line disconnection determination processing unit 105 determines whether there is line disconnection or not on the basis of an out-of-sync determination result output from the out-of-sync determination processing unit 104 and information on an RSSI output from an RSSI calculation unit 102, and determines there is line disconnection when out-of-sync and the RSSI is at or below a threshold value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
