Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To attain a highly reliable test by preventing an output of a loopback signal for a period from start of a local loopback test till the end of on-pattern of pseudo carrier OFF so as to prevent mismatching of data collation just after loop forming. SOLUTION: Upon the detection of an on-pattern by a pseudo carrier pattern detection section 109, the section 109 gives an instruction of setting ON of a CD signal to a carrier detection adjustment section 108. Since the CD signal is set at this point of time, the carrier detection adjustment 108 once resets the CD signal and sets it again at the end of the on-pattern. When the CD signal is reset, a CS-CD detection section 111 raises a detection signal S2, and a CD-OFF detection section 110 outputs a detection signal S1 to a reception data adjustment section 106. When the CD signal is set, the CD-OFF detection section 110 descends the detection signal S1. The reception data adjustment section 106 receiving the detection signals S1-S3 always clamps an RD signal to be binary '1'.
