An erroneous synchronization preventing device includes a pattern detector detecting a sync pattern from received data with a broader sync window to output a sync detection notice and a sync timing. On receipt of the notice, a packet header detector checks an error in a header field of the received data, and, if detecting no error, outputs a header-normally-received notice, on receipt of which the timing corrector makes the inner timing synchronous with the sync timing to output a timing correction end notice. The mode manager in turn outputs a change notice. The pattern detector then detects the sync pattern with a narrower sync window. Unless the end notice is received within a predetermined period as from receipt of the change notice, a detection period monitor outputs an out-of-synchronism notice. The mode manager then outputs a restoration command for instructing detection of the sync pattern with the broader sync window. Disconnection of a communication link due to erroneous synchronization will be avoided.
