Abstract
A simple synchronizing detection circuit is provided in each of logical operation circuits, and a method for making a synchronizing detection in parallel is adopted. A selector control section monitors the states of the simple synchronizing detection circuits in parallel, and supplies an output from a proper logical operation circuit detecting the synchronization establishment to a frame synchronizing/terminating circuit at the latter stage. There is provided a function of relieving a synchronization determination condition if the synchronization establishment is not detected in any of the synchronizing detection circuits, whereby the output from the proper logical operation circuit can be selected depending on a load on a transmission path.
