Abstract
Disclosed are a signal control apparatus, a transmission system and a signal resynchronization control method, which efficiently prevent the occurrence of slipping and execute high-quality signal resynchronization control. The signal control apparatus comprises a serial/parallel converting section, a window setting section and a parallel/serial converting section. The serial/parallel converting section performs serial/parallel conversion on an input signal to yield parallel data. The window setting section sets a small window having a readout guarantee area narrowed at an optimal position at the time of reading the parallel data when an operational state is unstable, and sets a large window having the readout guarantee area widened from the optimal position when the operational state is stable. The parallel/serial converting section reads the parallel data based on a read pulse positioned within the readout guarantee area corresponding to the small window or the large window, and performs parallel/serial conversion on the parallel data to yield serial data. The transmission system comprises a plurality of transmission apparatuses each including the above signal control apparatus, and a transmission medium for connecting the transmission apparatuses. The signal resynchronization control method executes signal resynchronization control by performing the functions of the individual sections of the signal control apparatus.
