Abstract: PURPOSE: An apparatus for controlling the creation of a data carrier detection signal in a communication system is provided to improve a packet transfer rate by normally maintaining a transmission line link connection state even in case that a synchronous signal is not detected in a moment. CONSTITUTION: An apparatus for controlling the creation of a data carrier detection signal in a communication system comprises a control part(110), a transmission module(120), and a data processing module. The transmission module(120) comprises a synchronous signal extraction part(120-1), a comparison part(120-2), an up/down counter(120-3), a synchronous signal judgement part(120-4), and a data carrier detection signal creation part(120-5). The synchronous signal extraction part(120-1) extracts the signals received to a channel, transmitting synchronous signals, among the signals received through a transmission line. The comparison part(120-2) compares the pattern of an extracted synchronous signal with the pattern of an initialized synchronous signal. In case that the patterns are matched, the up/down counter(120-3) executes up counting. If the patterns are not matched, the up/down counter(120-3) executes down counting. The synchronous signal judgement part(120-4) compares the counting value of the up/down counter(120-3) with a critical value. If the counting value exceeds the critical value, the synchronous signal judgement part(120-4) judges that a synchronous signal was detected. The data carrier detection signal creation part(120-5) creates a data carrier detection control signal corresponding to the logic state of a carrier detection control signal supplied from the control part(110) and transmits the created signal to the data processing module.
