Abstract
Cordless telephones according to the DECT standard are constantly transmitting a so-called dummy barrier at a certain power level, repetition interval and transmit frequency to apply corrections to the synchronization counters in the portable parts for synchronization to the fixed part. According to the present invention, once timing of the portable part is synchronized to the fixed part, a wired connection is used for applying these small synchronization corrections with respect to the synchronization between the portable part and the fixed part of the DECT telephone system. Advantageously, an emission of electromagnetic energy is thereby reduced significantly.
