<p>Process and device for the equalization the transmission time To of m radio base stations (RFP) linked through one or more PCM lines to a master unit (MUI). The process consists of measuring the delay (RRS) by which the slave stations receive a reference signal (Tm) emitted by the master unit, and storing in each slave station (RFP) a representative information of the complement of said delay (RRS) with respect to the above-said transmission time To. The device comprises a counter (CK), qualified for the calculation of said reference signal (Tm), set up by the synchronism signal allocated in the time slot zero of the PCM frame, and blocked by a signal (r) available at the output of a recognition unit of the time slot zero of the PCM frame emitted by the interlocutor station. <IMAGE></p> |
