The invention relates to a method for receiving a signal used in a synchronous digital telecommunication system. The method comprises pointer interpretation in which the receiver has three possible main states (NORM, AIS, LOP), between which it undergoes transitions under the control of event counters. In order for fault tolerance to be improved and correction of error situations to be expedited, in the normal state (i) all the events in which the value "normal" (NDF-disabled) of the new data flag is received, and the majority of the I-bits is inverted, and the majority of the D-bits is not inverted are regarded as increment data, and (ii) all the events in which the value "normal" (NDF-disabled) of the new data flag is received, and the majority of the D-bits is inverted, and the majority of the I-bits is not inverted, are regarded as decrement data, wherein the value "normal" for the new data flag is considered to be "0110" and values differing therefrom within certain limits. |
