A method for improving management of pointer processing for concatenated and/or not concatenated payload in SDH/SONET frames is described. The method comprises the steps of: receiving separate indications about the status of single tributaries, the indications comprising Normal State (NORM), Concatenated State (CONC), Loss of Pointer (LOP) and Alarm Indication Signal (AIS), processing, according to a pure combinatorial logic, the separate indications; and in case one of preset concatenation statuses is identified, such an identified current status of received flow of SDH/SONET frames is promptly declared or, in case no preset concatenation statuses are identified the tributaries are treated as stand alone. Differently from the prior art, the step of declaring a concatenation state is performed independently from a previously stored concatenation level.
