Abstract: A system and/or method for recognizing and tracking the sampling phase of a signal received in a local terminal from a remote terminal in digital synchronous transmission systems, said local terminal being associated with a local clock signal also used to synchronize the remote terminal. According to this invention said system for recognizing and tracking the sampling phase (DPA) comprises means (QUAD; QUAD1) able to obtain a plurality of clock signals with determined phase differences to each other (CK, CKQ, CKN, CKQN) from said local clock signal (CK), and means (1,2,3,5,6) able to select a sampling clock signal (CKSEL) of the received signal (DTP) among the plurality of clock signals (CK, CKQ,CKN, CKQN) with determined phase differences to each other, which has a phase substantially coinciding with the phase of the signal received (DTP).
