<p>Improved interface system for synchronous hierarchy telecommunication networks, in particular SDH networks, comprising a high frequency backpanel function, said system comprising at least a central board (CM, CB1, CB2) and one or more input/output peripheral board (PD) apt to exchange data frames (TRM1, TRM2, TRU1, TRU2) and control bytes (A1, A2, SY, H4, L). According to the invention, the data frames (TRM1, TRM2, TRU1, TRU2) contain control bytes (A1, A2, SY, H4, L) and said data frames (TRM1, TRM2, TRU1, TRU2) are bitwise converted before being exchanged between the peripheral boards (PD) and the central board (CM, CB1, CB2). <IMAGE></p> |
