PURPOSE:To improve re-clocking by writing a data signal of a burst of its own subordinate station into a FIFO memory synchronously with a clock recovered from the burst and reading the data from the FIFO memory with a stable clock. CONSTITUTION:Its own station burst detection circuit 4 detects a burst of its own subordinate station from a TDM signal and uses a switch circuit 1 to select an n-channel TDM signal relating to a data signal and writes the data signal of the burst of its own subordinate station from the n-channel TDM signal relating to the data signal outputted from the switch circuit l into a FIFO memory 5 by using a clock synchronously with the data signal. The data signal is read from the FIFO memory 5 by using a stable clock. Thus, the data signal read according to the stable clock in its own system is outputted from the FIFO memory. |
