Abstract

PURPOSE:To decrease delay in an asynchronizing signal through a loop by storing a slot to an output of a sub transmission line to convert the signal into the speed and frame format of the sub transmission line, storing the signal inputted asynchronizingly to the sub transmission line and inserting the result to an idle slot of the main transmission line output synchronizingly. CONSTITUTION:A means 13 analyzing a header decodes the header of the signal inputted from a main transmission line input 1-1, the signal given to the main transmission line output 1-2 is passed as it is by the selector means 18, the signal given to the sub transmission line output 2-2 is stored by a buffer means 17 storing and revising it, and the result is outputted while being revised into the speed and frame format of the sub transmission line 2. Moreover, the asynchronizing signal given to the sub transmission line 2-1 is stored by a buffer means 16 storing and inserting the signal and inserted synchronizingly to an idle slot of the output of the main transmission line. Thus, the waiting delay of the signal passing through the main transmission line 1 is avoided.
