<p>PURPOSE:To implement cell priority control without different cell input sequence and output sequence in an output buffer type ATM exchange. CONSTITUTION:In the cell priority control output buffer device in the output buffer type ATM exchange, a post-stage output buffer circuit 3 outputs a buffer overflow signal 4 when a cell input exceeds a buffer allowable value. A low priority cell abort circuit 1 placed at a pre-stage of a pre-stage output buffer circuit 2 located at a pre-stage of the post-stage output buffer circuit 3 aborts a low priority cell when the post-stage output buffer circuit 3 outputs the buffer overflow signal 4 to apply cell priority control without difference of cell input sequence and output sequence.</p> |
