Abstract
A transmission device far efficient synchronous multiplexing control for downsizing and reducing power consumption. A count control performs channel management control on a cross-connect basis using count control of channels of high-bit-rate and low-bit-rare multiplexing unit signals. A part which detects a head position of path information based on pointer value. A part which performs clock exchange with respect to valid path information indicated by head position. A part which generates a write count value, a read count value, and adds a pointer to the valid path information read. A cross-connect circuit uses two-plane memory, and cross-connects a signal with the pointer being replaced by memory reading based on memory switch information.
