摘要： A transmission device comprises first interfaces each of which receives time-division multiplexed signals from an external device in units of frames, a switch which is connected with the first interfaces and sets paths of the signals received from the first interface in regard to each packet, and second interfaces each of which is connected with the switch, receives the signals from the first interface via the switch, and transmits the received signals to a different transmission device in units of packets. The first interface selects signals having the same destination from the signals contained in the received frame and stores the selected signals having the same destination in one packet.

摘要： When multiple SDH/SONET frame are accumulated and then lower-order path information removed from multiple frames is multiplexed into the same packet to achieve better transmission efficiency during packetization, the delay for accumulating increases. Disclosed is a transmission device that packetizes an SDH/SONET lower-order path with timing which is an integer factor of 1 cycle of the SDH frame. In this case, the destination loads the same multiple lower-order path in one packet. The result is that delay time accompanying lower-order path packetization is kept to less than the time of 1 cycle of the SDH frame, and the efficiency with which lower-order paths are accommodated in packets is further increased. The result is that improved transmission efficiency is realized.
