Abstract
(EN)
A transmission apparatus (4a) comprises a setting part (corresponding to a LAN mapping circuit 100a) that sets a wireless line, which transmits a frame having a particular frame structure, and a wireless line, which transmits a packet, for each of wireless lines (1, 2); and a transmitting part (corresponding to a LAN packet dividing circuit 200a, an E1 framing circuit 300a, a LAN packet reproducing circuit 400a, a buffer circuit 500a, a selector circuit 600a and demultiplexing circuit 700a) that uses the wireless lines (1, 2) to transmit the frame and the packet in accordance with information (LAN mapping information 101a) set by the setting part (100a).
(FR)
L'appareil de transmission (4a) selon l'invention comprend une partie réglage (qui correspond à un circuit de mise en correspondance de LAN 100a) qui règle une ligne sans fil, qui transmet une trame présentant une structure de trame particulière et une ligne sans fil, qui transmet un paquet pour chacune des lignes sans fil (1, 2) ; et une partie transmission (qui correspond à un circuit de division de paquet de LAN 200a, à un circuit de mise en trame E1 300a, à un circuit de reproduction de paquet de LAN 400a, à un circuit tampon 500a, à un circuit sélecteur 600a et à un circuit de démultiplexage 700a) qui utilise les lignes sans fil (1, 2) de manière à transmettre la trame et le paquet selon les informations (informations de mise en correspondance de LAN 101a) réglées par la partie réglage (100a).
(JA)
