<p>Disclosed is a packet switching xDSL system. A packet based xDSL modem is connected to a data terminal, and executes xDSL modulation and demodulation operations on the data packet transmitted to the data terminal, and transfers the data packet. An xDSL multiplexer converts the signals transmitted/received to the packet based xDSL modem into the data packet, and performs a multiplexing operation using a packet switching engine, and is connected to a basic network. Therefore, since data format between the packet based xDSL modem and the xDSL multiplexer is a packet type and the data format between the xDSL multiplexer and the basic network is also the packet type, the data can be transmitted without an additional ATM protocol, the expense can be cut, and the transmission band can be guaranteed. <IMAGE> <IMAGE></p> |
