Connecting traditional voice and data over Ethernet network has become an attractive approach. It saves money on voice call and leased-line service charges, while consolidating management, cutting maintenance costs, and increasing user productivity. This is achieved by converging two important traffic types into one infrastructure and take advantage of the simplicity and efficiency of Ethernet switching. In this thesis, the main research is designing a line card that can carrier the E1(2.048MHz)/T1(1.544MHz) data over Ethernet frame and use Ethernet switch to transmit the frame.
