Abstract：
 In sending direction, medium independent interface data of LAN A are input to following cascaded parts: Ethernet receiving circuit, FIFO1£¬framing circuit in protocol of high level data link control (HDLC), sending buffer control circuit, E1 sending buffer, E1 sending circuit, and interface circuit of E1 line. In receiving direction, input signal of interface circuit of E1 line passes through following cascaded parts: E1 receiving circuit, E1 receiving buffer, receiving buffer control circuit, de-framing circuit in protocol of HDLC, FIFO2, sending circuit of Ethernet, then through medium independent interface, data inputted to LAN B. in the system, after Ethernet data frame reaches, each E1 line is polled in sequence. One integrated data frame is transferred in sequence through free line pulled from each route. The invention can eliminate issue of different time delay when one split Ethernet data frame is transferred through multiple routes of E1 line together.
