The embodiment of the invention discloses a E1 bidirectional ring network data transmission method, device and system, wherein, the E1 node includes: Ethernet transmission unit is connected with the local Ethernet device through the Ethernet port branch, the CPU unit and the first to link port and second port E1 to the chain drive unit comprises the CPU unit; and neighbor E1 node link status detection based on signaling interaction, determine the transmission link failure between the E1 node and neighbor node E1, through the E1 node of the first link to the port and the second port to link, in association with the current transmission link fault, link port outside link port is not available the main transmission link to node fault information, so that the master node of the first link to send data port, Second the mode of receiving data from the link port is switched to the mode of receiving and transmitting data. The embodiment of the invention can effectively improve the survivability of the E1 bidirectional ring network.
