摘要：
The present invention discloses a communication system having backup function for several series communication devices. The apparatus comprises at least a line adapter unit having multipath inputs and multipath outputs. The series communication devices are cascaded by the line adapter unit. The port connected to the line adapter unit on the main controlling module of the communication devices is open, and the port connected to the line adapter unit on the spare controlling module is closed. The present invention also discloses two methods for carrying out the function of switching of the aforementioned communication system. By switching the communication device interfaced with the line adapter unit, the communication devices which are cascaded with said communication device does not need to switch.
