TFU CONNECTING DEVICE OF THE WLL SYSTEM AND CONTROLLING METHOD THEREFORE

摘要

The invention UCPA-T board is at least periodically transmitted to a specific signal for knowing the abnormal state of the other CIGA board to active the CIGA board status check signal transmitting step, and make the abnormality signal to operate in the TFU for PCS active no response from the other party CIGA board on the response signal received confirmation steps to verify whether or opponent active in the response signal received from CIGA board for a particular signal are transmitted after the transmitting step, the specific signal is currently transmitted in the acknowledgment step the response signal If the number exceeds the predetermined reference number of times hayeoteul provides tiepeu oil connection device and a control method of a wireless network system consisting of a transfer execution step of switching and transmits it to the normal CIGA board the switching request signal.; The present invention as described above are each individually connected with a connection TFU board and for the PCS system coupled to CIGA board consisting of a redundancy of WLL system, in which the return to the active state TFU board issues a periodic checking signal to the GIGA board by running a transfer board according to the result, it is not necessary to connect the port to the redundancy between the board and the TFU CIGA board consisting of redundancy to prevent the operation error of the WLL system, which may be caused by the connection of the different nodes based above.
