Problems solved by technology

To achieve impedance matching at the receiving end, it is necessary to manually control the opening and closing of the dial switch, which is prone to misoperation
More importantly, due to the high failure rate of relays and DIP switches, once they fail, the link will be broken

Embodiment Construction

[0047] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] As shown in Figure 2, it is a flow chart of the first embodiment of the method of the present invention, comprising steps:

[0049] S201. After receiving the link configuration information of the active interface board, the standby interface board performs link configuration on the standby interface board according to the configuration information;

[0050] S202. The standby interface board opens the transmission port of the standby interface board after learning that the main interface board shuts off its transmission port or sets the output to high impedance;

[0051] S203. After learning that the active interface board has set the receiving impedance of the active interface board to infinity, the standby interface board sets the receiving impedance of the receiving port of the standby interface board according to the link...

Abstract

The embodiment of the invention discloses a main / standby switch method of an interface board, which comprises the following steps: after the link configuration information of a main interface board is received by a standby interface board, the link configuration is performed to the standby interface board according to the configuration information; after the standby interface board learns that the sending port of the main interface board is closed or the output is set as high resistance, the sending port of the standby interface board is opened; after the standby interface board learns that the receiving resistance of the main interface board is set to be infinitely great by the main interface board, the receiving resistance of the receiving port of the standby interface board is set according to the link condition. The invention also discloses a main / standby switch system of an interface board and an interface board for realizing the main / standby switch, by utilizing the embodiment of the invention, the online hot backup of the interface board can be realized, and the main / standby switch of the interface board can be realized without interrupting the external service of the interface board.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a system for active / standby switchover of an interface board and an interface board capable of realizing active / standby switchover. Background technique [0002] The interface board is a bridge connecting the BTS (Base Transceiver Station, Base Transceiver Station) and the BSC (BaseStation Controller), and the reliability of the connection between the BTS and the BSC can be greatly improved by making active / standby backup of the interface board. In the prior art, the active / standby backup of the interface board is implemented through the switching of relays. As shown in FIG. 1 , it is a schematic circuit diagram of active and standby backup in the prior art. The relay controls whether the sending and receiving of the board is connected to the line. When the board is in main use, the switch of the relay at the sending end is closed so that the signal can be tra...
