Embodiment Construction

[0013] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0014] Fig. 1 is the structural schematic diagram of the existing main and backup device with an external plus one-of-two circuit. With reference to Fig. 1, in this service interface board backup mode, the two service interface boards connect the outside lines and the main and backup control lines through the backplane. To the outside, place a two-choice circuit outside, control the outside two-choice circuit through the main and backup control lines, and select different lines to connect with the outside line to achieve the purpose of backup. There are many control circuits in this way, the structure is complex, and it is unreliable.

[0015] FIG. 2 is a schematic structural diagram of an existing master-slave device. Referring to FIG. 2 , this is another service interface board backup method in the prior art. This method generally adopt...

Abstract

The invention discloses a business interface board standby device for the communication system. The device includes: a set of jumping wire behind the back plate which is used to finish the connection between the external wires of two near business boards; one jumping wire under work module behind the back board or other no source switch which are used to set the work mode of two near block plate; a relay is mounted in the interface of business which is used to connect or disconnect the external wires. The business interface board standby device has simple structure, configures agility, and easy to operate.

Description

technical field [0001] The invention relates to the field of communication, and more specifically relates to a main backup device of a service interface board of communication equipment. Background technique [0002] For switches, dispatchers or other equipment in the communication field, in order to ensure the stable operation of the equipment, important interface boards are required to be backed up. When a service interface board fails, another service interface board can take over. interruption. [0003] In the prior art, there are two types of backups for the service interface boards: one is to add a two-choice circuit on the backplane or outside the backplane; the other is that the status of the two service interface boards is a master-slave relationship. It is connected to the external line, and the spare is not connected to the external line. When the main board fails, the main board switches the external line to the slave board through the relay on the board, so tha...
