The business interface board standby device has simple structure, configures agility, and easy to operate.
Description
Technical field
The present invention relates to the communications field, more particularly, relate to a kind of standby and main device of service interface board of communication equipment.
Background technology
Switch, dispatcher or miscellaneous equipment in the communications field, in order to guarantee the stable operation of equipment, the important interface plate all requires backup, and under the situation that certain piece service interface board breaks down, another piece service interface board can be taken over job, and business is not interrupted.
In the prior art, the backup of service interface board has two kinds: a kind of is at backboard or the outside alternative circuit that increases of backboard; Another kind is two relations that the service interface board status is the principal and subordinate, has only main being connected with outside line, and what be equipped with is not connected with outside line, and when mainboard came out fault, mainboard switched to slave plate to outside line by the relay in the plate, allows slave plate work.The shortcoming of this method is, the mainboard of having gone bad can not be extracted maintenance, and whole communication equipment is quit work, and changes mainboard and slave plate.
Summary of the invention
In order to overcome deficiency of the prior art, the object of the present invention is to provide a kind of service interface board standby and main device that is used for communication system, can not extract the problem of maintenance when breaking down with the service interface board mainboard that solves communication equipment.
For realizing above-mentioned goal of the invention, the invention provides a kind of service interface board standby and main device that is used for communication system, comprise relay, backboard outside line interconnection wire jumper and backplane active/standby mode of operation wire jumper in the service interface board.It is characterized in that:
Described backboard outside line interconnection wire jumper is used to be switched on or switched off being connected of adjacent 2 service interface boards and outside line;
The described active and standby mode of operation wire jumper of using is used to be provided with the mode of operation of 2 service interface boards, connects when wire jumper, and 2 service interface boards work in the active and standby pattern of use, and when the wire jumper disconnection, 2 service interface boards work in the non-active and standby pattern of using.
Relay in the described service interface board is used to connect or disconnect being connected of service interface board and outside line.
According to a kind of service interface board standby and main device that is used for communication system of the present invention compared with prior art, have simple in structure, flexible configuration and advantage such as simple, convenient.
Description of drawings
Fig. 1 adds the standby and main device structural representation of alternative circuit for existing outside;
Fig. 2 is the standby and main device structural representation of existing employing master-slave mode;
Fig. 3 is a standby and main device structure chart of the present invention.
Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described.
Fig. 1 adds the standby and main device structural representation of alternative circuit for existing outside, with reference to figure 1, in this service interface board backup mode, two service interface boards are outside line and active and standbyly all link the outside by backboard with control line, place the circuit of alternative outside, by active and standby alternative circuit with control line control outside, the different circuit of gating links to each other with outside line, reaches the purpose of backup.This mode control circuit is many, and complex structure is unreliable.
Fig. 2 is the standby and main device structural representation of existing employing master-slave mode, and with reference to figure 2, this is an another kind of service interface board backup mode of the prior art, and this mode generally adopts the N+1 backup mode.The N+1 backup mode is that a plate backs up for simultaneously the polylith plate.The circuit structure of this backup mode is such: each piece circuit board all has outside line separately, and each piece plate has relay to get to outside line on the backup bus of backboard, and the backup bus of polylith plate links to each other.Standby plate does not have outside line, and its interface circuit is linked on the backup bus.When main board A broke down, main board A received outside line on the backup bus, and standby plate B receives outside line and works on, and reaches the purpose of backup.At this moment main board A can not extract maintenance.This backup mode also has a shortcoming to be, owing to adopt a plate to back up for the polylith plate, can not have 2 blocks of plates to break down simultaneously, otherwise not reach the purpose of backup, because can not link many outside lines simultaneously on the backup bus.
Fig. 3 is a standby and main device structure chart of the present invention, and referring to Fig. 3, the standby and main device of service interface board of the present invention mainly comprises:
Backboard outside line interconnection wire jumper is used to finish the outside line connection of adjacent 2 business boards.The quantity of wire jumper is relevant with the way that service interface board is supported, 2 lines in every road need 2 wire jumpers.When 2 blocks of adjacent plates need back up, have only in 2 blocks of plates on the Europlug behind the B plate and insert external cable, the wire jumper behind A, the B plate is connected, this outside line just can be linked A plate and B plate simultaneously.
The active and standby mode of operation wire jumper of using is used for being provided with the active and standby mode of operation of using of adjacent 2 blocks of plates.This wire jumper is connected, and is set to the active and standby mode of operation of using for 2 veneers; This wire jumper disconnects, and is set to the non-active and standby mode of operation of using for 2 veneers.Require active and standbyly to be provided with the outside line wire jumper, be operated in active and standbyly when using mode of operation, connect together, be operated in non-active and standbyly when using mode of operation, disconnect together with the mode of operation wire jumper.The active and standby mode of operation wire jumper of using also can replace with other passive switch.
Be placed on the relay in the service interface board, be used to connect or disconnect service interface board and be connected with outside line.The quantity of relay is relevant with the way that interface board is supported, every road needs 1 relay.When 2 blocks of plates work in active and standby when using pattern, according to the active and standby logic of using in 2 blocks of plates, the relays in 2 blocks of plate plates whenever only the relay in plate connect, the relay of another piece plate disconnects.So just can realize having only the circuit of a plate to link to each other with outside line, the veneer that links to each other with outside line is exactly a main board, and the veneer that disconnects with outside line is exactly a standby plate.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
