The ATCA expanded back panel comprises at least two connector groups, wherein each connector group comprises two connectors; the two connectors are interconnected with a power line through a data line and are respectively a forward connector connected with an external ATCA front plugboard and a backward connector connected with an external ATCA back plugboard; and in the at least two connector groups, at least one connector in at least one connector group is connected with at least one connector in the other at least one connector group.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of advanced telecommunication computing structure ATCA expansion backboard and system.
Background technology
Along with development of Communication Technique, more and more higher to the requirement of capacity, reliability, extensibility and the manageability of communication facilities.Comply with this development, PCI industrial computer manufacturer group (PCI Industrial ComputerManufacturer ' s Group, abbreviation PICMG) a kind of advanced telecommunication computing structure (AdvancedTelecom Computing Architecture has been proposed, be called for short ATCA), and formulated the PICMG3.0 standard, detailed regulation has been carried out in aspects such as the physical construction of ATCA, power supply, heat radiation, system management, data transmission interface, backboard specification.
In PICMG 3.0 standards, ATCA veneer and machine frame size have been defined, as shown in Figure 1, the ATCA veneer comprises: front card 1, back card/back board 2 and backboard 3, wherein, backboard 3 can comprise a plurality of grooves position, be respectively applied for and insert a plurality of front cards 1, interface between front card 1 and the backboard 3 is divided into Zone1 district and Zone2 district two parts according to function, the Zone1 district mainly finishes power supply and inserts, functions such as system management, Zone2 finishes in the district transmission of business datum, is used to connect the Zone1 district of backboard 3 and Zone2 district by normalized definition, has guaranteed that the ATCA veneer of all producers can be compatible.Interface definition between front card 1 and the back card/back board 2 is in the Zone3 district, this is a zone that is positioned at backboard 3 tops, front card 1 all is not connected with backboard 3 herein with back card/back board 2, and front card 1 directly links to each other with back card/back board 2, the Zone3 district that is used to connect back card/back board 2 is can be self-defining, the Zone3 area definition of different manufacturers has nothing in common with each other, so the front card 1 of ATCA veneer and back card/back board 3 all are matching used.
When realizing technical scheme of the present invention, the inventor finds, the back card/back board of the ATCA veneer that prior art provides and front card are by the directly butt joint of Zone3 district, back card/back board only has unique annexation with it to the front card of inserting, front card provides data and power supply to back card/back board, back card/back board is the expansion of front card, be not related with other veneer and backboard, the i.e. unique binding of the front card of an ATCA veneer and back card/back board, the power supply that front card provides to back card/back board, if front card pulls out, insert the back does not just have power supply, and back card/back board just can't be worked; The data of back card/back board interface can only be given front card, if the front card fault, the back card/back board data just can not send other veneer to.
Summary of the invention
Embodiment of the invention technical matters to be solved is to provide a kind of advanced telecommunication computing structure ATCA expansion backboard and system, to realize being connected to each other between a plurality of veneers.
The embodiment of the invention provides a kind of advanced telecommunication computing structure ATCA expansion backboard, described expansion backboard comprises at least two connector groups, comprise two connectors in each connector group, described two connectors are respectively: described preceding socket, connector that links to each other with outside ATCA front card and the back socket, connector that is used for linking to each other with outside ATCA back card/back board of being used for by data line and power lead interconnection; And in described at least two connector groups, at least one connector at least one the connector group of at least one connector and other at least one connector group is connected.
The embodiment of the invention also provides a kind of advanced telecommunication computing structure ATCA system, comprising: at least two front cards, at least two back card/back boards and expansion backboard; Described expansion backboard comprises at least two connector groups, comprises two connectors in each connector group, and described two connectors are respectively preceding socket, connector and back socket, connector by data line and power lead interconnection; And in described at least two connector groups, at least one connector at least one the connector group of at least one connector and other at least one connector group is connected; Described at least two front cards link to each other with preceding socket, connector in described two connector groups respectively at least; Described at least two back card/back boards link to each other with back socket, connector in described two connector groups respectively at least.
In the technical scheme of the embodiment of the invention, by an expansion backboard, can realize under the situation that takies the less groove of backboard position that the front card of a plurality of ATCA veneers is connected with expansion between the back card/back board, the preceding socket, connector of expansion backboard is connected with front card, a plurality of backs socket, connector of expansion backboard is connected with back card/back board, can realize front card or a plurality of back card/back board interconnection that links to each other with the back socket, connector that a plurality of and preceding socket, connector links to each other, help alleviating unique powerup issue of ATCA veneer, help data transmission, backup and load sharing between a plurality of veneers.
