Adopt the method for the invention and device, compared with prior art, make standby cross board slot position when not inserting cross board, can insert business board, increased the access number of slots amount of system, and standby cross board slot position is when inserting cross board, can not reduce the total service access capacity of system, total service access capacity of system can not change.
Embodiment
The present invention is in order to solve the drawback that conventional solution exists, further set forth the method and apparatus of the compatible professional board slot of a kind of SDH equipment sparing cross board slot position of the present invention position by following examples, below embodiment is described in detail, but not as a limitation of the invention.
Directly do not occupy the service access capacity of system for the service access capacity that makes standby cross board slot position, that is to say no matter standby cross board slot position is inserted cross board or business board, total access capacity of system can not change, the described method and apparatus of the embodiment of the invention, make the compatible professional board slot of standby cross board slot position position, when standby cross board slot position is not inserted standby cross board, insert business board, make the service signal that standby cross board slot position and a certain professional groove position provide share a part of bandwidth, determine that according to the plate type service signal that service signal that standby cross board slot position provides or professional groove position provide advances cross matrix on cross board then.
For example, the service access capacity of No. 1 standby cross board slot position is A, and the service access capacity of No. 2 professional board slot positions is that (A＜B), that can allow the A capacity bandwidth of A capacity shared system of the A capacity of No. 1 standby cross board slot position and No. 2 professional board slot position parts to B.When No. 1 standby cross board slot position was inserted cross board, the service access capacity of No. 2 professional board slot positions was B, and when No. 1 standby cross board slot position was inserted business board, the service access capacity of No. 2 professional groove positions was reduced to B-A.Design has increased the access number of slots amount of system like this, does not influence total service access capacity of system again.
In order to make standby cross board slot position and professional board slot position compatibility, described standby cross board slot position is identical with the backboard jack interface signal location of the veneer common part of professional board slot position except that holding wire.
After reaching the compatible professional board slot of standby cross board slot position position, the immovable purpose of total service access capacity of system, the service signal shared bandwidth that standby cross board slot position and professional board slot position provide.
And, the service signal interface that described standby cross board slot position provides, identical with the position of the service signal interface of professional board slot position, and the service access capacity that provides of standby cross board position is less than the service access total capacity of business board.
With the service signal that standby cross board slot position provides, introduce the cross board input port jointly with service signal described shared bandwidth with professional board slot position is that provide; Plate type according to the insertion of corresponding standby cross board slot position, selection is the service signal from standby cross board slot position, still the service signal from professional board slot position enters cross matrix: when standby cross board slot position is inserted standby cross board, the service signal of selecting professional board slot position to provide enters cross matrix, if standby cross board slot position is inserted business board, the service signal of selecting standby cross board slot position to provide enters cross matrix.
Delivery outlet at cross board, selection is to output to standby cross board slot position from the signal of cross matrix output, still output to professional board slot position: when standby cross board slot position is inserted standby cross board, to output to professional board slot position from the signal of cross matrix output, when standby cross board slot position is inserted business board, will output to standby cross board slot position from the signal of cross matrix output.
Below with an application example explanation the method for the invention: for the systems that 5 masters are arranged with cross board slot position and 5 standby cross board slot position, the service access capacity of professional board slot position is 20G.The service signal that we can design 5 standby cross board slot position and 5 corresponding professional board slot positions provides is shared the bandwidth of 10G respectively.When standby cross board slot position was inserted cross board, the access capacity of corresponding service board slot position was 20G.When standby cross board slot position was inserted business board, the service access capacity that this standby cross board position provides was 10G, and the service access capacity of corresponding service board slot position is 10G.
Can insert the standby cross board of respective numbers according to user's different demands like this, remaining standby cross board position just can be used as professional board slot position.Objectively, the access number of slots amount of system is increased, total and the access capacity of system can not change with the quantity of inserting standby cross board is different.
The described device of the embodiment of the invention comprises standby cross board slot position and professional board slot position, the compatible standby cross board slot position of standby cross board slot position.
In order to make described cross board slot position and professional board slot position compatibility, described standby cross board slot position is identical with the backboard jack interface signal location of the veneer common part of professional board slot position except that holding wire.
After reaching the compatible professional board slot of standby cross board slot position position, the immovable purpose of total service access capacity of system, the service signal shared bandwidth that standby cross board slot position and professional board slot position provide.
The service signal interface that described standby cross board slot position provides, identical with the position of the service signal interface of professional board slot position, and the service access capacity of standby cross board slot position is less than the service access total capacity of professional board slot position.
The service signal that standby cross board slot position provides is introduced the cross board input port with professional board slot position is that provide jointly with service signal described shared bandwidth; When standby cross board slot position was inserted standby cross board, the service signal that professional board slot position provides entered cross matrix, if standby cross board slot position is inserted business board, the service signal that standby cross board slot position provides enters cross matrix.
At the delivery outlet of cross board, when standby cross board slot position was inserted standby cross board, the signal of exporting from cross matrix outputed to professional board slot position, and when standby cross board slot position was inserted business board, the signal of exporting from cross matrix outputed to standby cross board slot position.
Adopt the described method and apparatus of the embodiment of the invention, cross board backup protection scheme flexibly can be provided according to user's demand, can insert business board, make the access groove position maximization of system in the standby cross board slot position of free time.No matter standby cross board slot position is inserted standby cross board and is still inserted business board, and total access capacity of system can not change.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and modification according to the present invention, but these corresponding changes and modification all should belong to the protection range of the appended claim of the present invention.
