Abstract
A method for detecting link crossing misconnect, includes following steps: a), setting all the other end of the link waiting for detection as the out loop back; b) the ports corresponding to the other end of the links waiting for detection are triggered by a command for sending data and meanwhile sends the detection data having port information; c) the each port sending detection data separately decides whether or not the port information in the data sent and received by each port are the same, if yes, the wire splice of this port link is normal, otherwise the wire splice of this port link is incorrect. This invention can also get the exact numbering of misconnected port according to the port information in receiving data and has extensive use in communication equipment.
Description
Technical field
The present invention relates to communication equipment detection technique field, be meant a kind of method that detects link intersection misconnection especially.
Background technology
In telecommunication product, although almost every cable interface side all posts numbering, take place with the situation that prevents link intersection misconnection, in actual applications, still often have the situation of link intersection wrong, this type of situation can not be avoided fully.
Be respectively the schematic diagram of the correct wiring of link and link error wiring between local terminal equipment and the opposite equip. shown in Fig. 1 a, Fig. 1 b.Fig. 1 a is a link wiring schematic diagram correct between local terminal equipment and the opposite equip., Fig. 1 b be local terminal equipment with opposite equip. between link occurs and intersect the wiring schematic diagram of misconnection.Owing in the link of wrong carrier signal is arranged also, so upper layer device generally can not be checked out this mistake.
Usually, the method that detects intersection misconnection link has following two kinds: a kind of method is at the equipment side that link intersection misconnection may occur, by manually all links being checked one by one, check whether it receives link consistent with the numbering that sends link according to cable interface side numbering.Another kind method is at the equipment side that link intersection misconnection may occur, after its all of the port is set to outloop, under artificial control, each port of local terminal equipment sends data one by one, detect it whether data loopback is arranged, if have, illustrate that then this port link is normal, otherwise illustrate that the link of this port may be for intersecting misconnection.
There is following open defect in such scheme: for first kind of scheme, because cable uses wearing and tearing for a long time, the numbering of its interface side can not or be difficult to identification sometimes, bring very big difficulty for artificial detection checking work, even the numbering of its interface side can be recognized, also very low by the efficient of manually carrying out detection and location, but also inevitably be subjected to the restriction of human error.For second kind of scheme, need manually to issue data and send order, and the testing of each port can not walk abreast and carry out at each port, can only serial process, thereby detect complex steps, inefficiency.
Summary of the invention
In view of this, the invention provides a kind of method that detects link intersection misconnection, need not manually to participate in testing process, only need an order can detect link automatically and whether have the intersection misconnection.
Further aim of the present invention is: the definite numbering of obtaining the misconnection port.
Technical scheme of the present invention is achieved in that in order to achieve the above object
A kind of method that detects link intersection misconnection, the end that every link to be measured is set is an outloop, this method is further comprising the steps of:
A, all link other end corresponding port to be measured send data command by one and trigger simultaneously the detection data that outwards transmission has current port number information;
The port that b, each transmission detect data at first judges whether to receive looping back data, if not, then provide the information of not receiving data, if, judge respectively more then whether the detection data that send separately are identical with port number information in the looping back data that receives, if identical, then the wiring of this port link is normal, otherwise, the wiring error of this port link.
Preferably, described step b further comprises: when detection data that send and the port number information in the looping back data that receives are inequality, obtain the definite port numbers of misconnection port according to the port number information in the looping back data that receives.
Use the present invention, may occur the port of link intersection misconnection or the port that all need be tested on the Devices to test and be set to outloop, and after making the outside simultaneously transmission of corresponding each port that connects with it have the detection data of port information, receive this looping back data, whether the port information in sending data and receive data by contrast then is identical, whether the link wiring that detects this port is correct, port for the link wrong, can obtain the definite numbering of wrong port according to the port information that receives in the data.The present invention can be widely used in the communication apparatus multilink being detected simultaneously, and is convenient, fast, efficient.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further details.
Thinking of the present invention is: at first, the equipment end of sending out the detection data that setting links to each other with link to be measured is a local terminal equipment, its other end is an opposite equip., and it is outloop that the port that needs on the opposite equip. to test is set, and the port that needs here to test is the port that links to each other with local terminal equipment on this equipment; Secondly, all of the port of an order detection data equipment sends simultaneously under the control of a transmission data command and has the detection data of port information and receive looping back data.Then, the data that send are compared with the looping back data of reception, determine the link of intersection misconnection.
Figure 2 shows that the link wiring schematic diagram when using the present invention detects, for detecting the link of intersection misconnection, the present invention takes following steps:
1) port that links to each other with local terminal equipment in the opposite equip. being set is outloop; Here, all ports that links to each other with local terminal equipment all can be set to outloop, also the part port that can only be provided with wherein is an outloop;
2) all of the port of local terminal equipment sends under the control of ordering at one, outwards sends the detection data that have the local terminal port information simultaneously;
3) all ports that link to each other with opposite equip. will receive separately port respectively through the data of opposite equip. loopback in the local terminal equipment;
4) each port that receives looping back data compares the data that send and the data of reception respectively in the local terminal equipment, if the port information that receives in the data is identical with port information in sending data, illustrates that then the link of this port connects normally; If the port information in the reception data is inequality with the port information that sends in the data, then judges this port and which port formation and intersect misconnection according to receiving port information in the data.
Because the opposite equip. port that links to each other with local terminal equipment all of the port not necessarily all is set to outloop, therefore, though all of the port of local terminal equipment outwards sends data simultaneously, but the port that is not each transmission detection data can both be received looping back data, so local terminal equipment only compares judgement to the port that receives looping back data, does not receive that the port of looping back data provides the information of not receiving data.
As shown in Figure 2, the port 0 (PORT0) in the local terminal equipment sends and has the data of information 0, and also contains information 0 in the looping back data that receives, and illustrates that then this port wiring is correct; Port one in the local terminal equipment (PORT1) sends and has the data of information 1, and contains information 2 in the looping back data that receives; Port 2 (PORT2) in the local terminal equipment sends and has the data of information 2, and contains information 1 in the looping back data that receives, and illustrates that then the situation of misconnection all appears intersecting in port one and port 2; Port 3 (PORT3) in the local terminal equipment sends the data that have information 3, because the loopback setting is not done in the corresponding port of the opposite equip. that is connected with this port, so the port 3 in the local terminal equipment can not received looping back data, has to not receive the information of data.Can conclude that according to the loopback information that each port receives the port one of local terminal equipment has been received on the port 2 of opposite equip., the port 2 of local terminal equipment has been received on the port one of opposite equip..Like this, can detect the link of many misconnection in the communication apparatus fast, efficiently simultaneously.
In addition, under the control of system, local terminal equipment can have only several ports of appointment to send detection information, rather than all of the port sends detection information simultaneously.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
