The OSU (Optical Service Unit) technology is an innovative technology based on the OTN kernel. The OSU signal is encapsulated in the OTN signal and belongs to the customer layer of the OTN signal.

[0003] At present, there is a demand for OSU signal degradation testing. The alarm reporting and protection switching function test triggered by the OSU signal degradation rely on the error code down insertion technology, and the signal degradation condition is tested by the down insertion error rate.

Since the forward error correction (FEC) function cannot be turned off, it is difficult to trigger the signal degradation alarm, and the OSU technology is sensitive to the error code amount, which affects the test efficiency and the reliability of the test results.

[0049] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0050] Referring to Figure 1 is a flow diagram of a bit error quantitative insertion method of the OSU signal provided in the embodiment of the present application. The embodiment of the present application provides a bit error quantitative insertion method of the OSU signal, which is specifically executed through the following steps S11 to S13.

[0051] S11, network connection is performed between a signal source single board and an OTN test instrument;

[0052] S12, after the network connection, the signal source single board is controlled to create an OSU service to generate an OSU signal;

[0053] S13, a preset parameter configuration instruction is sent to the OTN test instrument to control the OTN test instrument to quantitatively insert a bit error into the OSU signal.

[0054] In the embodiment of the present application, in order to realize the degradation test of the OSU signal, the OSU signal needs to be inserted with a bit error to simulate signal degradation. The embodiment of the present application mainly inserts a Bit All bit error in a quantitative manner through a wave division side OTN test instrument. The Bit All bit error insertion mainly inserts a bit error into an OTN code stream according to a selected bit error rate, and the payload of the OTN is inserted to be bad, so as to simulate signal degradation.

[0055] In the specific application process, refer to Figure 2 Fig. 1 is a schematic diagram of network connection of a signal source single board and an OTN test instrument in an embodiment of the present application, and the signal source single board and the OTN test instrument are connected in network, wherein the signal source single board is mainly used for configuring OSU service to generate OSU service signal; the OTN test instrument is mainly used for realizing error code under plug.

[0056] Refer to Figure 3 Fig. 2 is a first principle schematic diagram of error code quantitative under plug of OSU signal in an embodiment of the present application, after the signal source single board and the OTN test instrument are connected in network, EoOSU service is created from the signal source single board to generate OSU signal, then ODUk error code is quantitatively under plugged at the output port of the OTN test instrument, the instrument changes OPUk payload, which is equivalent to changing the overhead and payload of the OSU signal. The realization of the quantitative error code under plug process of the OTN test instrument is that corresponding parameter configuration instruction is input to the OTN test instrument, so that the OTN test instrument quantitatively under plugs error code to the OSU signal according to the configured parameters, so that the under plugged error code reaches the target error code rate.

[0057] As an example, taking the OTN test instrument as VIAV1601 instrument, the instrument configures under plugged ODU-AIS alarm, the instrument will modify the ODU payload to all 1, then the OSU frame carried in the ODU payload will also be modified to all 1, so as to realize under plugged OSU frame error code, at the same time, the under plug is configured in the mode of Continuous Burst, the proportion of the frame number with AIS alarm and the frame number without AIS alarm is configured, so as to realize quantitative under plugged error code. For example, an ODU2 is 10G bandwidth, and 10M OSU channel is under hung, the instrument is configured with AIS, if the proportion of the frame number with AIS alarm and the frame number without AIS alarm is 1:1, then the error code rate is 50%, and the OSU under hung by the ODU can be considered as under plugged with 50% error code.

[0058] Preferably, before the step S13, that is, the step of sending the preset parameter configuration instruction to the OTN test instrument to control the OTN test instrument to quantitatively under plug error code to the OSU signal, the method further comprises the step S14:

[0059] The preset mode configuration instruction is sent to the OTN test instrument to control the OTN test instrument to be in the pass-through mode.

[0061] Preferably, after the steps S11 to S13 are performed, the method further comprises a step S15:

[0062] S15, when the OTN test instrument quantitatively inserts the error code to reach the target error code rate, performing the degradation test on the OSU signal.

[0063] In the embodiment of the application, the OSU error code detection is defined in the standard, and the OSU has rich overheads for indicating the on-off and good-bad of the service signal, wherein the error code information is contained. The target error code rate is set in advance, the OTN test instrument is used to quantitatively insert the error code to the OSU signal, and when the inserted error code reaches the target error code rate, it indicates that a certain degradation scene of the OSU signal is simulated, the degradation test on the OSU signal is realized, and the OSU error code is quantitatively measured.

[0064] By using the technical means of the embodiment of the application, for the degradation test scene of the OSU service signal, the existing OTN test instrument is used to quantitatively insert the error code to the OSU signal created and emitted by the signal source single board, the problem that the noise is added to the line side of the OSU signal to cause the error code amount control difficult and affect the degradation test precision of the OSU signal is avoided, the OSU signal error code amount can be quantitatively inserted by using the scheme of the application, the scene that the OSU signal is sensitive to the error code amount can be well coped with, the test precision of the OSU signal is improved, and the whole process is simple and convenient to operate.

[0065] As a preferred embodiment, the embodiment of the application is further implemented on the basis of the above-mentioned embodiment, after the signal source single board and the OTN test instrument are connected in networking, the method further comprises:

[0066] The test single board is connected in networking with the OTN test instrument;

[0067] After the OTN test instrument quantitatively inserts the error code to the OSU signal is controlled, the method further comprises:

[0068] The test single board detects the error code rate of the OSU signal is controlled;

[0069] When the error code rate of the OSU signal detected by the test single board is the target error code rate and is the same as the error code rate quantitatively inserted by the OTN test instrument, it is determined that the error code quantitatively inserted by the OTN test instrument reaches the target error code rate.

[0070] That is, under the preferred embodiment of the application, the OSU signal error code quantitatively inserting method is specifically performed through the following steps S21 to S25:

[0071] S21 connects the signal source single board and the OTN test instrument in network, and connects the test single board and the OTN test instrument in network;

[0072] S22, after the network connection, the signal source single board creates OSU service to generate OSU signal;

[0073] S23, the preset parameter configuration instruction is sent to the OTN test instrument, so as to control the OTN test instrument to quantitatively insert error code to the OSU signal;

[0074] S24, the test single board detects the error code rate of the OSU signal;

[0075] S25, when the error code rate of the OSU signal detected by the test single board is the target error code rate, and the error code rate inserted quantitatively by the OTN test instrument is the same, it is determined that the error code inserted quantitatively by the OTN test instrument reaches the target error code rate.

[0076] In the embodiment of the application, referring to Figure 4 , it is the schematic diagram of the network connection of the signal source single board, the OTN test instrument and the test single board in the embodiment of the application, the signal source single board, the OTN test instrument and the test single board are connected in network, wherein the signal source single board is mainly used for configuring OSU service to generate OSU service signal; the OTN test instrument is mainly used for realizing error code insertion; the test single board is mainly used for testing the error code rate in the OSU service signal transmitted from the signal source single board, that is, enabling error code performance monitoring.

[0077] Referring to Figure 5 and Figure 6 , Figure 5 , it is the second principle schematic diagram of the quantitative error code insertion of the OSU signal in the embodiment of the application, Figure 6 , it is the third principle schematic diagram of the quantitative error code insertion of the OSU signal in the embodiment of the application, after the network connection of the signal source single board, the OTN test instrument and the test single board, EoOSU service is created from the signal source single board, thereby generating OSU signal, then the OTN test instrument is set to the through mode, and the corresponding parameter configuration instruction is input to the OTN test instrument, thereby quantitatively inserting error code to the OSU signal at the output port of the OTN test instrument.

[0078] Further, the error code scene is tested on the test single board according to the error code test method defined by the OSU standard, that is, the error code rate in the OSU signal transmitted from the signal source single board is detected by the test single board. The error code rate of the OSU signal detected by the test single board is compared with the error code rate quantitatively inserted by the OTN test instrument. When the error code rate of the OSU signal detected by the test single board is the same as the error code rate quantitatively inserted by the OTN test instrument, it is indicated that the test method of simulating the OSU signal degradation by the OTN instrument is feasible, and the error code quantitatively inserted by the OTN test instrument can be realized. Moreover, the error code rate of the OSU signal detected by the test single board is the preset target error code rate, and then the subsequent degradation test of the OSU signal can be performed.

[0079] By using the technical means of the embodiment of the present application, for the degradation test scene of the OSU service signal, the error code insertion of the OSU signal created and transmitted by the signal source single board is performed by the existing OTN test instrument, and the feasibility and accuracy of the error code insertion result are detected by the test single board. The embodiment of the present application can realize the quantitative insertion of the error code amount of the OSU signal, can better cope with the scene that the OSU signal is sensitive to the error code amount, improves the test accuracy of the OSU signal, and the whole process is simple and convenient to operate.

[0080] As a preferred embodiment, the embodiment of the present application is further implemented on the basis of the above-mentioned embodiment, and the networking connection of the signal source single board and the OTN test instrument comprises:

[0081] determining whether the interface formats of the signal source single board and the OTN test instrument are the same;

[0082] when the interface formats of the signal source single board and the OTN test instrument are different, selecting a corresponding first OTN auxiliary single board according to the interface formats of the signal source single board and the OTN test instrument;

[0083] networking connecting the signal source single board and the OTN test instrument through the first OTN auxiliary single board;

[0084] when the interface formats of the signal source single board and the OTN test instrument are the same, directly networking connecting the signal source single board and the OTN test instrument.

[0085] The networking connection of the test single board and the OTN test instrument comprises:

[0086] determining whether the interface formats of the OTN test instrument and the test single board are the same;

[0087] when the interface format of the OTN test instrument and the test single board is different, according to the OTN test instrument and the test single board, a corresponding second OTN auxiliary single board is selected;

[0088] the OTN test instrument and the test single board are connected in network through the second OTN auxiliary single board;

[0089] when the interface format of the OTN test instrument and the test single board is the same, the OTN test instrument and the test single board are directly connected in network.

[0090] It should be noted that not all wave division side board cards supporting OSU service support docking with the OTN test instrument, so the ODUk / OSU signal can be converted and bridged by using the board card supporting docking with the instrument. The conversion and bridging mode includes various scenes, and the general principle is to transmit the ODUk signal and the OSU signal, and the OTN test instrument can be transmitted according to the selected overhead level, so as to achieve the purpose of adding noise to the OSU signal through the OTN test instrument.

[0091] In the embodiment of the application, when the signal source single board and the OTN test instrument cannot be directly docked, a first auxiliary single board capable of being docked with the signal source single board and the OTN test instrument at the same time is selected to bridge, the signal source single board is connected with the first auxiliary single board, and then the first auxiliary single board is connected with the OTN test instrument, so as to realize the network connection of the signal source single board and the OTN test instrument.

[0092] Similarly, when the OTN test instrument and the test single board cannot be directly docked, a second auxiliary single board capable of being docked with the OTN test instrument and the test single board at the same time is selected to bridge, the OTN test instrument is connected with the second auxiliary single board, and then the second auxiliary single board is connected with the test single board, so as to realize the network connection of the OTN test instrument and the test single board.

[0093] Optionally, the embodiment of the application mainly judges whether the interface format of the single board and the OTN test instrument is the same through the OTU rate. Specifically, the OTU rate supported by the single board and the OTU rate supported by the instrument may be consistent or inconsistent. When the OUT rates supported by the two are inconsistent, it indicates that the interface formats of the two are different, and the auxiliary single board is needed for bridging.

[0094] The judgment whether the interface format of the signal source single board and the OTN test instrument is the same includes:

[0095] judging whether the OTN rate supported by the signal source single board and the OTN rate supported by the OTN test instrument is consistent.

[0096] If yes, it is determined that the interface format of the signal source single board and the OTN test instrument is same; if no, it is determined that the interface format of the signal source single board and the OTN test instrument is different.

[0097] Similarly, the judging whether the interface format of the OTN test instrument and the test single board is same comprises:

[0098] Judging whether the OTN rate supported by the OTN test instrument and the OTN rate supported by the test single board is consistent;

[0099] If yes, it is determined that the interface format of the OTN test instrument and the test single board is same; if no, it is determined that the interface format of the OTN test instrument and the test single board is different.

[0100] Referring to Figure 7 , it is a schematic diagram of conversion bridging by an auxiliary single board in the embodiment of the application, as an example, it is assumed that the signal source single board and the test single board only support OTU1 rate, and the OTN instrument only supports OTU2 rate, at this time, direct docking is not supported, and therefore, the OTN auxiliary board needs to be added in the middle of the single board and the OTN test instrument to convert OTU1 to OTU2, the OTU1 signal sent by the signal source single board is mapped into the OTU2 signal, and then the OTN test instrument is docked, and similarly, the OTU2 signal sent by the OTN test instrument is mapped into the OTU1 signal, and then the test single board is docked.

[0101] Referring to Figure 8 , it is a fourth principle schematic diagram of quantitative under insertion of error code of an OSU signal in the embodiment of the application, for the scene that the signal source single board, the test single board and the OTN test instrument do not support docking, the auxiliary single board is used to realize networking connection of the signal source single board, the OTN test instrument and the test single board, then the EoOSU service is created from the signal source single board to generate the OSU signal, then the OTN test instrument is set to a through mode, and then the corresponding parameter configuration instruction is input to the OTN test instrument, so that the error code is quantitatively under inserted to the OSU signal at the output port of the OTN test instrument, finally, the test single board is controlled to detect the error code rate in the OSU signal transmitted from the signal source single board, and when it is verified that the error code under inserted by the OTN test instrument reaches the target error code rate, the subsequent deterioration test on the OSU signal is performed.

[0102] By using the technical means of the embodiment of the application, the problem that the OTN test instrument and the signal source single board or the test single board cannot be directly docked is solved in a conversion bridging manner, and the smooth performance of the deterioration test on the OSU signal is further ensured, and good universality is achieved.
