Problems solved by technology
[0002] In traditional SDH, the processing of DCC channels is generally one-to-one processing, that is, one DCC channel uses a group of DCC signal hardwires to connect the optical interface line card and the network management line card, which increases the back-end The connection of the board also limits the total number of DCC channel processing, which is not conducive to the large-capacity SDH system to manage more services

Embodiment Construction
[0024] In this bus-based DCC processing system, the arrows indicate the flow of DCC data in the system. In order to test the correctness of the entire DCC signal, the following four stages of testing are required.
[0025] Now describe the flow process of the present invention with reference to accompanying drawing 4. First, after the test starts, enter the first test stage. If the test is unsuccessful, modify the module code in Figure 3 until the test is successful, and then enter the third test phase. If the test is unsuccessful, modify the interface between the module in Figure 3 and PMC7367 place code, test program code, check the module codes in attached drawings 1, 2, and 3 at the same time, until the test is successful, enter the fourth test stage, if the test is not successful, modify the software code, and check the modules in attached drawing 3 and PMC7367 The code at the interface, the module code in Figures 1, 2, and 3, until the test is successful. Indicates tha...

The present invention discloses a testing method based on a novel DCC processing technology. The testing method includes four steps: the first step, the DCC bus of the optical interface card performs a loopback hanged meter test itself; the second step, the loopback test after the DCC cross-assignment on the network element managing card is performed; the third step, the DCC data loopback test onthe optical circuit is performed by sending packages through BMU HDLC processing chip; the fourth step, normal network management program is used for observing the normality of the two stations for transmitting DCC data through DCC processing by the BMU of the two stations. The test in said four steps is not only favorable for searching problems but also determine the normality and stability of the working of novel DCC bus through testing the normality and stability of the novel DCC bus processing.
Description
technical field [0001] The invention relates to the technical field of synchronous digital sequence (SDH), in particular to a test method for data processing of data communication channel (DCC) channel in SDH. Background technique [0002] In traditional SDH, the processing of DCC channels is generally one-to-one processing, that is, one DCC channel uses a group of DCC signal hardwires to connect the optical interface line card and the network management line card, which increases the back-end The connection of the board also limits the total number of DCC channel processing, which is not conducive to the large-capacity SDH system to manage more services. Therefore, a bus processing method for DCC is proposed. This new DCC bus-based processing method can effectively reduce the interconnection lines on the backplane, and at the same time increase: the total number of DCC channel processing. For the previous DCC channel processing, a simple one-to-one interconnection process...
