[0094] To facilitate the understanding of the above technical solution of the present invention, the above technical solution of the present invention will be further described from the perspectives of architecture and principle as follows:

[0095] The present invention quickly extracts the data in the TDM signal and inserts and forwards the custom time slot in real time. At the receiving end, by determining the boundary of each time slot of the TDM signal, the data of each time slot in the signal is extracted one by one, which is convenient for further protocol analysis; at the sending end, according to the protocol parsed by the receiving end, several time slots can be inserted for real-time forwarding according to the application. According to the Figure 4 process, the specific steps are as follows:

[0096] Step 1. According to the Figure 5 process, observe the signal with an oscilloscope to determine the relevant parameters such as the signal coding rule and coding rate. After measurement: The signal follows the Manchester code coding rule. That is, when the encoded signal changes from 0 to 1, it means that the value before encoding is 1, and when it changes from 1 to 0, it means that the value before encoding is 0. The steps are as follows: 1) Set the parameters such as the time base and vertical scale of the oscilloscope, and measure the parameters such as the signal jump time and pulse width; 2) Observe that there is a jump in the middle of each code element measured, and the jump time interval is relatively stable, then it can be determined that the signal follows the Manchester code coding rule; 3) Measure the relevant parameters of the signal. After measurement, the coding rate is 32 Mbps, the frame length is 10.0625 us, the period is 156.25 us, and the time slot interval is 187.5 ns.

[0097] Step 2. Extract the data. Convert the Manchester code into binary numbers and organize them into 16-bit data for further analysis of the data.

[0098] Step 3. According to the Figure 6 process, analyze the data and analyze the protocol. After analysis, the data of this TDM signal has the following characteristics:

[0099] 1) The data follows the Little-Endian format and the LSB (Least Significant Byte) is sent first.

[0100] 2) The TDM message data frame structure is as Figure 7 shown below. Specifically: start bit (1 bit before encoding, value is 1) + start word (high byte is the time slot number, low byte is the number of data) + INDEX word (incremented by itself according to the number of data frames) + 8 data words (user data) + CRC check (Cyclic Redundancy Check) bit (the polynomial is CRC16-CCITT-FALSE).

[0101] The steps are as follows: 1) Collect a large amount of data through step 2; 2) Try to organize the data according to the big (little) - endian format and high (low) - byte method. After achieving the goal of regular continuous frames, it can be determined; 3) Decode the organized data according to the logic of start bit, end bit, packet header, and packet tail (check word). Search for key data such as time slot number, length, and number of frames; 4) Determine the check method. Observe the data according to CRC (Cyclic Redundancy Check), parity check, sum check, etc. Different check methods have certain rules for the length of the check field. For example, the parity check generally only requires 1 bit; the check field length of CRC-8 check is 1 byte; the check field length of CRC-16 check is 2 bytes; the check field length of CRC-32 check is 4 bytes. According to the check field length, it can be initially speculated that the check method is CRC-16. Subsequently, use different CRC generation polynomials for online calculation, compare the calculation results with the check field in the data frame, and finally determine that the check method is: CRC16-CCITT-FALSE. 5) Analyze and organize the data in large quantities according to the initially confirmed protocol to determine the final protocol.

[0102] Step 4: Check the self - defined generated signal parameters. According to the data protocol and rules analyzed in step 3, generate the processing logics for the receiving end and the sending end, and loop - back test the accuracy of the data (protocol, rate, frame length, period). If the loop - back detection between the sending end and the receiving end is correct and the signal parameters of the sending end are the same as those in step 1, it means that the self - defined generated time slots are indistinguishable.

[0103] Step 5: According to the Figure 8 process, insert the time slots generated in step 4 into the original time slots to generate TDM message data. Utilize the concurrent processing ability of FPGA (Field Programmable Gate Array, a programmable logic chip) to parse the last time slot number of the received TDM signal at the receiving end, thereby determining the time slot number to be inserted and generating the time slot message to be inserted, and simultaneously generating the message data after insertion.

[0104] Step 6: Convert the inserted data into Manchester code to generate the merged TDM signal. Then, in accordance with S4, connect the merged TDM signal to the receiving end and perform loopback detection. Successful detection indicates that the generated message after merging is error-free.
