Abstract

The invention provides a 2M communication detection method and detection device and is used for solving the problem that when the detection device detects a communication circuit, the excessive communication line load is liable to cause and the communication speed at two ends of the communication circuit is liable to reduce. The method and device relate to 2M data channel detection, particularly relate to non-loop 2M data channel detection. The method comprises the steps of S101, receiving data D by the detection device A and analyzing the data D, wherein the data D is E1 frame data; S102, inserting self-defined link protocol message data into an SA field of the data D, wherein the self-defined link protocol message data comprises a mark of the detection device A, and time information of receiving the data D by the detection device A; S103, packaging the data D into E1 frames and sending the E1 frames; and S104, receiving the data D by the detection device B and analyzing the received data D. The detection device can be connected with the communication circuit for a long time.

Description

technical field [0001] The invention relates to 2M data channel detection, in particular to non-loop 2M data communication detection. Background technique [0002] Digital transmission analyzer is the most powerful and reliable tool for daily maintenance work of telecom engineers and technicians. Currently, it supports conventional 2M and data channel bit error test functions, as well as test and analysis functions for 2M frame structure data, dual-channel E1 monitoring, loop delay, switching delay, output waveform, output jitter, and signal level. [0003] However, the cause of the failure of the data channel in reality is complicated, and the existing analyzer cannot test such as the transmission problem between two points on the path, so that the location of the faulty device or line cannot be determined. [0004] The 30-channel pulse code modulation PCM in Europe is referred to as E1, and the rate is 2M / s. A time-division multiplexing frame of E1 (its length T=125us) is...
