Problems solved by technology

[0009] Repeated manual operations are required: configuring and deleting crossovers, connecting cables, changing the number of connections between test instruments and cables; E1 ports of PDH boards are prone to errors when connected in series with cables, which affects the accuracy of test results, and It is not convenient enough to eliminate connection errors; for SDH boards with more than 1 optical port and higher STM-N rate level, the efficiency improvement is not obvious

Embodiment Construction

[0038] The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

[0039] In order to solve the problems existing in the prior art, the embodiment of the present invention provides a method for detecting SDH boards, such as Figure 5 As shown, the method includes:

[0040] Step 501, according to the number of E1 ports of quasi-synchronous digital series PDH boards and the number of low-order virtual containers of the measured synchronous digital series SDH boards, configure the connection between the E1 ports of the PDH boards and the low-order virtual containers of the tested SDH boards The cross-connection and the cross-connection of the auxiliary SDH board itself form a loop; among them, the last unconfigured low-order virtual container of the auxiliary SDH board is set as the time s...

Abstract

The invention relates to the technical field of communication and particularly relates to a method, a device and a system for detecting an SDH (Synchronous Digital Hierarchy) card. The detected SDH card is in cross connection with a PDH (Pseudo-synchronous Digital Hierarchy) card and an auxiliary SDH card, so as to form a pseudo-random sequence transmission loop for a user, and then a pseudo-random sequence is sent to detect whether the configured cross connection can work normally or not; a traditional PDH card E1 port serial connection mode is changed, so that the practical connection operation is simpler and more definite and is less prone to error, and wire cable fault can be excluded more conveniently; and simultaneously manpower is greatly saved, and the test efficiency is improved.

Description

technical field [0001] The invention relates to the technology in the communication field, in particular to a method, device and system for detecting SDH boards. Background technique [0002] In the process of research and development, system testing, production and delivery, etc., it is inevitable to perform a traversal test of the V12 time slot and the occupied backplane bus on the SDH (Synchronous Digital Hierarchy, synchronous digital series) single board or SDH system. For SDH boards, different optical port rates correspond to different numbers of services. The higher the rate, the greater the number of corresponding services. If the rate of the optical port is STM-N, the corresponding number of services is: 63*N. It can be seen that the service traversal test on the SDH board requires a very large number of services to be tested. According to the traditional test method, it is necessary to continuously replace the number of service channels and configure the time slo...
