Embodiment 1

[0026] In this embodiment, the cable characteristics of each target port in the current link establishment state and the crosstalk coefficient between the ports are directly collected from the network element device, and the judgment is made based on the comparison between the collected information and the corresponding crossline threshold in the threshold database. Whether or not each target port is in-line does not require operators and maintenance personnel to carry out special external testing equipment to conduct on-site measurements on the cables, which can not only improve testing efficiency and convenience, reduce testing costs, but also improve testing accuracy.

[0027] The threshold database in this embodiment stores the correspondence between cable characteristics and cross-line thresholds, that is, different cable characteristics correspond to different cable types, and different cable characteristics in the threshold database correspond to a cross-line threshold, w...

Embodiment 2

[0053] This embodiment provides a cross-line detection device, and the cross-line detection device can be set in an operation and maintenance server (OMC, Operation and Maintenance Center). Figure 4 shown, including:

[0054] An information collection unit 401, configured to acquire a target port on the network element device that is in a link-building state, cable characteristics of each target port, and a crosstalk coefficient between each target port;

[0055] In this embodiment, one information collection unit may be used for one network element device. When targeting multiple network element devices, multiple information collection units can be used to run concurrently. The information collection unit 401 in this embodiment specifically includes various communication modules and storage modules. The communication module establishes communication with the network element equipment through corresponding communication protocols, and completes the collection of operating st...

Embodiment 3

[0073] This embodiment provides the operation and maintenance server OMC, see Figure 5 As shown, including a processor 51 and a memory 52, the processor 51 is used to control the modules in the memory (including but not limited to various software modules) to perform the following processes:

[0074] Obtain the target ports in the link-up state on the network element device, the cable characteristics of each target port, and the crosstalk coefficient between each target port;

[0075] Obtain the cross-line threshold corresponding to each target port cable from the threshold database according to the cable feature of each target port; the threshold database stores the corresponding relationship between the cable feature and the cross-line threshold;

[0076] Determine whether each target port is in cross-connection according to the crosstalk coefficient between each target port and the cross-connection threshold of each target port cable.

[0077] In this embodiment, the seri...

Abstract

The invention discloses a crosstalk detection method, device and operation maintenance server, which directly collects the cable characteristics of each target port in the current link building state and the crosstalk coefficient between each port from the network element equipment, and based on the collected information Comparing with the corresponding cross-wire threshold in the threshold database, it can be judged whether each target port is cross-wire. It does not require the operation and maintenance personnel to hold a special external detection device to measure the cable on the spot, which can not only improve the detection efficiency and convenience, but also It can reduce the detection cost, avoid the interference of artificial factors, and improve the consistency and accuracy of detection at the same time. It is especially suitable for realizing the automatic detection of the cross-wire situation of multiple network element device ports under the centralized management area.

Description

technical field [0001] The present invention relates to the field of broadband access network communications, in particular to a cross-line detection method, a device and an operation and maintenance server. Background technique [0002] In the actual application environment of the access network communication equipment, since the central office access equipment is directly connected to the enterprise and home users, the access network has a larger scale of user cable laying and a more difficult laying environment than the upper-layer transmission and core network. complex. Once a cable fault occurs, especially the cable string problem, it will seriously affect the user's service experience and needs to be dealt with immediately. At present, the usual practice is that operation and maintenance engineers use special external testing equipment to conduct on-site testing of user cables. The detection principle is basically based on the physical pulse method. There are problem...
