Problems solved by technology

On the one hand, the price of the test head is relatively expensive, and the equipment cost is too high for one line grab matrix and one test head; on the other hand, the total subscriber lines of a single DSLAM generally do not exceed 1000 lines
A test head maintains 1000 lines, the utilization rate is obviously too low
Therefore, for this solution, the equipment cost and maintenance cost are too high for operators, especially when implementing online testing on a large scale

Embodiment Construction

[0041] As shown in Figure 1, the cascaded on-line test system of the present invention comprises the following parts: test terminal (Test-Client, be called for short TC), test server (Test-Server, be called for short TS), grab line matrix (TAMTest-Access-Matrix, TAM for short) group (TAM Group for short, TAMG for short), line grasping matrix group information system (TAMG DataBase, short for TAMG-DB), test head (Test-Head, short for TH). TAMG refers to a group of TAMs that are physically close (generally in the same computer room), and are cascaded through the test bus (the solid line in the figure). Through the test bus, all TAMs of TAMG are connected to a test head and share a test head. If there are multiple pairs of test buses in the test bus, they can also be connected to one or more test heads. Through the context information of the wire grab matrix saved in the wire grab matrix information system, the test server can effectively control the grab matrix to ensure that no...

Abstract

The system includes test server, test terminal, information system of matrix group for grasping wire, matrix group for grasping wire, and test head. The matrix group for grasping wire includes one or more matrices for grasping wire. Through multiple test buses each matrix can be cascaded. Using context information of matrix saved in information system of matrix group for grasping wire, the test server can control matrix effectively so as to guarantee that multiple pairs of wire will not be grasped by a pair of test bus at same time, and one matrix group for grasping wire shares a test head to carry out test. The invention reduces cost of system device, cost for building network, and maintenance cost effectively.

Description

technical field [0001] The invention relates to an on-line test system and a test method of an access node of an access network, in particular to a cascaded on-line test system and a test method thereof. Background technique [0002] As ADSL is used in a large area, a thorny problem that operators face is how to effectively maintain the access network. In small-scale cases, the manual method is the traditional operation and maintenance mode of operators. This method has the obvious defect of high operating cost, especially in a large-scale operating environment. One of the ways to effectively reduce operation and maintenance costs is to use an automatic online test system. [0003] The basic principle of the online test system is to transfer the physical line to the test head by using the physical device (such as a relay) on the control access point; then, the test head can test the line and judge the functional components of the access network ( Including: modem, loop li...
