Embodiment Construction

[0031]As shown in Figure 2, the test plug KA introduces the DSLAM signal into the test box C through D0-D7 of the terminal board A. The 8 xDSL MODEM circuit boards in the test box C are synchronized with the start signal of the corresponding port of the DSLAM at the same time. After the board detects the synchronization signal, the 8 xDSL MODEM circuit boards will automatically enable the built-in dial-up software (the account number is input by the tester in advance, and it only needs to be input once to save when starting to use, and the account number is a multi-user account), these 8 xDSL MODEM The circuit board enables the address translation function (proxy Internet access function), which can translate the private network IP address of the notebook computer connected to the xDSL MODEM circuit board, so that users can access the Internet. The 8 xDSL MODEM circuit boards are aggregated to the small switch in the test box through the network cable, and the small switch is ...

Abstract

The quick detection device for DSLAM ports includes N pieces of 8 routes testing plugs (N8TP), testing cable, notebook computer (NC), and testing case. 8XN pieces of xDSL MODEM circuit board, and one switching exchange with multiple ports are setup inside the case. Through testing cables, phone lines of the said board are connected to N8TP respectively, and data lines of the said board are connected to 8XN pieces of data ports on the switching exchange. The other one data port on the switching exchange is connected to network port of NC. Using 8 routes testing plugs can accomplish quick connecting to 8 pieces of DSLAM ports in high efficiency. Then, using program stored in NC accomplishes testing in batch. When N is 1, the device can test 8 pieces of DSLAM ports within 1 minute. Thus, comparing current method, the invention raises testing speed for 8 times; moreover, N can be selected as 2 or 3 etc. The invention is suitable for telecom company to check, accept and maintain work.

Description

technical field [0001] The invention relates to a test device for the port performance of a DSLAM (Digital Subscriber Line Access Multiplexer), which is suitable for quickly detecting whether the port of the DSLAM is available on an MDF (distribution frame) frame in a computer room of a telecommunication company. It belongs to the field of digital information transmission. Background technique [0002] At present, xDSL (Digital Subscriber Line) broadband Internet access technology has been widely used by domestic fixed-line telephone users. The xDSL access technologies currently used for broadband access mainly include ADSL (Asymmetric Digital Subscriber Line) / ADSL2+ (Asymmetric Digital Subscriber Line 2+), VDSL (Very High Speed ​​Digital line) three techniques. DSLAM (Digital Subscriber Line Access Multiplexer), as a digital subscriber line access aggregation device, can provide users with high-speed broadband access with different technologies according to user needs and...
