Abstract:
A mobile very high data rate digital subscriber line (VDSL) signal detector connectable to a telephone line coupled between a telecommunication device of a central office (CO) and user devices, the detector comprising:a case for enclosing all circuits and components; a microprocessor for controlling normal operations of all circuits; an input device coupled to the microprocessor for data input and test item selection; and a VDSL chipset coupled to the microprocessor and comprising circuit elements required for Internet connection; wherein when a test item is inputted through the input device, the microprocessor is activated to read the test item, in response an identification (ID) of the user device or the telecommunication device of the CO corresponding to the test item is written into the VDSL chipset for simulating a virtual one of the user device or the telecommunication device of the CO therein, to send a packet to the telecommunication device of the CO or the user device for test, and to determine whether there is a line interruption between the telecommunication device of the CO and the user device or a communication quality is poor based on a strength of a sent back signal from the telecommunication device of the CO or the user device.
