摘要： A broadband device of the central office end capable of self-detecting and a method for detecting the XDSL port, set at least one switch matrix control switch set to connect each CO port of the XDSL to the peripheral line of the remote user’s MODEM by the switch matrix of the control switch set; the control switch set receive the control command from the control system inside the device, then disconnect any port of the CO XDSL port according to the control demand, and exchange the connected peripheral lines of any two ports among the CO XDSL ports. Disconnect any two ports of the CO XDSL ports by control switch, or exchange the connected peripheral lines of any two ports among the CO XDSL ports. Therefore, when a faulty CO port is checked out, it can be replaced by the normal port inside the un-faulty device so as to detect the initial CPE peripherally connected the faulty port, thus it can be decided whether the faulty port is caused by the port itself or by the user end. The device and method can rapidly locate and judge the port fault without additional private testing system, therefore reduces the cost.
