<p>An embodiment of the present invention provides a method for data acquisition. The method includes the following steps: transmitting a request message for acquiring line parameters to a central-office end access apparatus, and obtaining a time T1 when the line parameter acquisition is started; receiving line parameter information reported by the central-office end access apparatus, and obtaining a time mark T2 of a line; and comparing the time T1 with the time mark T2 of the line, and saving the received line parameter information if the time T1 is larger than the time mark T2 of the line. Embodiments of the present invention further provide an apparatus and a system for data acquisition. Through the above solutions, the problem that the line parameter acquisition in a digital subscriber line system cannot meet requirements of system maintenance is solved.</p> |
