Patent number: 8670525Abstract: A method includes identifying one or more second digital subscriber lines from one or more first digital subscriber lines based on historical performance data. The one or more second digital subscriber lines are identified based on degraded performance that is determined using first performance information for the one or more first digital subscriber lines. The method includes applying a line profile to the one or more second digital subscriber lines. The method includes storing second performance information associated with the one or more second digital subscriber lines. The method includes sending information to a remote computing device.Type: GrantFiled: March 13, 2013Date of Patent: March 11, 2014Assignee: AT&T Intellectual Property I, L.P.Inventors: Baofeng Frank Jiang, Xidong Wu, Jim Tidashi Otsuka, John Porter Van Slyke

Patent number: 8451978Abstract: A method includes selecting a first set of digital subscriber lines (DSLs) supported by a digital subscriber line access multiplexor (DSLAM). The DSLs of the first set exhibit reduced performance based on historical performance data. The method includes sending a request to the DSLAM for a first performance parameter for each of the DSLs of the first set. The method includes receiving the first performance parameters. The method includes removing DSLs from the first set that have suitable performance based on the first performance parameters to create a second set of DSLs. The method includes selecting a line profile to apply to the second set of DSLs. The method also includes sending a second request to the DSLAM to apply the line profile to the DSLs of the second set and then to determine a second performance parameter for each of the DSLs of the second set.Type: GrantFiled: February 25, 2011Date of Patent: May 28, 2013Assignee: AT&T Intellectual Property I, L.P.Inventors: Baofeng Frank Jiang, Xidong Wu, Jim Tidashi Otsuka, John Porter Van Slyke
