Abstract:

A telephone line test system that may be used to compute line length of subscriber lines connected to a central office or other distribution point. When initially installed, the test system may automatically compute CO limits. The CO limits are computed from single-ended measurements on subscriber lines and represent electrical effects of the path between a test head and the distribution point. These CO limits are used to more accurately compute the length of lines connected to the distribution point using measurements made by the test system. Because the process uses single-ended measurements, it may be run in background mode during the initial installation of the test system or at any subsequent time it is desired to update the CO limits.

Abstract:

Example implementations include a method, apparatus and computer-readable medium of controlling a security system by a computer device, comprising receiving device metadata associated with a device in communication with a wireless communication access point. The implementations further include determining that the device metadata comprises matched device metadata based on a match with one of a plurality of previously-identified device metadata in a historical database that stores the plurality of previously-identified device metadata in association with one or more of a plurality of security breach events and a corresponding one of a plurality of security breach probability values. Additionally, the implementations further include determining that the matched device metadata corresponds with a security breach probability value that exceeds a security breach probability threshold. Additionally, the implementations further include generating an alert and sending the alert to a security system device, wherein the alert is configured to initiate a security function.
