Abstract: Disclosed is a technique for managing access by a portable device to an in-vehicle router system (IVRS). The IVRS determines network access privilege of the portable device located within the vehicle. The portable device determines whether it is connected to a wireless access point (AP) of the IVRS or a rogue network. The portable device transmits a first token to the wireless AP, via a first communication link implementing a first protocol stack, to prompt the wireless AP to reply with a second token. The portable device receives the second token via a second communication link implementing a second protocol stack different than the first protocol stack between the portable device and the IVRS. The portable device determines whether the second token matches the first token. If the second token is determined to match the first token, the portable device authenticates the wireless AP.

Abstract: Disclosed is a technique for managing communications of portable devices within a vehicle through an in-vehicle router system. The in-vehicle router system includes a plurality of out-of-band interfaces used to determine a user type associated with a portable device used to manage a connection with a wireless access point. The out-of-band interface receives a query from a portable device via a first communication link. The query includes identifying information of the portable device and a request for network credentials to a second communication link with a wireless access point. A user type is determined based on a location of the out-of-band interface and a unique identifier. Network credentials associated with the determined user type are retrieved. The network credentials are provided to the portable device via the first communication link. Access to the second communication link is restricted based on the user type and/or vehicle status information.

The in-vehicle router system includes a plurality of out-of-band interfaces used to determine a user class associated with a portable device used to manage a connection with a wireless access point.

Abstract: A frequency domain reflectometry-based bridged tap detection system for a telecommunication wireline employs a prescribed filtering operator, such as a ‘best-fit’ curve filter or a piecewise high pass filter bank, upstream of a Fourier processing operator, to improve the signal-to-noise ratio of the digitized amplitude array of the swept frequency band. To fit the response tones within the dynamic range of the analog-to-digital converter that digitizes the response tones detected from the wireline, a signal conditioning circuit, comprised of a comb filter bank, envelope detector and compander, is installed between the test head and the input to the analog-to-digital converter.
