    摘要: A circuit for protecting lines such as telephone lines against positive or negative overvoltages having respective determined minimum values (+V1 and -V2). Between a common point (C) and a first conductor (A), a second conductor (B) and ground (M), are inserted first, second and third protection components, respectively constituted by a diode (D1, D2, D3) in anti-parallel with a thyristor (T1, T2, T3), the anode of which is connected to the common point and the gate of which receives a polarization signal. The first and second thyristors are of the cathode-gate type and the third (T1) of the anode-gate type. Each of the first and second thyristors is associated with a transistor (TR2, TR3). The emitter of each transistor is connected to the gate of the corresponding thyristor and the collector of each transistor is connected to a second common point (D) connected to the gate of the third thyristor.

    摘要: A system and method is described that enables autonomic discovery of wireless network security mechanisms by mobile devices. Stateful monitoring of wireless devices facilitates identification of pending network connectivity loss, enabling a handoff server to proactively advertise new points of access and their associated security mechanisms to devices before connectivity is lost. As a result, devices may seamlessly transition between secure networks. Stateful monitoring of device reachability may be used together with device certificates and/or tokens to decrease the potential of MAC spoofing and further secure the network. Stateful monitoring of device connectivity status during network transitions facilitates the identification of rogue access points. The token or certificate on the device may be used to authenticate the device while transitioning between networks by a centralized entity, managing the initiation and the execution of the handover for the device.

    摘要: A method and a protection switching arrangement for protection switching of any one of a plurality of optical signals of a multi-wavelength optical signal from the failure of an optical component is provided. The multi-wavelength optical signal which contains the optical signals is itself rerouted by the use of wavelength agnostic rerouting elements, after which a tunable optical filter is used to obtain from the multi-wavelength optical signal the particular optical signal which would have been affected by the failure. In embodiments of the invention where the failed component is a switching fabric, the multi-wavelength optical signal is rerouted away from the failed switching fabric through a redundant switching fabric after which the particular optical signal is obtained with use of the tunable optical filter.
