Latest Patents

Neigh holds a patent for an "Electronic loaded/nonloaded telephone loop identification circuit." This innovative circuit identifies loaded and nonloaded customer telephone loops. The ability to segregate these loops allows for the use of separate balance networks in hybrid circuits that connect customer loops to a digital switching office. By implementing separate balance networks for loaded and nonloaded loops, the singing margin on those loops is improved. The circuit features an impedance measuring component that assesses the real part of the impedance of a connected loop, comparing it to a reference signal. If the real part of the loop impedance exceeds the reference signal, a loaded loop is identified. Conversely, if it is less, a nonloaded loop is recognized. Additionally, the circuit includes a self-calibrating arrangement that connects a reference impedance to the impedance measuring circuit, ensuring accurate loop identification.
