Abstract
Summary form only given, as follows. An analog telephonic network modernization system is equipped with a DSP subsystem capable of all functions of an R2 transceiver. Elliptic filters and adaptive threshold detection are adopted to handle noise and impedance mismatch problems associated with relay tracking. A brief study of actual MFC protocol based on autoregressive spectrum modeling is also presented
