2-Wire Baseband Modem
Overview
V-DSU558 is a high-performance 2-wire full duplex base-band modem based on DSP and LSI technology. DSU558 is applied on DDN or FR line. It has high quality transmission (transmission distance can reach 3Km on 0.5mm line) due to the three reasons: adapts digital DSP to achieve echo cancellation, adaptive equal technology and high-performance 4B3T line code technology. With good transmission characteristic, the transmission distance can be up to 3Km on 0.5mm line. This device complies with line features of ANSI 15 loopback test regulations; it also meets the China Post & Telecommunication Department's requirements on line transmission.
