Overview
 

V-DSU558 is a high-performance 2-wire full duplex base-band modem based on DSP and LSI technology. Transmission rate ranges from 600bps to 128Kbps for option. Synchronous and asynchronous modes are both available. 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.
Can receive signal instruction from network console of IDNX series node or NTU558(MAS) produced by American company-NET, which enable end-to-end remote allocation, channel monitoring and network console.
