DSU560 Modem

V-DSU560 is a high-performance 2-wire full duplex base-band modem based on DSP and LSI technology. DSU560 is applied on DDN or FR line. It has high quality transmission (transmission distance can reach 5.5Km on 0.5mm line) due to the three reasons: adapts digital DSP to achieve echo cancellation, adaptive equal technology and high-performance 2B1Q 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.

Feature:

Be compatible with NTU560 (MAS) of DATACRAFT

Can receive signal instruction from network console of IDNX series node or NTU560 (MAS) produced by American company-NET, thus enable end-to-end remote allocation, channel monitoring and network console.

Two kinds of data rates: 64Kbps and 128Kbps for option

Synchronous and asynchronous modes are both available.

Two kinds of interfaces: V.35 or V.24 (RS232) for option by a shift switch. Adapt high-performance of 2B1Q line coding technology to ensure high quality and low cost.         

The maximum transmission distance is 5.5Km on 0.5mm line.

Many indicators on front panel to display working status alarm signal, it supports analog loopback test.

Can prevent equipment from over pressure and thunder attack .Internal power supply: DC -48V or AC 220V for option
