DSU128 2-wire baseband modem is a sync/async modem that operates in full-duplex mode over 2-wire twisted pair lines. Compatible with RAD ASM-31,LOOP-U3500,TAINET DT128.
DSU128 2-wire multi-rate short range modem is a sync/async modem that operates in full-duplex mode over 2-wire twisted pair lines.At selectable data rates from 0.6Kbps to 128Kbps(or38.4Kbps in asynchronous mode).It uses digital DSP to achieve echo cancellation and high performance 2B1Q line coding technique to transmit data in full-duplex up to 5.5Km,independently of the data rate.DSU128 is compatible with RAD ASM-31,LOOP-U3500,TAINET DT128.
