�~Optional data rate: Synchronism 600bps to 128Kbps
�~Asynchronism 600bps to 38.4Kbps
�~It has two kinds of interface at the same time: V.35 and RS232 only need switch to choose
�~Compatible RAD ASM31, TAINET, DT128, LOOP-U3500
�~To setup all of parameters with the switches on the back panel without open machine
�~With good transmitting specialty the longest transmitting di stance in 0.4mm lines can be 5km.
�~Using of high-powered 2B1Q lines coding technology ensures good quality and satisfies low cost.
�~According with V.54 diagnosis agreement and sustaining all kinds of methods to test loopback
�~Without professional working, finishing all kinds of loopback test and wrong code test only by the switches on the front panel
�~With protective lines to over-press lines to avoid lightning strike destroying
�~With two kinds of machine model: standalone and rack mountabl
