1. Introduction of DSL-2M
DSL-2M is a G.SHDSL MODEM, which is developed by FPGA technic. It follows ITU G.SHDSL standard and uses PAM16 encode technic. It can support user data transmite speed at 2.3Mbps.The transmite distance range can be 3.5Km(At 2048kbps)-7.1Km(At 192Kbps) at 26AWG(0.4mm) commucation lines.It can be used for transmiting Voice,Image,user data and so on.The user interface can be V.35 ,Ethernet or G.703.
DSL-2M has strong fuction for monitoring all kinds of troubles.On its panel,there are 9 LEDS,which can display the modem’s running state or fault state.It also has 4 loopback-test buttons on its panel,which can easily judge where the troubles are by making all kinds of loopback test.
