SETTING UP MODEMS FOR STREAMYX 1 DSL Technologies 1.1 ADSL Asymmetric Digital Subscriber Line ITU G.992.1 - G.DMT - 8.0Mbit/s, 1.0Mbit/s ITU G.992.2 - G.Lite - 1.5Mbit/s, 0.5Mbit/s ITU G.992.3/4 - ADSL2 - 12Mbit/s, 1.0Mbit/s ITU G.992.5 - ADSL2+ - 24Mbit/s, 1.0Mbit/s 1.2 SDSL Symmetric Digital Subscriber Line 1.3 SHDSL Symmetric high-speed digital subscriber line ITU G.991 1.4 VDSL Very high bit-rate Digital Subscriber Line ITU G.993.1 - VDSL ITU-T G.993.2 - VDSL2 2 Signal Level Guide 2.1 ADSL Downstream SNR = 15 dB. Higher is better, minimum = 6 dB. Downstream Power = < 15 dBm. Lower is better. Upstream SNR = 10 dB. Higher is better. Upstream Power = < 15 dBm. Lower is better. Downstream Attenuation = < 30 dB Lower is better, maximum = 60 dB. Upstream Attenuation = < 30 dB Lower is better, maximum = 60 dB. 2.2 ADSL2+ Downstream SNR = 06 dB. Higher is not better, within range is better = 05 - 07 dB. Downstream Power = < xx dBm. Lower is better. Upstream SNR = 06 dB. Hig
