Broadband snr margin
WebJun 20, 2014 · While many broadband lines can function perfectly adequately with a 3 dB target SNR margin without issue, DLM systems often set the target SNR margin above this figure. For example, the default target SNR margins used by BT and TalkTalk equipment are 6 dB and 9 dB, respectively. WebThe standard signal attenuation spread for a given speed is somewhere in the region of 15-20dB for ADSL2/2+ speeds and 25-30dB for ADSL1 speeds. The following is a …
