Hi,


we have problems with a few G.SHDSL lines and I wanted to ask, if there is a possibility to raise the tolerance for errors on a G.SHDSL line? I found the command "snr margin" and I don't really understand the description for this command. Could you please explain what the commands "snr margin current" and "snr margin snext" do on a Cisco 878 (Cisco 1803). Can it help to make a line more stable? If yes, then how it works and which values should be used.

The operating range of HDSL is limited to 12,000 feet. The SNR margin values can be set as follows

shdsl margin min 0

shdsl margin target 3

shdsl margin threshold 0
