      Re: Low Noise Margin

      Sure is possible if there is excessive noise on the line you will be getting large amounts of CRC errors which mean packets need to be resent hence lowering effective throughput.

      Whats the setup like there are you already in the test socket? or using a prefiltered faceplate, is the line audibly clear?

      Noise margin very low so we need to ether find the cause or going to need the line cappping to paper over the cracks.

      Re: Low Noise Margin

      When you reboot router it should resync around the target 7db margin, when you do that does it soon starting dropping to the 4db?, also again is the line nice and clear press 1 to silence the dial tone for a few seconds or call 17070 and do the quiet line test.
