What can cause the SNRM to increase for a short period?
« on: January 12, 2016, 11:39:23 AM »

Hi what could be the possible cause of my SNRM increasing for a short time then coming back down?



Do you think it could be just crosstalk or does this look like an other issue?

Thanks

a disturber is usually another line that's injecting crosstalk into the D side (PCP to distribution pole) cable bundle.

Oh that's unfortunate as the attainable rate jumps to 73mb. It just shows how much of an impact crosstalk can have on a line.
