A revolution in plant maintenance

March 26, 2014 5:55 pm | by Brian Santo | Articles | Comments

DOCSIS 3.1 turns every single cable modem into a network probe that can be used to identify network impairments. The approach makes use of DOCSIS pre-equalization on the upstream. Different network impairments will have specific signatures that can be sifted out of the pre-equalization data. The technique not only identifies upstream problems, but it also locates them with gratifying precision.
