Oh thanks for the answer. I was hoping maybe it was something new. I have always wondered why the basic design (with improvements) have stayed the same so long. Imagine coaxial with ThermaVolt dielectric insulation, graphite nano-wrap shielding and a ICP core. Were talking cable so thin you could lay it on the wall and paint over it and not even notice. Ahh yes, but it all boils down to cost and compatibility. That's why RJ11 hasn't changed in what..60 years?
