You will find this information in TIA/EIA 570-A and the TDMM. I never mentioned any "code" so i'm not sure where that came from. The "recommended" cable type for residential is Cat5e. That is a standard and not a code. We in "Arkansas" do not use Cat3 anymore. The minimum cable rating we use is Cat5e. That is for voice and data. I love a good debate and most of the guys on here preach about holding everyone to a higher standard so i'd like to hear the arguments for Cat3 over Cat5e.
