National Standards. Communications wiring standards are defined by a number of national and international agencies, including the Electrical Industries Association (EIA), the Telecommunications Industry Association (TIA), the Institute of Electrical and Electronics Engineers (IEEE) and the National Electrical Manufacturer's Association (NEMA).
1 100 ohms: This impedance is the standardized impedance to be used in the twisted pair wiring used in structured wiring systems standardized EIA/TIA 568 standard. 2  Both unshielded and shielded CAT5 and better cables used on this kind of applications have 100 ohms impedance (usually at +-15% or better accuracy).n twisted pair wiring testing you can sometimes see terms Basic Link and Channel. The Basic Link configuration is intended for use by cable installers and contractors, testing the fixed wiring in a building.
