  29. New Standard • On June 20, 2002, the Category 6 (or Cat 6) addition to the TIA-568 standard was published. • This new standard specifies the original set of performance parameters that need to be tested for Ethernet cabling as well as the passing scores for each of these tests. • A quality cable tester is the Fluke DSP-LIA013 Channel/Traffic Adapter for Cat5e.
