11 Page 11 of SUMMARIZED TEST RESULTS The electrical transmission performance testing has been carried out on samples of screened Category 5 (Cat. 5e) RJ 45 Patch Panel from Telebox, type LP248SX. Measurements have been made to 125 MHz. Requirements from MHz are not specified and are presented for information only. Summarized test results are presented in the following clauses, while recordings of electrical performance versus frequency are found in the appendix. The tables in the present section generally inform about the headroom to a specified worst case limiting function which is specified under the table concerned. The various recordings of electrical performance versus frequency in the appendix contains, in red colour, this limiting function specified for the parameter in question. The transmission measurements have been carried out using the test configurations specified in the ISO/IEC, CENELEC and TIA/EIA standards. This means that the following three conditions are covered by the testing: 1. All noise parameters are measured from both the RJ 45 and connecting block sides. For reasons of simplification only the worst case recordings of these two measurements are presented in the appendix. The summarised results of all bi-directional measurements are presented in the tables of the relevant sub-clause. 2. The measurements of near and far end crosstalk have been carried out using both "common and differential mode" (Y-term.) and "differential mode only" (diff-term.) terminations. For reasons of simplification only the worst case recordings of these two measurements are presented in the appendix. The summarised results of all Y-term. and diff.-term. measurements are presented in the tables of the relevant sub-clause. 3. The measurements of near and far end crosstalk have been carried out using both the specified low and high limit de-embedded NEXT plugs whenever this is required by the specifications. Both of these two recordings are presented in the appendix for each of the three combinations of pairs for which high limit plug measurements are specified. Each recording includes, for a specific plug and pair combination, the worst case result of the four combinations of the two termination types and two sides of the connecting hardware. The summarised results of all low and high limit plug measurements are presented in the tables of the present clause. The low limit plug is in the present report understood to be the plug having the lowest numerical de-embedded NEXT value, i.e. the worst NEXT performance, while the high limit plug is understood to be the plug having the highest numerical de-embedded NEXT value, i.e. the best NEXT performance. Both phase angle and absolute value of the applied plugs are in compliance with the requirements of all CENELEC, ISO/IEC and TIA/EIA standards. However, only the measured low and high absolute de-embedded NEXT values are presented in table De-Embedded NEXT Values of Applied RJ 45 Plugs Summarized results of testing of the applied low and high limit plugs are found in table 6.1, and include all six pair combinations measured for absolute value at 100 MHz, as this is the spot frequency for which de-embedded NEXT performance is traditionally reported. Both absolute value and phase angle have been measured from 1 MHz to 100 MHz and comply with the

12 Page 12 of 39 specified limits in the full frequency range for all six pair combinations of applied plugs. However, for simplification these test data are neither presented in table 6.1 nor as recordings in the appendix. Table 6.1 Summarized Results of De-Embedded NEXT Measurements of Absolute Value for Applied RJ 45 Plugs at 100 MHz COMBINATION OF PAIRS DE-EMBEDDED NEXT AT 100 MHz (db) Absolute Value for Low Limit Plugs Absolute Value for High Limit Plugs Specified Covered Range 1/2-3/6 1/2-4/5 1/2-7/8 3/6-4/5 3/6-7/8 4/5-7/8 41,7 49,9 59,2 34,3 41,3 49,9 50, ,6 50, Min. 50 Min ,4-37, Min. 50 It is concluded from table 6.1 and testing performed at 3P that the performance of the applied test plugs complies with the specified Category 5 (Cat. 5e) requirements in the complete frequency range from 1 MHz to 100 MHz. 6.2 Return Loss Summarized results of the testing are found in table 6.2, and include all four tested pairs measured from both sides of the connecting hardware.

Presently this includes only Telebox Patch Panel, type LP248SX. The company Telebox Industries Corporation 4F, No. 306, Sec 1, Ta-Tung Road Hsi-Chin Chen Taipei Taiwan, R.O.C. is qualified at their Hsi-Chih site to produce the connecting hardware in question with a 3P rating as Screened Category 5 (Cat. 5e) ISO/IEC, EN & TIA/EIA Connecting Hardware. The qualification will be valid until failure to pass one of the maintenance test programmes, which will be performed at 12 months intervals. It should be noted that the present testing does not include the reliability test programmes specified in CENELEC, ISO/IEC, IEC and TIA/EIA standards. Only the transmission performance is covered by the 3P qualification and listing of connecting hardware. It is assumed that the contact reliability of the applied RJ 45 jacks is adequate to secure safe interconnection to the patch cords throughout a lifetime of normal application of the connecting hardware.
