                    1)     Category 6 Cable:

                           a)    All Category 6 distribution cables will be tested in accordance with
                                 procedures outlined in ANSI/EIA/TIA-568-C for the Permanent Link.
                                 Written test results for each cable shall include all four of the primary
                                 field test parameter results. Any cable that fails testing shall be
                                 reported along with the procedures used to rectify the failure (i.e.,
                                 replaced cable, re-terminated jack, etc.). Contractor tests shall utilize
                                 a Category 6 Level III compliant cable tester as described in
                                 ANSI/TIA/EIA-568-C. Electronic results for each UTP Category 6,
                                 4-pair cable will be submitted as part of the Contractor's "As-Built"
                                 project performance acceptance records. In addition to the above
                                 information, the documentation will also include a pass/fail indication
                                 for the specified cable, the test date, the serial number and software
                                 version of the scanner, and a copy of the calibration certificate for the
                                 scanner. Necessary applications for reading the results will be
                                 provided by the requirements refer to ANSI/TIA/EIA-568-C.

                    2)     Category 5E Cable:

                           a)    All Category 5E distribution cables will be tested in accordance with
                                 procedures laid out in TIA/EIA-568-C for the basic link. Written test
                                 results for each cable shall include all four of the primary field test
                                 parameter results. Any cable that fails testing shall be reported along
                                 with the procedures used to rectify the failure (i.e., replaced cable,
                                 replaced jack, etc.). Contractor tests shall utilize a Category 5E Level
                                 II compliant cable tester. Electronic results for each UTP Category
                                 5E four-pair cable will be submitted as part of the Contractor's "As-
                                 Built" project performance acceptance records. In addition to the
                                 above information, the documentation will also include a pass/fail
                                 indication for the specified cable, the test date, the serial number and
                                 software version of the scanner, and a copy of the calibration
                                 certificate for the scanner. Necessary applications for reading the
                                 results will be provided by the requirements refer to ANSI/TIA/EIA-
                                 569-B.

  D.   Document data for each measurement. Data for submittals shall be printed in a summary report
       that is formatted for a ‘Class 3’ administration system as outlined in the BICSI TDMM, Ch. 10
       “Telecommunication Administration”. Data may be transferred from the instrument to the
       computer, saved as text files, and printed and submitted.

  E.   End-to-end cabling will be considered defective if it does not pass tests and inspections.

  F.   Prepare test and inspection reports.
