<br />13 WARRANTY <br /> <br />Either a basic link or channel model configuration may be applied to the horizontal and/or backbone <br />sub-systems of the structured cabling system. Applications assurance is only applied to a channel <br />model configuration. All channels are to be qualified for linear transmission performance up to 300 <br />MHz to ensure that high-frequency voltage phase and magnitude contributions do not prove <br />cumulative or adversely affect channel performance. <br /> <br />13.1 SYSTEM WARRANTY <br /> <br />A twenty (25) year warranty available for pending category 6 structured cabling system shall be <br />provided for an end-to-end channel model installation which covers applications assurance, cable, <br />connecting hardware and the labor cost for the repair or replacement thereof. <br /> <br />Additional features of the warranty shall include: <br />· Margin over proposed category 6 channel specifications on all parameters across the entire <br />frequency range of 1-300MHz as noted below: <br /> <br /> Guaranteed <br />Parameter Margin <br /> 1-300 MHz (dB) <br />Insertion Loss 0.1 dB <br />NEXT Loss 2.9 dB <br />PS NEXT Loss 3.5 dB <br />ACR 3.1 dB <br />PS ACR 3.6 dB <br />ELFEXT 3.0 dB <br />PS ELFEXT 3,0 dB <br />Return Loss 0.6 dB <br />Propagation Delay 20 ns <br />Delay Skew 10 ns <br /> <br />· Performance claims based on worst case testing and channel configurations <br />· Applications will not exceed bit error rates specified by IEEE, A TM Forum, ANSI and ISO <br />standards for all current and future applications operating on compliant LAN equipment that <br />has been designed for use with a compatible category or class of balanced twisted-pair <br />cabling. <br /> <br />13.2 PRODUCT WARRANTY <br /> <br />The manufacturer of passive telecommunications equipment used in a manner not associated with <br />the Systems Warranty must have a minimum five (5) year Component Warranty on all its product. <br />The Products Warranty covers the components against defects in material or workmanship under <br />normal and proper use. <br /> <br />13.3 APPLICATIONS SUPPORTED <br /> <br />Existing and future applications supported for a channel model warranty include those approved by <br />the Institute of Electronic and Electrical Engineers (IEEE), the Asynchronous Transfer Mode (A TM) <br />Forum, the American National Standards Institute (ANSI) or the International Organization of <br />Standards (ISO) that specify compatibility with the cable referenced herein, <br /> <br />s\~ <br />
