EXHIBIT B <br />NORTH METRO I -NET AND DFOI PERFORMANCE STANDARDS <br />Upon completion of the Institutional Network upgrade and the DFOI specified in Section 7 of <br />this Franchise, the Institutional Network and the DFOI shall at all times meet or exceed the <br />following performance standards: <br />I. HFC -Based Institutional Communications <br />A. Transmissions on the I -Net shall comply with the following performance <br />standards (combined upstream and downstream performance): <br />1. Carrier to noise ratio = 45 dB or better. <br />2. Carrier to composite triple beat = minus 53 dB or better. <br />3. Carrier to composite second order = minus 55 dB or better. <br />4. Carrier to cross modulation = minus 55 dB or better. <br />5. Hum modulation = <3%. <br />6. System signal variations (peak to valley) = N/10+2 or better for all coaxial <br />cable portions of the I -Net (where N = the number of amplifiers in <br />cascade). <br />7. In -Channel Frequency Response (Downstream or Upstream) — Under <br />worst-case conditions, the in -channel frequency response for either <br />upstream or downstream channels shall be less than or equal to 3 dB (±1.5 <br />dB). <br />8. Signal Levels (Downstream) — Minimum signal level received at the <br />demarcation point of any HFC I -Net Site will always meet or exceed 10 <br />dBmV. Notwithstanding this requirement, the Grantee shall always work <br />with the I -Net User to ensure successful reception of video, voice and data <br />communications at each I -Net site. <br />9. Signal Levels (Upstream) — The Grantee shall always work with I -Net <br />Users to ensure that the input signal level received upstream on any of the <br />I -Net channels at the amplifiers, Nodes and hubs serving the North Metro <br />Franchise Area will facilitate successful transmission of video, voice and <br />data communications on the I -Net. In relation to this requirement, the <br />Grantee shall ensure that its system inputs are compatible with the output <br />capabilities of typical video, voice and data -over -cable equipment <br />designed for use on hybrid fiber -coaxial networks. <br />B. Testing shall occur as follows, at least twice annually (once during the typical <br />coldest month in the North Metro Franchise Area, and once during the typical <br />hottest month within the North Metro Franchise Area): <br />B-1 <br />
