".:\ ,>",-,,',: :".,'!" EXHIBIT D . . NORTH SUBURBAN I-NET PERFORi'1:ANCE STANDARDS Upon completion of the I-Net upgrade: I. Video Transmission A. Video transmission will comply with the following performance: standards: t. Carrier to noise ratio = 45dB or better 2. Carrier to composite triple beat = 53 dB or better 3. Carrier to composite second order = 55 dB or better 4. Carrier to cross modulation = 55 dB or better 5. System signal level variations (peak to valley) = n + 10 + 2 or better for all coaxial cable portions of the I-Net (where N = the number of amplifiers in cascade). B. Testing will occur twice yearly following the timing established in CFR 76.601 and 76.605. t. From the institution to the longest subscriber cascade. 2. From the institution through the applicable headendlhub site returning back to the same institution. 3. Performed using existing I-Net carriers active it the time of the testing, which will subject them to service interuptions. 4. Completed at Company-designated entry demarcation point at the . institution. 5. The system will meet calculated worst case fully loaded video and audio measurements, taking into consideration existing I-Net data loading at the time tbe measurement is taken. 6. Under ordinary operating conditions. 2. Digital Transmission A. For I-Net that is 50% or more coaxial cable, a Bit Error fulte of 1 X 10(-8) at the demarcation point. t. Outage times not included 2. Ordinary operating conditions B. For I-Net that is 50% or more fiber optic cable, a Bit Error Rate of 1 X 10(- 9) at the demarcation point. t. Outage times not included 2. Ordinary operating conditions C. For both coaxial and fiber network, the company will meet or exceed a reliability factor of 99.965% on an annual basis. D. Testing will occur twice yearly, during tbe months of JanuarylFebruary and July/August. e
