Operational standards.
Riverside Municipal Code § 5.56.350
in effect5.56.350 - Operational standards.
The CATV system shall be installed and maintained in accordance with the highest and best accepted standards of the industry to the effect that subscribers shall receive the highest possible service. In determining the satisfactory extent of such standards the following among others shall be considered:
A. That the system provide a minimum of 20 channels, capable of delivering to subscribers the entire VHF and FM spectrum and selected portions of the UHF spectrum;
B. That the system, as installed, be capable of passing standard color TV signals without the introduction of material degradation on color fidelity and intelligence;
C. That the system and all equipment be designed and rated for 24-hour per day continuous operation;
D. That the system provides a nominal signal level of 2,000 microvolts across 75 ohms at the input terminals of each TV receiver. A minimum signal of 1,000 microvolts across 75 ohms shall be maintained for at least 95 percent of the operating time;
E. The system signal-to-noise ratio shall not be less than 43 db. (decibels). Signal-to-noise is a figure of merit, thus insuring distribution of picture without noticeable degradation;
F. Hum modulation of a 100 percent modulated picture signal shall not exceed two percent;
G. The system shall not exceed a VSWR (Voltage Standing Wave Ratio) of 1.2 at any point in the system;
H. The sound carrier level on each television channel distributed shall not be less than 17 db. below the level of either adjacent picture carrier;
I. The carrier level of each FM channel distributed shall be not less than 17 db. below the picture carrier level in television channels adjacent to the FM band;
J. Co-channel interference, adjacent channel interference and other extraneous signals, including hum, measured at the receiver input, shall be at least minus 40 db. with respect to the peak carrier level of each desired channel;
K. Isolation between any two subscribers shall be at least 35 db;
L. Radiation from coaxial cables and electronic equipment in the distribution system including power supplies and associated power lines shall be less than ten microvolts per meter at any point at a distance of ten feet. Each power supply or its associated housing shall be equipped with a suitable RF power line filter which shall provide not less than 36 db. of attenuation to all frequency transmitted over this system;
M. Interference from sources external to the system shall not be noticeable with a blank-screen test;
N. All equipment must conform with any pertinent City and/or underwriter's laboratory standards whichever shall be more stringent;
O. The system shall maintain all of the above specifications between ambient temperature limits from minus 20 degrees Fahrenheit to plus 120 degrees Fahrenheit, where "ambient temperature" is defined as the officially recorded City air temperature, and also for AC power line variations between 105 and 130 volts, and between 55 and 65 Hz. The maximum level change at the input to any randomly selected receiver shall be three db. with a temperature change of 50 degrees Fahrenheit, with no adjustment and with the AC line voltage constant within five percent of nominal. The maximum level change shall be three db. for a constant ambient temperature with a voltage variation from 105 to 130 volts.
P. The signal received by the customer shall be substantially the same quality as originally transmitted by the station being received taking into consideration the technical conditions over which the system operator has no control.
