EXECiJTIVE SUMIVIARY Columbia Telecommunications Corporation ("CTC") conducted an inspection of the cable system in the franchise area served by Comcast Communications in the City of Spokane Valley, Washington from April 19 - 20, 2006. This review included an inspection of the headend, electrical testing of the system, and inspection of portions of the physical plant. The purpose of our assignment was to determine if the cable system as operated by Comcast Communications meets the terms of the technical requirements of the Cable Television Franchise Agreement and to determine if the network is performing at or above the performance levels defined by the Federal Communications Commission. 1.1 Adequacv of tbe Overal9 Picture Oualitv Our examination and quantitative measurement of the picture quality of the individual cable channels at the headend and at four tests points located in selected neighborhoods of the City verified that the cable system provides excellent picture quality on all television broadcast, analog satellite and satellite delivered digital video services. We found that the public, educational, and government channels carried on the basic tier were delivered to subscribers with quality that was comparable to the commercial broadcast services. All of the individual channels measured by CTC during the onsite visit as well as the measurement data contained in the FCC proof test data provided by Comcast confirm that the system exceeds the FCC minimum performance criteria for cable systems. Further, we found that the cable network and transmission system transports signals to the subscriber with a level of signal quality that is highly comparable with the quality to the signals observed at the headend. 1.2 Cable Netvvork Phvsical Plamt In addition to the system testing, CTC inspected the physical cable plant occupying public and private rights-of-ways. With regard to the transmission plant inspected on the utility poles and underground cable plant, we found the cable plant to be in generally good-to-very good condition in relationship to other cable systems that we have inspected, and more specifically, with relationship to the other utilities serving the City. There were no obvious problems identified, such as hanging cables, missing cable guy guards, or ungrounded cable plant. We observed that pole-mounted power supplies were locked and properly grounded as required. W ith regard to subscriber drop cables that connect subscriber residences to the cable system, we found a significant number of cable drops that were not compliant with the current electrical code. More detailed information regarding the non-compliant drop cables is provided in Section 5.2. 1.3 Public. Educational, and Government Transrnflssion Facilities As part of our testing, we examined the quality of the public, educational, and government ("PEG") channels. PEG channels carry locally produced programming for subscribers in Spokane Valley and other communities served by the cable system. PEG programming covers a wide range 1 Spokane Valley- 2006 Draft of video and imaging material produced locally by governments and educational organizations such as the Cities of Spokane Valley, Spokane, local colleges, as well as locally produced independent programming. At present, there is no separate PEG channel assigned to the City of Spokane Valley. The program feeds for the existing PEG programming consists of dedicated fiber optic links connecting the program origination centers to the Spokane headend. 2 Spokane Valley- 2006 Draft II. SYSTEM DESCIZIPTION AND OPERATION The cable television system in Spokane Valley is part of the Comcast greater Spokane metropolitan area system. The Spokane Valley systems are served from the Comcast headend located at 1717 East Buckeye Avenue in Spokane. This site includes all headend equipment to receive, process, and monitor signals for transmission to subscribers. The Spokane Valley system was upgraded from a bandwidth of 450 MHz to 750 MHz technology during the 2000-2002 time period. The upgraded system offers a wide range of analog and digital television channels, pay-per-view channels, video on demand, high-definition television, and high- speed data services. The bandwidth in MHz is a measure of the systems capacity to provide services to subscribers. The very newest cable TV systems have a capacity of up to 860 MHz. The Comcast system has a capacity of 750 MHz about 110 MHz less the most modern state of the art systems. In the major television markets that have 20 or more local TV broadcast channels; this extra capacity is often needed to support the traditional cable programming as well as the many newer interactive services. In view of the modest number of local broadcast stations in the Spokane area as well as the upcoming move by the FCC to all digital broadcast stations by the year 2009, we find the 750 MHz system, which employs modern digital compression transmission technology, adequate to meet the existing and projected near-term future network capacity needs for the subscribers in Spokane Valley. 2.1 Headend On April 19, 2006, CTC inspected the headend site. The headend facility serves as the network control for the cable system. In addition to serving the City of Spokane Valley, the headend also serves Comcast cable customers in Spokane and other nearby areas. A system overview diagram for the network is provided in Figure 1. 3 Spokane Valley- 2006 Draft Figure 1: Spokane Cable System Configuration Spokane Television Spokane Broadcast Headeed ~ - Rirect Flber FBBdf Spokane Valley PEG Proqram Feeds , • ~ ~ VOO Servers ~ j • • j ~ Analog and Digital • ~ j Satellite Public ; Programming Cintemet • ~ • Spokane Optical o !

A stand-alone back-up diesel generator has been installed in the headend building that automatically goes into operation in the event of failure of the commercial power. The 750 kW generator has more than sufficient power to operate the headend equipment continuously until commercial power is restored (see Figure 5). The UPS maintains continuous operation of the network during the transmission phase between commercial power operation and the back-up generator.

This is an acceptable cascade length in a recently rebuilt system. The architecture is a standard design for cable systems upgraded in the past few years (see Figure 1 in Section 2.1). The average number of residential dwelling units passed per fiber optic node is 1,000 or less, with a maximum number passed of 2,000 units. The electronic equipment in the fiber node is capable of segmenting the return path into multiple paths so that the maximum number of residences passed on a return can be reduced to 500 dwelling units. This network segmentation effectively multiplies the return bandwidth available to interactive services, such as cable modems, by a factor of four. It allows for an immediate upgrade of the system by simply inserting modules into existing equipment to expand the network capacity. Approximately one-third of the nodes in Spokane Valley are connected to optical hubs which expand the capacity of existing fiber by creating additional optical wavelength in existing fiber links connected to the headend. Comcast uses this relatively new technology to serve Spokane Valley and other adjacent communities. The upper system bandwidth is 750 MHz providing 700MHz downstream transmission capacity. The upgraded network has unassigned bandwidth that can support additional services in the future. Comcast engineers estimate that there are 186.8 underground miles and 358.64 aerial miles of cable plant, for a total of 545.44 miles. The power supplies for the cable plant are backed-up with 3 or 6 batteries that are capable of operating the system in the absence of external primary power for 3 to 4 hours. The power supplies have a remote sta.tus monitoring system that allows the system managers to remotely monitor the battery charge level and to alert the operators when power supplies are operating in the stand-by mode. Based on the findings of our inspection, we conclude that the existing cable network has sufficient capacity to support advanced interactive cable services, such as video on demand, telephony and high speed Internet (cable modems). 2.3 Subscriber Channels The Spokane Valley system provides 75 analog channels, 54 digital audio channels, and more than 170 digital channels. The Comcast channel line-up is provided in Figure 6. The Limited tier consists of 32 analog channels, which are a mix of local off-air broadcast channels, imported broadcast channels, and PEG services. All system subscribers receive the Limited Tier. The Basic Tier consists of an additional 43 analog channels that mainly provides satellite delivered programming. Digital channels are received from the satellites and re-packaged or groomed onto the various digita.l channels carried on the system. Standard definition digital service (SDTV) subscribers use either the Motorola Model DCT 2000 converter box for standard (NTSC) format digital service or the DC 6200 converter box for the HDTV service. 7 Spokane Valley- 2006 Draft At the time of our inspection, Comcast reported the following subscriber base in the City of Spokane Valley: Total dwelling units passed 45,644 Video service subscribers 23,179 Digital tier subscribers 8,833 8 Spokane Valley- 2006 Draft Figure 6: Analog Channel Line-tTp Channel ~ Channel 2-KREM (CBS) 139-ABC Family 3-KAYU (FOX) ~ 40-Nickelodeon ~ 14-XLY (ABC) ~ 41-I)isne_y Channel ~ I 5-City Cable 5-TVW ~ 42-Cartoon Network 16- KHQ (NBC) ~ 43-Animal Planet ' 7- KSPS ( PBS) 144-CNN ~ 8-PAX-TV I 45-Headline 1Vews ~ 9-Discovery Channel 146-CNBC 10-Home Shopping Network 147-1VISNBC 11-ESPN ~ 48-FOX 1Vews Channel ~ 12-ACE-TV ~ 49-Court TV ~ 13-QVC ~ 50-Oarygen ~ 14-Community ProductionlNASA ~ 51-Lifetime 15-Educational Access 152-A&E ~ ~ 16- Educational Access ~ 53-FX ~ ~ 17- Educational Access ~ 54-'TNT ~ 18- Educational Access ~ 55-TBS ~ ~ 19- Educational Access 156-BE'T ~ 20-The Weather Channel ~ 57-SQike TV 21-WGN ~ 58-gJSA 122-KSKN (WB) ~ 59-Sci-Fi Cbannel I 23-Norhtwest Cable News ~ 60-Comed_y Central 124-KQUP . ~ 61-Country Music Television 25-TVW 162-VH1 26-KCDT 163-NI'I'V ~ 27-C-SPAN I 64-E!

VOD services have been offered to subscribers on this system for more than six months. 2.5 Emergencv Alert Svstem The nationwide Emergency Alert System ("EAS") enables authorized government authorities to override the programming on a cable system to provide emergency information to subscribers. The minimum requirements for EAS system operation are outlined in the FCC rules and regulations. These regulations detail a testing procedure and the documentation required. The Spokane Valley Comcast system uses the Sage system (see Figure 7). According to Comcast, a full-screen message is displayed on all analog and digital channels, except for local off-air channels, which requested that the cable operator not override its channels. The Sage system provides an EAS message on all analog channels. The digital subscriber set-top converters are automatically force-tuned to an analog channel to view the EAS message. The EAS equipment is programmed to forward only weather, state primary, state, local, federal, and required test alerts to the subscriber. Figure 7: Emergency Alert System Equipment . ~ , :y e ~4~ '~.,,--.",r"~ ` . , t " ~ --ti _ - 1 .ic•~__4 ~-!~~e ~ ' The cable operator is required to maintain records documenting the FCC-required EAS testing results as well as recent copies of the FCC technical performance tests in a Public Reference file that is available for review by the general public. As part of our inspection, we reviewed the Public file and found that it contained the required technical materials. 10 Spokane Valley- 2006 Draft 2.6 Public. Educational, and Government Channels The Comcast headend receives programming provided by the PEG programmers on dedicated fiber optic transmission links. The PEG programming in Spokane Valley comes from providers in the City of Spokane. The following PEG programming is carried on the system: • Channel 5: Spokane City Channel 0 Channel 14: Community Production • Channel 15: Educational Access a Channel 16: Educational Access • Channel 17: Educational Access • Channel 19: Educational Access The City of Spokane Valley currently has no local source of PEG programming. There do not appear to be any technical barriers to providing specific PEG channels for Spokane Valley. This capability might be implemented by adding a channel to the current line or by segmenting the system and replacing one or more of the Spokane City channels with a Spokane Valley channel. If live origination or local program playback is desired, then a program feed line from Spokane Valley to the Comcast headend will have to be implemented. 2.7 Cable Modem Service Comcast provides high speed Internet through cable modem service. The routing and control network equipment is manufactured by Cisco and is located at the headend. The subscribers of cable modem service access the Internet through a network hub controller located at the headend (see Figure 1). Comcast did not provide any data on the number of customers subscribing to the cable modem service. 11 Spokane Valley- 2006 Draft III. PERIFOIZMANCE T'ESTIlNG The FCC requires semi-annual Proof-of-Performance ("proofl') tests to verify the system meets the FCC's minimum technical standards. The tests must be performed once in the winter and once in the summer. The testing procedures presume that a sample of ineasurements taken for a number of channels at a number of locations across the system will be representative of the system as a whole. However, the operator is required to have all channels meet the FCC minimum technical requirements. The number of channels and locations to be tested is determined using an FCC formula based on the number of subscribers and the cable system design. Prior to the onsite test and inspection, we reviewed the results of the three most recent sets of proof tests conducted by Comcast: Winter 2005, Summer 2005, and Winter 2006. The test data and supporting documenting were provided in an extremely detailed and comprehensive form. The FCC requires the tests to be performed to ensure that all subscribers receive a basic minimum level of service. The Spokane Valley system performs at a level substantially above the FCC minimum standards. The FCC standards, if achieved, deliver a picture to the subscriber similar in quality to a good consumer grade VHS video tape. The industry goal is to provide a picture of higher quality, more in line with DVD quality. Signal amplitude level tests and subject monitoring tests were performed and recorded for all analog channels. Further, the FCC requires cable operators to perform a more detailed signal quality testing on a select number of analog video channels to provide a quantitative measurement of the system performance. For the 750 MHz system, Comcast is required to examine 9 channels in detail. For the 9 channels selected, measurements were made of the signal-to-noise ratio, and second and third order distortions or other coherent disturbances. A hum measurement is required on at least one channel. Frequency measurements of both carrier and separation are also required. The FCC requires that each cable operator measure and record signal leakage radiating into the air from a cable plant to demonstrate compliance with a cumulative leakage index ("CLI"). Signal leakage is caused by defects in the distribution hardware, which can cause interference with other communications signals such as aeronautical and navigation signals. To protect against these harmful signals, the FCC requires that the cable operator check the CLI of the cable plant at least once a year. The CLI tests verify the isolation of the cable system from the outside world. An ideal cable system neither radiates radio frequency signals nor allows external signals to enter or leak into the cable system. As a part of our testing, CTC used the Comcast leakage test equipment at each of the test locations to monitor for the level of signals radiated from the cable system. No measurable leakage was encountered during our tests. The required FCC leakage measurements may be accomplished by either extensive ground-based observations or by measurements made while flying over the system. The most recent flyover test was conducted on August 21, 2005 by Martech Engineering a firm that specializes in performing CLI tests. The Martech certification showed that 99.64 % of the Comcast Spokane system had radiation levels below the allowable FCC lOµV/m field level and therefore is in full compliance. 12 Spokane Valley- 2006 Draft On April 19 and April 20, 2005, in cooperation with Comcast technical staff, CTC performed a subset of the FCC proof tests at the headend and at four locations in the City of Spokane Valley. The headend tests were first made to confirm that the signals assembled at the headed were properly received and processed prior to transmission on the system, and that they were all adjusted to the same audio and video carrier levels. Each of the analog and a few selected digital channels were examined. Starting with the basic tier, we examined each channel for picture quality. For the proof tests we selected 9 channels for testing at the following sites: • Test Point 1: 14220 East Mission, Spokane Valley Node SZE3 a Test Point 2: Robie & l Oth, Spokane Valley Node SZEW • Test Point 3: 10605 East Buckeye St. Spokane Valley Node SDWA • Test Point 4: 8th& Joel, Spokane Valley Node SDSP A Stealth signal level meter model SDA4040D supplied by CTC, and a television receiver and spectrum analyzer provided by Comcast was used to conduct tests of the signal level, carrier-to- noise, hum, and subjective picture viewing tests at the sites. The detailed test results are provided in Appendix A. Overall, the visual testing and quantitative measurements support that the system was operating properly at all test points. Measurements were made with regular programming to minimize subscriber inconvenience. Typically, FCC proof ineasurements are made with the removal of programming and may result in slightly better measurement results. All test points met FCC minimum technical requirements. 13 Spokane Valley- 2006 Draft IV. PHYSICAL PI.ANT Il`15PEC'TION A physical inspection of the cable plant, which included both underground and aerial construction, was conducted in the area around the proof test sites. The inspection concentrated on an examination of the quality of the plant construction, appearance, and compliance with national construction standards. The national inspection standards and authorities, along with descriptions of the violations, are included in this section of the report. Accompanied by Comcast representatives, CTC inspected cable plant in the public rights-of-way and at individual subscriber residence connections ("drops") in residential areas. These walkout inspections were focused in the vicinity of the test points concentrating at the Mission and l Oth Street sites. The areas selected for inspection represented a reasonable cross-section of established, new aerial, and underground areas for plant and drop inspection. The areas were selected by CTC in concurrence with City staff and Comcast representatives. The specific areas examined were in and around the neighborhoods of: • Inspection Area 1: Mission Avenue, Spokane Valley o Bolivar Avenue o Bannen Avenue o Inspection Area 2: Mallon Avenue, Spokane Valley . o Best Road o Evergreen Road • Inspection Area 3: Robie , Spokane Valley 0 10~' Avenue . 0 11 t' Avenue • Inspection Area 4: Perrine Avenue, Spokane Valley 0 12t' Avenue 0 13t' Avenue During the physical plant inspection, we did not find any significant violations on the cable system plant that were under the control of the cable company. 4.1 Phvsical Plant Standards There are two primary national construction standards cited with which the cable system must comply. The first standard, the National Electrical Safetv Code ("NESC") published by the Institute of Electrical and Electronics Engineers, Inc., 2002 and revisions of 2005, is the primary guide to construction of the cable system in the public rights-of-way. The NESC is a national code designed to provide standards and work rules to protect persons against hazards from the installation, maintenance, and operation of electrical systems and communications lines. 14 Spokane Valley- 2006 Draft The second standard is the National Electrical Code ("NEC") published by the National Fire Protection Association, Inc., 2002 and revisions of 2005. This national code establishes rules for the safe installation of electrical conductors and equipment. Other industry standards and authorities for construction and installation practices will also be mentioned as they relate to problems we found that warrant correction. During our inspection of the cable plant in the areas around the test points and the drop inspection, we did not find any infractions on the poles relating to these codes. The following sections address the categories for violations of physical plant construction that we look for in the public rights-of way. 4.1.1 Bonding and Grounding We inspect bonding and grounding according to NEC and NESC and industry standards for the safety of workers on the aerial and underground cables and at subscriber homes and equipment. Grounding protects against injury from lightning and surges of excessive electrical current on the system. Grounding is required for electrified system components at specified locations along the plant itself. This is accomplished by bonding the cable plant and equipment to the common neutral ground of the other utilities on the poles. Alternatively, when there is no other ground, the cable system is directly grounded with a ground rod at the site where grounding is required. Bonding creates "the permanent joining of inetallic parts to form an electrically conductive path that ' ensures electrical continuity and the capacity to conduct safely any current likely to be imposed" (NEC ART. 100). The authorities for reporting these kinds of violations may be found in the following: • NEC, Rules 820-33, 820-40; and • NESC, §092C, §093D, §215, and §239. No grounding or bonding violations were found during our inspection. 4.1.2 Lashing In aerial portions of the cable system, the cables are attached to steel cables or "strand" that is bolted to the poles. A strong thin lashing wire is wrapped around both the cable and strand to secure the cable to its supporting strand. This practice places the weight of the cable on the strand rather than on the cable itself. 15 Spokane Valley- 2006 Draft Improper lashing can result in undue stress on the cable and connectors, potentially causing signal quality problems. If the lashing wire breaks and unravels, it usually causes the cable to fall from its supporting strand toward the ground, thereby reducing clearances over streets, driveways, or sidewalks and presenting hazards to vehicular and pedestrian traffic. No loose or broken lashing wires were observed during the inspection. 4.1.3 Construction The construction category addresses the manner in which the cable system is built. Poor construction practices are evident in such violations as bolts of improper length, which if too long create hazards for personnel climbing the poles, or if too short fail to secure the cables to the poles (NESC §217A4). Other violations in this category include missing bolts, strand that is not attached to poles, strand that does not have the proper tension, cable supports and spacers that are missing or improperly installed, and equipment that is improper for the system. No construction violations were observed in the inspected areas. 4.1.4 Clearances Clearances of the cables from the ground, streets and sidewalks, and other utilities are specified in national codes such as the NESC §23 and NESC Tables 232 and 234. All cables on the utility poles and underground should be placed in a manner to avoid contact with one another. The codes establish acceptable distances between power, telephone, and other communications lines placed on the same poles and in the same area in the public rights-of-way or public utility easements. Proper distance between cable television lines and other utility cables provides a level of safety for all workers on the poles. The clearance dista.nces from power lines and streets and sidewalks are established to permit safe and unhindered access to cables on the poles and to avoid obstructions to vehicular traffic and pedestrians passing under the cables. No violations were observed in the inspected areas. 4.1.5 Guying and anchoring In aerial construction, guy wires are necessary to provide additional support to the utility pole where the weight of cables on the poles is greater than can be safely supported by the poles alone. Guy wires are required not only for poles that support a large number of cables, but also for poles supporting very long spans of cable, and on corners or at the end-of-lines where there is also additional weight on the poles. Missing or improperly installed guy wires can create a public safety hazard because of a greater potential for pole failure under stress from high winds, accidents, or pole degradation over time. The steel cables used to guy the poles must be properly bolted to the poles and anchored in the ground at prescribed tensions. At ground level, the guy wire itself is required to be covered with a 16 Spokane Valley- 2006 Draft . plastic "guard" to alert passersby to the presence of the wire and protect pedestrians from accidental injury. The requirements for guy wire violations are documented in NESC Rules 261 B, 261 C, 261 D, and 264. No violations in this category were observed in the inspected areas. 4.2 Subscriber I)rop-Related Violations "Drops" are the wires that connect the subscriber homes to the cable system on the street. Under the NEC, drops are required to meet specific construction standards for attachment to the homes. These standards have requirements for attachment to the residence, clearance from the ground or depth of buried cable, and grounding to protect against shock, equipment damage, and fire hazards. Drop violations include drops from aerial plant down a utility pole to an underground service connection not being secured to the pole and which may become inadvertently snagged and disconnected. Safety is a significant concern in installation and maintenance of drops. For example, a common operator practice is to place a temporary unburied drop to a home serviced by underground plant. This can also occur when the ground is frozen or snow covered and cable cannot be buried at the time of installation. This may be acceptable for a few days, if properly guarded or marked, but when left exposed for weeks it is not only an annoyance to subscribers but presents a safety hazard in the public rights-of-way. These situations are also reported as violations. Standards for drop installation and maintenance are governed by generally accepted industry practices and by the NEC §250 and §820. Drop Grounding During the drop inspection, we found a substantial portion of the accessible subscriber drops inspected were grounded at the dwelling unit in a manner not provided for in the current electrical code; however, they were sanctioned in codes prevailing at the time of original insta.llation. The drops in question represent older homes where the power, telephone and cable enter the property in different areas of the house. Figure 8 is a photo illustrating a drop grounded to a water pipe which may or may not be grounded to the power network as required under the current code. 17 Spokane Valley- 2006 Draft Figure 8: Cable Grounded to Egterior Water Pipe _ - = - _ ~ . . `k • ~ .

Where public utilities are placed underground, cable and related equipment must also be placed underground. Cables are to be buried at specified depths and at specified dista.nces from public utilities. When repairs or replacement of the cables is necessary, temporary exposed "jumper" cables are often installed to maintain service while work to properly install and bury the new cables is scheduled. When temporary jumper cables are installed, the cables should be marked with tape or cones to alert the public to the hazard and to protect the public from injury. Temporary cables must be replaced with properly installed cables as soon as possible. In other cases, drops may be installed without properly burying the cable in order to facilitate a subscriber service connection, with the cable operator scheduling burial of the cable for a later date. These unburied cables also present safety hazards to residents passing by the cables. When we find this type of installation that has been in place for some time or is unprotected, we report it as a violation. Temporary cables are addressed in the NESC at §230 A(2)(d). No violations were observed in the inspected areas. 4.2.1 Drop Clearance We did not observe any locations where the cable drop had insufficient clearance from power cables.

VIDEO AND CABLE TELEVISION SERVICE Subpart K T'echnical Standards Sec. 76.601 Performaoce tests. (a) The operator of each cable television system shall be responsible for insuring that each such system is designed, installed, and operated in a manner that fully complies with the provisions of this subpart. (b) The operator of each cable television system shall conduct complete performance tests of that otherwise noted below. The performance tests shall be directed at determining the extent to which the system complies with all the technical standards set forth in Sec. 76.605(a) and shall be as follows: (1) For cable television systems with 1000 or more subscribers but with 12,500 or fewer subscribers, proof-of-performance tests conducted pursuant to this section shall include measurements taken at six (6) widely separated points. However, within each cable system, one additional test point shall be added for every additional 12,500 subscribers or fraction thereof (e.g., 7 test points if 12,501 to 25,000 subscribers; 8 test points if 25,001 to 37,500 subscribers, etc.). In addition, for technically integrated portions of cable systems that are not mechanically continuous (i.e., employing microwave connections), at least one test point will be required for each portion of the cable system served by a technically integrated microwave hub. The proof-of-performance test points chosen shall be balanced to represent all geographic areas served by the cable system. At least one- third of the test points shall be representative of subscriber terminals most dista.nt from the system input and from each microwave receiver (if microwave transmissions are employed), in terms of cable length. The measurements may be taken at convenient monitoring points in the cable network: Provided, that data shall be included to relate the measured performance of the system as would be viewed from a nearby subscriber terminal. An identification of the instruments, including the makes, model numbers, and the most recent date of calibration, a description of the procedures utilized, and a statement of the qualifications of the person performing the tests shall also be included. (2) Proof-of-performance tests to determine the extent to which a cable television system complies with the standards set forth in Sec. 76.605(a) (3), (4), and (5) shall be made on each of the NTSC or similar video channels of that system. Unless otherwise as noted, proof-of-performance tests for all other standards in Sec. 76.605(a) shall be made on a minimum of four (4) channels plus one additional channel for every 100 MHz, or fraction thereof, of cable distribution system upper frequency limit (e.g., 5 channels for cable television systems with a cable distribution system upper frequency limit of 101 to 216 MHz; 6 channels for cable television systems with a cable distribution system upper frequency limit of 217-300 MHz; 7 channels for cable television systems with a cable distribution upper frequency limit to 300 to 400 MHz, etc.). The channels selected for testing must be representative of all the channels within the cable television system. (3) The operator of each cable television system shall conduct semi-annual proof-of- performance tests of that system, to determine the extent to which the system complies with the technical standards set forth in Sec. 76.605(a)(4) as follows. The visual signal level on each channel shall be measured and recorded, along with the date and time of the measurement, once every six hours (at intervals of not less than five hours or no more than seven hours after the previous measurement), to include the warmest and the coldest times, during a 24-hour period in January or February and in July or August. (4) The operator of each cable television system shall conduct triennial proof-of-performance tests of its system to determine the extent to which the system complies with the technical standards set forth in Sec. 76.605(a)(11). (c) Successful completion of the performance tests required by paragraph (b) of this section does not relieve the system of the obligation to comply with all pertinent technical standards at all subscriber terminals. Additional tests, repeat tests, or tests involving specified subscriber terminals may be required by the Commission or the local franchiser to secure compliance with the technical standards. (d) The provisions of paragraphs (b) and (c) of this section shall not apply to any cable television system having fewer than 1,000 subscribers: Provided, however, that any cable television system using any frequency spectrum other than that allocated to over-the-air television and FM broadcasting (as described in Sec. Sec. 73.603 and 73.210 of this chapter) is required to conduct all tests, measurements and monitoring of signal leakage that are required by this subpart. A cable television system operator complying with the monitoring, logging and the leakage repair requirements of Sec. 76.614, shall be considered to have met the requirements of this paragraph. However, the leakage log shall be retained for five years rather than the two years prescribed in Sec. 76.1706. Note 1 to Sec. 76.601: Prior to requiring any additional testing pursuant to Sec. 76.601(c), the local franchising authority shall notify the cable operator who will be allowed thirty days to come into compliance with any perceived signal quality problems which need to be corrected. The Commission may request cable operators to test their systems at any time. Note 2 to Sec. 76.601: Section 76.1717 contains recordkeeping requirements for each system operator in order to show compliance with the technical rules of this subpart. Note 3 to Sec. 76.601: Section 76.1704 contains recordkeeping requirements for proof of performance tests. Sec. 76.605 Technical standards. (a) The following requirements apply to the performance of a cable television system as measured at any subscriber terminal with a matched impedance at the termination point or at the output of the modulating or processing equipment (generally the headend) of the cable television system or otherwise as noted. The requirements are applicable to each NTSC or similar video downstream cable television channel in the system: (1) (i) The cable television channels delivered to the subscriber's terminal shall be capable of being received and displayed by TV broadcast receivers used for off-the-air reception of TV broadcast signals, as authorized under part 73 of this chapter; and (ii) Cable television systems shall transmit signals to subscriber premises equipment on frequencies in accordance with the channel allocation plan set forth in CEA-542-13: "Standard: Cable Television Channel Identification Plan," (Incorporated by reference, see Sec. 76.602). . (2) The aural center frequency of the aural carrier must be 4.5 MHz - 5 kHz above the frequency of the visual carrier at the output of the modulating or processing equipment of a cable television system, and at the subscriber terminal. (3) The visual signal level, across a terminating impedance which correctly matches the internal impedance of the cable system as viewed from the subscriber terminal, shall not be less than 1 millivolt across an internal impedance of 75 ohms (0 dBmv). Additionally, as measured at the end of a 30 meter (100 foot) cable drop that is connected to the subscriber tap, it shall not be less than 1.41 millivolts across an internal impedance of 75 . ohms (+3 dBmV). (At other impedance values, the minimum visual signal level, as viewed from the subscriber terminal, shall be the syuare root of 0.0133 (Z) millivolts and, as measured at the end of a 30 meter (100 foot) cable drop that is connected to the subscriber tap, shall be 2 times the square root of 0.00662(Z) millivolts, where Z is the appropriate impedance value.) (4) The visual signal level on each channel, as measured at the end of a 30 meter cable drop that is connected to the subscriber ta.p, shall not vary more than 8 decibels within any six- month interval, which must include four tests performed in six-hour increments during a 24-hour period in July or August and during a 24-hour period in January or February, and shall be maintained within: (i) 3 decibels (dB) of the visual signal level of any visual carrier within a 6 MHz nominal frequency separation; (ii) 10 dB of the visual signal level on any other channel on a cable television system of up to 300 MHz of cable distribution system upper frequency limit, with a 1 dB increase for each additional 100 MHz of cable distribution system upper frequency limit (e.g., 11 dB for a system at 301-400 MHz; 12 dB for a system at 401-500 MHz, etc.); and (iii) A maximum level such that signal degradation due to overload in the subscriber's receiver or terminal does not occur. (5) The rms voltage of the aural signal shall be mainta.ined between 10 and 17 decibels below the associated visual signal level. This requirement must be met both at the subscriber terminal and at the output of the modulating and processing equipment (generally the headend). For subscriber terminals that use equipment which modulate and remodulate the signal the rms voltage of the aural signal shall be maintained between 6.5 and 17 decibels below the associated visual signal level at the subscriber terminal. (6) The amplitude characteristic shall be within a range of 2 decibels from 0.75 MHz to 5.0 MHz above the lower boundary freyuency of the cable television channel, referenced to the average of the highest and lowest amplitudes within these frequency boundaries. The amplitude characteristic shall be measured at the subscriber terminal. (7) The ratio of RF visual signal level to system noise shall not be less than 43 decibels. For class I cable television channels, the requirements of this section are applicable only to: (i) Each signal which is delivered by a cable television system to subscribers within the predicted Grade B contour for that signal; (ii) Each signal which is first picked up within its predicted Grade B contour; (iii) Each signal that is first received by the cable television system by direct video feed from a TV broadcast sta.tion, a low power TV station, or a TV translator station. (8) The ratio of visual signal level to the rms amplitude of any coherent disturbances such as intermodulation products, second and third order distortions or discrete-frequency interfering signals not operating on proper offset assignments shall be as follows: (i) The ratio of visual signal level to coherent disturbances shall not be less than 51 decibels for noncoherent channel cable television systems, when measured with modulated carriers and time averaged; and (ii) The ratio of visual signal level to coherent disturbances which are frequency- coincident with the visual carrier shall not be less than 47 decibels for coherent channel cable systems, when measured with modulated carriers and time averaged. (9) The terminal isolation provided to each subscriber terminal: (i) Shall not be less than 18 decibels. In lieu of periodic testing, the cable operator may use specifications provided by the manufacturer for the terminal isolation equipment to meet this standard; and (ii) Shall be sufficient to prevent reflections caused by open-circuited or short-circuited subscriber terminals from producing visible picture impairments at any other subscriber terminal. (10) The peak-to-peak variation in visual signal level caused by undesired low frequency disturbances (hum or repetitive transients) generated within the system, or by inadequate low frequency response, shall not exceed 3 percent of the visual signal level. Measurements made on a single channel using a single unmodulated carrier may be used to demonstrate compliance with this parameter at each test location. (11) As of June 30, 1995, the following requirements apply to the performance of the cable television system as measured at the output of the modulating or processing eyuipment (generally the headend) of the system: (i) The chrominance-luminance delay inequality (or chroma delay), which is the change in delay time of the chrominance component of the signal relative to the luminance component, shall be within 170 nanoseconds. (ii) The differential gain for the color subcarrier of the television signal, which is measured as the difference in amplitude between the largest and smallest segments of the chrominance signal (divided by the largest and expressed in percent), shall not exceed 20%. (iii) The differential phase for the color subcarrier of the television signal which is measured as the largest phase difference in degrees between each segment of the chrominance signal and reference segment (the segment at the blanking level of O IRE), shall not exceed 10 degrees. . (12) As an exception to the general provision requiring measurements to be made at subscriber terminals, and without regard to the type of signals carried by the cable television system, signal leakage from a cable television system shall be measured in accordance with the procedures outlined in Sec. 76.609(h) and shall be limited as follows: Signal leakage Frequencies limit Distance in (micro-volt/ meters (m) meter) Less than and including 54 MHz, and over 216 MHz 15 30 Over 54 up to and including 216 MHz 20 3 (b) Cable television systems distributing signals by using methods such as non-conventional coaxial cable techniques, non-coaxial copper cable techniques, specialized coaxial cable and fiber optical cable hybridization techniques or specialized compression techniques or specialized receiving devices, and which, because of their basic design, cannot comply with one or more of the technical standards set forth in paragraph (a) of this section, may be permitted to operate: Provided, That an adequate showing is made pursuant to Sec. 76.7 which establishes that the public interest is benefited. In such insta.nces, the Commission may prescribe special technical requirements to ensure that subscribers to such systems are provided with an equivalent level of good quality service. Note 1: Local franchising authorities of systems serving fewer than 1000 subscribers may adopt standards less stringent than those in Sec. 76.605(a). Any such agreement shall be reduced to writing and be associated with the system's proof-of-performance records. Note 2: For systems serving rural areas as defined in Sec. 76.5, the system may negotiate with its local franchising authority for standards less stringent than those in Sec. Sec. 76.605(a)(3), 76.605(a)(7), 76.605(a)(8), 76.605(a)(10) and 76.605(a)(11). Any such agreement shall be reduced to writing and be associated with the system's proof-of- performance records. Note 3: The requirements of this section shall not apply to devices subject to the TV interface device rules under part 15 of this chapter. Note 4: Should subscriber complaints arise from a system failing to meet Sec. 76.605(a)(6) prior to December 30, 1999, the cable operator will be required to provide a converter that will allow the system to meet the standard immediately at the complaining subscriber's terminal. Further, should the problem be found to be system-wide, the Commission may order all converters on the system be changed to meet the standard. Note 5: Should subscriber complaints arise from a system failing to meet Sec. 76.605(a)(10), the cable operator will be required to remedy the complaint and perform test measurements on Sec. 76.605(a)(10) containing the full number of channels as indicated in Sec. 76.601(b)(2) at the complaining subscriber's terminal. Further, should the problem be found to be system-wide, the Commission may order that the full number of channels as indicated in Sec. 76.601(b)(2) be tested at all required locations for future proof-of-performance tests. Note 6: No State or franchising authority may prohibit, condition, or restrict a cable system's use of any type of subscriber equipment or any transmission technology. Sec.76.609 Measurements. (a) Measurements made to demonstrate conformity with the performance requirements set forth in Sec. Sec. 76.601 and 76.605 shall be made under conditions which reflect system performance during normal operations, including the effect of any microwave relay operated in the Cable Television Relay (CARS) Service intervening between pickup antenna and the cable distribution network. Amplifiers shall be operated at normal gains, either by the insertion of appropriate signals or by manual adjustment. Special signals inserted in a cable television channel for measurement purposes should be operated at levels approximating those used for normal operation. Pilot tones, auxiliary or substitute signals, and non- television signals normally carried on the cable television system should be operated at normal levels to the extent possible. Some exemplary, but not mandatory, measurement procedures are set forth in this section. (b) When it may be necessary to remove the television signal normally carried on a cable television channel in order to facilitate a performance measurement, it will be permissible to disconnect the antenna which serves the channel under measurement and to substitute there for a matching resistance termination. Other antennas and inputs should remain connected and normal signal levels should be maintained on other channels. (c) As may be necessary to ensure satisfactory service to a subscriber, the Commission may require additional tests to demonstrate system performance or may specify the use of different test procedures. (d) The frequency response of a cable television channel may be determined by one of the following methods, as appropriate: (1) By using a swept frequency or a manually variable signal generator at the sending end and a calibrated attenuator and frequency-selective voltmeter at the subscriber terminal; or (2) By using either a multi-burst generator or vertical interval test signals and either a modulator or processor at the sending end, and by using either a demodulator and either an oscilloscope display or a waveform monitor display at the subscriber terminal. (e) System noise may be measured using a frequency-selective voltmeter (field strength meter) which has been suita.bly calibrated to indicate RMS noise or average power level and which has a known bandwidth. With the system operating at normal level and with a properly matched resistive termination substituted for the antenna, noise power indications at the subscriber terminal are taken in successive increments of frequency equal to the bandwidth of the frequency-selective voltmeter, summing the power indications to obtain the total noise power present over a 4 MHz band centered within the cable television channel. If it is established that the noise level is constant within this bandwidth, a single measurement may be taken which is corrected by an appropriate factor representing the ratio of 4 MHz to the noise bandwidth of the frequency-selective voltmeter. If an amplifier is inserted between the frequency- selective voltmeter and the subscriber terminal in order to facilitate this measurement, it should have a bandwidth of at least 4 MHz and appropriate corrections must be made to account for its gain and noise figure. Alternatively, measurements made in accordance with the NCTA Recommended Practices for Measurements on Cable Television Systems, 2nd edition, November 1989, on noise measurement may be employed. (f) The amplitude of discrete frequency interfering signals within a cable television channel may be determined with either a spectrum analyzer or with a frequency- selective voltmeter (field strength meter), which instruments have been calibrated for adeyuate accuracy. If calibration accuracy is in doubt, measurements may be referenced to a calibrated signal generator, or a calibrated variable attenuator, substituted at the point of ineasurement. If an amplifier is used between the subscriber terminal and the measuring instrument, appropriate corrections must be made to account for its gain. (g) The terminal isolation between any two terminals in the cable television system may be measured by applying a signal of known amplitude to one terminal and measuring the amplitude of that signal at the other terminal. The frequency of the signal should be close to the mid-frequency of the channel being tested. Measurements of terminal isolation are not required when either: (1) The manufacturer's specifications for subscriber tap isolation based on a representative sample of no less than 500 subscribers taps or (2) Laboratory tests performed by or for the operator of a cable television system on a representative sample of no less than 50 subscriber taps, indicates that the terminal isolation standard of Sec. 76.605(a)(9) is met. To demonstrate compliance with Sec. 76.605(a)(9), the operator of a cable television system shall attach either such manufacturer's specifications or laboratory measurements as an exhibit to each proof-of-performance record. (h) Measurements to determine the field strength of the signal leakage emanated by the cable television system shall be made in accordance with standard engineering procedures. Measurements made on frequencies above 25 MHz shall include the following: (1) A field strength meter of adequate accuracy using a horizontal dipole antenna shall be employed. (2) Field strength shall be expressed in terms of the RMS value of synchronizing peak for each cable television channel for which signal leakage can be measured. (3) The resonant half wave dipole antenna shall be placed 3 meters from and positioned directly below the system components and at 3 meters above ground. Where such placement results in a separation of less than 3 meters between the center of the dipole antenna and the system components, or less than 3 meters between the dipole and ground level, the dipole shall be repositioned to provide a separation of 3 meters from the system components at a height of 3 meters or more above ground. (4) The horizontal dipole antenna shall be rotated about a vertical axis and the maximum meter reading shall be used. (5) Measurements shall be made where other conductors are 3 or more meters (10 or more feet) away from the measuring antenna. (i) For systems using cable traps and filters to control the delivery of specific channels to the subscriber terminal, measurements made to determine compliance with Sec. 76.605(a) (5) and (6) may be performed at the location immediately prior to the trap or filter for the specific channel. The effects of these traps or filters, as certified by the system engineer or the equipment manufacturer, must be attached to each proof-of-performance record. (j) Measurements made to determine the differential gain, differential phase and the chrominance-luminance delay inequality (chroma delay) shall be made in accordance with the NCTA Recommended Practices for Measurements on Cable Television Systems, 2nd edition, November 1989, on these parameters.
