Sec. 76.601 Performance 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. Each system operator shall be prepared to show, on request by
an authorized representative of the Commission or the local franchiser,
that the system does, in fact, comply with the rules.
(b) The operator of each cable television system shall maintain at
its local office a current listing of the cable television channels
which that system delivers to its subscribers.
(c) The operator of each cable television system shall conduct
complete performance tests of that system at least twice each calendar
year (at intervals not to exceed seven months), unless otherwise noted
below, and shall maintain the resulting test data on file at the
operator's local business office for at least five (5) years. The test
data shall be made available for inspection by the Commission or the
local franchiser, upon request. 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
[[Page 548]]
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 distant
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).
(d) Successful completion of the performance tests required by
paragraph (c) 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 of the
local franchiser to secure compliance with the technical standards.
(e) The provisions of paragraphs (c) and (d) 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. 73.603 and
Sec. 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
[[Page 549]]
than the two years prescribed in Sec. 76.614.
Note: Prior to requiring any additional testing pursuant to
Sec. 76.601(d), 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.
