Question 2

Under FCC Part 76, what is the maximum permissible signal leakage level for cable systems operating above 54 MHz?

Accepted Answer

10 microvolts/meter at 100 feet

Answer

FCC Part 76.605 limits cable signal leakage to 10 microvolts/meter measured at 100 feet from any point in the cable plant for frequencies above 54 MHz, protecting aeronautical frequencies.

Question 3

What is the purpose of the FCC's cumulative leakage index (CLI) requirement for cable operators?

Accepted Answer

To provide a statistical measure of signal leakage across the entire cable plant, ensuring aggregate interference to over-the-air services remains below regulatory thresholds

Answer

The CLI is a statistical measurement combining all individual leakage measurements across a cable system into a single index value, which must remain below 64 under FCC regulations to protect aeronautical and other over-the-air services.

Question 4

Which ANSI/SCTE standard defines minimum technical requirements for cable television equipment and system performance?

Accepted Answer

ANSI/SCTE 40

Answer

ANSI/SCTE 40 specifies the technical requirements for cable television equipment and systems, covering signal levels, distortion limits, and other performance parameters.

Question 5

What does the FCC's must-carry rule require of cable operators?

Accepted Answer

Cable systems must carry all local broadcast television stations that request carriage on the cable system

Answer

Under FCC must-carry rules, cable systems with more than 12 channels must carry all local commercial and noncommercial educational broadcast TV stations that assert mandatory carriage rights.
