Cable systems monitored

The FCC has announced the results of a recent project to enforce its
cable television leakage standards.  In March, 1993, the
Commission's Enforcement Division focused on cable systems which
could pose a danger to public service radio communications, such as
aeronautical.

According to the Commission, the March sweep included monitoring 321
cable TV systems, visiting eight systems to ''discuss operator
measurements,'' and the closing down of one system for violating the
FCC's Cumulative Leakage Index (CLI) limit.  This project was in
addition to the FCC's ongoing monitoring by its field offices
nationwide.

In addition, the FCC sent letters to 1,550 cable TV operators,
issued 112 complimentary letters to ''clean'' systems, and issued 73
violation letters.  The effort was directed at all areas of the
country, the Commission said.

The system which was closed was found to have a small number of
significant leaks, according to the FCC's Jeffrey Young.  Most
system violations of the CLI are due to the additive effect of a
large number of small leaks, Young said.

The FCC plans another monitoring project later this year, on a
random basis, to gauge the effect of its enforcement and education
efforts, Young said.
