Identify Cable System Components

About direct connection
Connect devices directly to the trunk line only if you can later remove the
devices without disturbing communications on the cable system.
About open-style connectors
Open-style connectors come in two primary varieties:
•
five-position (5 pin linear plug)
•
ten-position (10 pin linear plug)
Ten-position connectors provide easier daisy-chaining because there is an
independent wire chamber for each wire (entering cable and exiting cable).
IMPORTANT
If a device provides only fixed-terminal blocks for its
connection, you must connect it to the cable system by a
drop line. Doing this allows you to remove the device at the
tap without disturbing communications on the cable
system.
