Because the trunkline can vary greatly from one Data Highway II
configuration to the next, you have to construct your own trunkline. The
trunkline actually consists of a number of cable segments. Each trunkline
segment must be a minimum of 30 feet long and connect to the taps of
two neighboring nodes on the trunkline (Figure 3.5).
Three major tasks are required in constructing the trunkline:
Cutting the cable into segments of appropriate length.
Attaching the plugs on the ends of the cable segments.
Plugging the trunkline segments into the taps.
Cutting the Cable
Use RG-11-type coaxial cable for the trunkline. When cutting the cable
segments, make them long enough to route them from one tap to the next
with sufficient slack, according to the guidelines in “Planning Your
Cabling Configuration.”
