Local Tap
Each node on a Data Highway II link requires a local tap. Each local tap
has two trunkline jacks, a dropline jack, and a cap for covering the
dropline jack when you do not have a dropline connected. With each
local tap we also ship (Figure 3.2):
Two cable plugs for connecting the trunkline cables to the trunkline
jacks on the tap.
A dropline cable assembly (24 inches) for connecting a node interface
to the dropline jack on the tap.
