Figure 2.5 shows a more detailed view of the T-connector, plug connectors,
jack connector and the 15-socket connector, and how they connect the
network together.
Important: You must assemble the T-connector only as shown.

The T-connector has two jack legs and a plug leg. A plug connector from
the 1770-XG connector kit attaches to each of the jack legs, and the jack
connector from the kit attaches to the plug leg.
A dropline attaches to one of the plug connectors, and the trunkline
attaches to the other plug connector. The trunkline also attaches to the
jack connector.
The 15-socket connector attaches to the dropline and then plugs into the
node interface module.
The terminators plug into the T-connector. You need to install two
terminators (one plug terminator and one jack terminator) for a complete
DH or DH+ cable system. If you order more than one 1770-XG connector
kit, you will have extra terminators. See the next section for more
information about terminators.
