The H80B Personal Hub may also be used as a stand-alone
network for a local multi-user system such as shown in the figure.
The BNC port is used to support devices connected via ThinNet,
while the RJ-45 ports support up to eight user devices connected via
twisted pair. Full-length Ethernet segments are supported on all
segments. In this application, the "Up-Link" switch is in the straight-
through or = position so that the switchable up-link port is a user
port, not an up-link to another hub.
