2.1 Overview
The Networking Hub installs easily for use in a home, office, or lab environment,
requiring no special rack cabinets or wiring-closet apparatus. This compact,
standard physical-layer Ethernet hub operates independently of all software.
Simple and inexpensive to use, the Hub is ideal for networking a multi-system
home or office using 10BASE-T twisted-pair cabling. The front panel has eight
shielded twisted-pair ports, and the back panel has a 120-VAC power supply outlet.
Perfect for small-to-medium-size home, office, or lab environments (two to eight
users), the Hub helps you build an independent Ethernet network. It operates as a
self-sufficient unit to provide 10BASE-T Ethernet connectivity for local users and
devices. You can easily expand small, independent networks by cascading hubs.
Expand your network for demonstrations or presentations over the network. Or
insert this handy piece of 10-Mbps Ethernet test equipment into the network to
provide a test port, and then remove it after you’re finished testing. It takes up
minimal space and uses minimal power, plus it’s rugged enough to be carried in a
coat pocket for emergencies.
Whether you place it on a table or mount it on a shelf, the hub fits easily into the
home environment. All of the wiring connectors are in the same plane so that
wiring space is neat and minimal. The external power supply conveniently plugs
into any available AC wall receptacle or power strip.
Eight RJ-45 ports support connection of up to eight workstations or other network
devices over full-length 10BASE-T cable segments. The hub fully complies with the
IEEE 802.3 specification for repeater functionality by performing signal
amplification, re-timing data packets, and re-generating preamble bits for each
packet received. Detecting collisions, extending collision fragments, and
automatically partitioning and reconnecting individual ports keep problems on
one LAN segment from causing downtime elsewhere on the network.
