SMART LOBE ACCESS UNIT
2. Introduction
2.1 Description
The Smart Lobe Access Unit allows connection of
two or four token-ring workstations to a single lobe.
Token-ring-network flexibility is increased by
enabling users to expand the topology in a more
cost-effective way. Cabling needs and installation
costs are reduced by allowing workstations to be
added to the ring without the need for additional
lobe cables to the central hub.
Wire-fault detection, which senses any short, open,
or illegal impedance in the main lobe connection, is
incorporated. If a fault is detected, the Smart Lobe
Access Unit deinserts all connected workstations.
The Smart Lobe Access Unit is powered from an
external DC power adapter via modular power jack,
or via the MAIN connector. In the latter case, 6-wire
cabling is required.
There are four models—two- and four-port versions
for either ordinary UTP cabling or "screened" UTP
cabling. "Screened" UTP has some shielding, but has
the same electrical characteristics as regular UTP
