NetWare
Novell’s network operating system, which provides the ability to transparently
share services across dissimilar platforms. Uses the NetWare Core Protocol
(NCP), Internetwork Packet Exchange (IPX), and Sequential Packet Exchange

RJ-45 Connector
Most common terminator for twisted-pair wiring.
Shielded Twisted-Pair
100W Category 5 twisted-pair wire covered with an external aluminum-foil or
woven-copper shield designed to reduce excessive noise pick up or radiation. The
STP cable refered to in this manual is also sometimes called screened twisted-pair
(ScTP). Its impedance is 100Wand has the same pin assignment as UTP. This
cable should not be confused with the older 150Wcable type designed by IBM.
Unshielded Twisted-Pair
Cable composed of two insulated wires twisted together to reduce
electrical interference; used in common telephone cord.
