Ethernet
A network communications system developed and standardized by Digital, Intel, and
Xerox, using baseband transmission, CSMA/CD access, and logical bus topology.
This industry-standard protocol is specified by ISO 8802-3 ANSI/IEEE Standard
802.3.
Ethernet station
An addressable node on an Ethernet network capable of transmitting and receiving
data. An Ethernet station must contain a MAC.
failover
The feature that causes a failed link to automatically reconfigure to a redundant or
“backup” link.
FDDI port connector type
A variable that specifies the type of port. The four different port connector types are:
A - The port is a dual attachment station or concentrator that attaches to the primary
in and the secondary out when attaching to the dual ring.
B - The port is a dual attachment station or concentrator that attaches to the second-
ary in and the primary out when attaching to the dual ring.
S - Either one port in a single attachment station, or one port in a single attachment
concentrator.
M - A port in a concentrator that serves as a master to a connected station or concen-
trator.
FDDI station
A node on an FDDI ring capable of transmitting, receiving, and repeating data. A
station has one instance of SMT, at least one instance of PHY and PMD, and an
optional MAC entity.
Fiber Distributed Data Interface (FDDI)
A set of ANSI/ISO standards that define a high-bandwidth (100-Mb/s), general-pur-
pose, shared, local area network (LAN) connection between computers and periph-
eral equipment in a timed-passing, dual ring-of-trees configuration.
