The capability of a station or concentrator (or FDDI hub) for
connection into an FDDI network. Stations and concentrators
are classified as dual attachment, single attachment, or null
attachment.
A special type of frame transmitted when a station detects a
logical problem on the ring. It is automatically transmitted
during the ring initialization sequence when the claim token
process does not finish in the time allotted for it. The beacon
process can indicate either a station hardware or software
failure.
A packet delivery system that delivers a copy of a given packet
to all hosts that attach to it.
The ability of a node to optically isolate itself from the FDDI
network while maintaining the continuity of the cable plant.
See also Optical bypass.
The agreed upon bit order of transmission. Canonical
addressing is when the least significant bit of the most
significant byte is always transmitted first. The FDDI hub's
LLC (logical link control) address appears in canonical order
when the show sid command is issued.
Copper Distributed Data Interface. FDDI over twisted-pair
copper wire.
