Glossary Attachment Beacon Broadcast Bypass Canonical order CDDI Glossary 1 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.

Glossary
Attachment
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.
Beacon
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.
Broadcast
A packet delivery system that delivers a copy of a given packet
to all hosts that attach to it.
Bypass
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.
Canonical order
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.
CDDI
Copper Distributed Data Interface.
FDDI over twisted-pair
copper wire.
