B.5.1 Definitions
Backbone
A coax segment with hubs, possibly file servers.
Cascade
A method of interconnecting hubs using their ports rather than their
stacking connectors.
Link Segment
A length of twisted-pair or fiber cable joining a pair of devices in a star
topology (e.g., two hubs or a hub and a station).
Populated Segment
A coax segment to which multiple devices are attached: maximum 100
transceivers for thick coax and 30 devices (e.g., stations and hubs) for thin
coax.
Coax Segment
An electrically continuous length of coax cable with a terminating resistor
at each end.
Stack
A method of interconnecting multiple hubs so that multiple hubs appear
as one large hub or repeater to the network.
Unpopulated Segment or Inter-Repeater Link (IRL)
Relevant to coax networks only.
A coax segment with one repeater or hub at each end and no other
attached devices is an IRL.
