General
There are five types of Token Ring RADring modules:
•
Lobe Access modules
•
Ring In/Ring Out modules
•
Elementary Bridge modules.
•
System modules
Lobe access modules enable Token Ring stations to be connected to the
Token Ring using a variety of media types; Ring In/Ring Out modules enable
the network to be expanded to adjacent hubs.
Note
Ring-In/Ring-Out modules require that the ring's leftmost module be assigned
as Ring-In and the rightmost be assigned as Ring-Out.
System modules provide features to the entire hub/network, such as network
management and jitter attenuation; Elementary Bridge modules connect
local or remote networks to the central LAN.
The RADring provides flexibility in network design. Typical system
configurations can be broken down into the following:
•
Stand-alone hub
•
Multi-hub
•
Satellite
•
Mixed RADring hub and access units
•
Multiple-ring hub.
Four types of Ethernet RADring modules are available:
•
Multi port repeater (for RADringII hubs only)
•
Independent multi port repeater
•
System modules
•
Extension modules.
An Ethernet module enables an Ethernet station to be connected to the
Ethernet network using a variety of media types.
System modules provide features to the entire hub/network, such as network
managment.
Extension modules connect WAN links to the central LAN.
