Stand-alone Hub Configuration
The Stand-alone hub, installed as a single centralized access center, provides
up to 80 Token Ring lobe connections (without RI/RO modules). In the
Stand-alone hub configuration, RADring can function as a single active
central hub (i.e., a central hub that is not connected to another TAU, MAU
or hub) or as multiple, separate rings through termination of access modules
(see Figure 1-2).
The hub's back-up path is used to complete the ring without compromising
the ring fault protection.
