Figure 2-7 Satellite Configuration
Mixed
Configuration
The Mixed RADring hub and trunk access unit configuration is installed as
part of a large network, as in the Multi-hub and Satellite configurations, by
connecting additional hubs and IEEE 802.5 compatible access units.
This configuration is useful in applications where certain locations of the ring
do not justify the placement of a hub, due to the small number of
workstations that require connecting or alternatively where access units have
already been installed in order to use existing equipment.
The RADring ring in/ring out and repeater modules are totally compatible
with their stand-alone or card versions which are used together with access
units (S-TAU or Fiber Optic TAU), allowing both types of network
components to coexist in the same ring. Modules (Ring In/Ring Out and
Repeater Modules) such as the TIO, TCR, TFR or TFC, facilitate system
expansion through the interconnection of other hubs or TAUs. In a typical
application, the RADring is attached to adjacent S-TAUs and Fiber Optic
TAUs via repeaters such as the TFR or TCR, or converters such as the TFC.
