Installation & Operation Manual Introduction
8/11/98 12:03 System Configuration 1-13
Mixed Configuration
The Mixed Configuration, consisting of the RADring hub and the trunk
access unit is installed as part of a large network, as in the Multi-hub and
Satellite configurations, by connecting 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 connections, or in applications where
you can use existing discreet access units.
The RADring Ring In/Ring Out and repeater modules are compatible with
their stand-alone or card versions, which are used together with access units
(e.g. S-TAU). This compatibility allows both types of network components to
co-exist in the same ring. Ring In/Ring Out and repeater modules such as the
TIO, TCR, TFR, or TFC, facilitate system expansion through interconnection
to other hubs or TAUs. In a typical application, the RADring is attached to
adjacent S-TAUs and Fiber-TAUs via repeaters such as the TFR or TCR, or
converters such as the TFC. A combination of fiber or copper can be used
for expansion of the ring. Figure 1-6 depicts a mixed hub/access unit
application.
