Multi-hub Configuration
The Multi-hub configuration is defined as a number of hubs connected via
Ring-In/Ring-Out modules, for expanding the ring size. Ring In/Ring Out
modules and repeaters, such as the TIO, TFC, TCR or TFR, enable expansion
of the system through connection to other hubs or TAUs. Detailed
application information for each of the RI/RO and repeater modules is
provided in Chapter 2. Figure 1-4 depicts a multi-hub application.
