Node Units
This section describes an example of node units used for communication between an
O&M software and the nodes in a network.
A PC workstation loaded with the O&M software and configured with a modem can be
connected to all nodes that have an RCC (or RCU) and communicate with other units in
connected W-nets and F-nets.
Figure 5-4 shows an O&M workstation connected to an F-net, which is also connected
to two W-nets.

The fibers between the BMU and the FOR units are used for both RF transmission and
network communication.
An internal backbone W-net in the BMU interconnects the FON units.
The two FOR units are also included in two W-nets together with two additional
repeaters in each of these W-nets.
The O&M workstation in Figure 5-4 can communicate with any of the seven units (one
BMU and six repeaters) included in the F-nets and W-nets.
