5.3 Tree Networking
In this networking mode, several chains are connected at one or more nodes, but the
nodes do not form a ring.
Figure 5-4 describes an application example of tree networking in a mobile network
backhaul transmission. For the nodes near the BSC side, the OptiX RTN 600 adopts
1+1 configuration and the microwave capacity is 16xE1 or 1xSTM-1. For the nodes at
the network edge, the OptiX RTN 600 adopts 1+0 configuration and the microwave
capacity is 4xE1.

5.4 Fiber Ring Networking
In this networking mode, optical transmission systems form a ring through fiber
connection, and microwave transmission systems are directly connected to the ring or
indirectly connected to the ring through STM-1o or STM-1e.
Figure 5-5 shows a network with a fiber ring and a microwave link directly connected
to the ring. In this example, the optical transmission systems and the OptiX RTN 600
systems form an STM-1 ring. The ring adopts the SNCP protection mechanism.
