The service planning information contains all the parameters required for configuring the NE data.
Overall Planning Information
- As shown in Figure 1, all radio equipment is included into three subnets: subnet 1 (10.3.1.0/24), subnet 2 (10.3.2.0/24), and subnet 3 (10.3.3.0/24). The IP addresses of the radio equipment in the same subnet
are on the same network segment.
- Communication between radio equipment in a subnet is implemented based on the L2 DCN solution. DCN communication between subnets is implemented based on L3 IP forwarding.
- Radio links comprised of the OptiX RTN 900 NEs use DCC channels to
transmit DCN information.
- To prevent loops in an L2 DCN and further prevent broadcast storms, the STP/RSTP protocol needs to be enabled for a switch that is connected to the L2 DCN.
