13.5.4 Insertion Ahead of RPD Based Node
If RF QAM insertion is used/envisioned in RPD scenarios, it is possible to do similar insertion configurations as we have
illustrated above in previous deployment examples/scenarios.
1. Node configured with RPD module and Forward Path Receiver, Figure 13-10.
2. Node configured with RPD module and external Forward Path Receiver,Figure 13-11.
