Abstract: Full Duplex (FDX) enhanced node deployment may be provided. First, a first device level may be provided comprising a first plurality of FDX enhanced nodes. The first plurality of FDX enhanced nodes may comprise a first FDX enhanced node and a second FDX enhanced node. The first plurality of FDX enhanced nodes may be operated in a first mode. Next, a second device level may be provided comprising a third FDX enhanced node. The second device level may be upstream from the first device level. The third FDX enhanced node may be operated in a second mode. Then an input port of the first FDX enhanced node and an input port of the second FDX enhanced node may be provided with a same type of input that is being provided to an input port of the third FDX enhanced node. The first plurality of FDX enhanced nodes may then be switched from being operated in the first mode to being operated in the second mode.
