1. A method for Full Duplex (FDX) amplification in a FDX data over cable network, the method comprising:
receiving downstream signals via a first port;
recovering, from the downstream signals received via the first port, information regarding a requested sub-band directional assignment for FDX allocated spectrum:
using a first downstream digital filter having a passband corresponding to a first FDX sub-band of the FDX allocated spectrum to separate, from the downstream signals received via the first port, downstream signals in the first FDX sub-band of the FDX allocated spectrum;
receiving upstream signals via a second port;
using a first upstream digital filter having a passband corresponding to the first FDX sub-band of the FDX allocated spectrum to separate, from the upstream signals received via the second port, upstream signals in the first FDX sub-band of the FDX allocated spectrum; and
in accordance with the requested sub-band directional assignment for the FDX allocated spectrum, selectively amplifying and retransmitting either:
the downstream signals in the first FDX sub-band via the second port; or
the upstream signals in the first FDX sub-band via the first port.
