Configuring FFT

The fft setup command can be used to configure the FFT processor on the BCM3138/
BCM3140 chip set or to display the current FFT processor configuration.

Configuring the FFT Processor

Use the fft setup command, in Privileged EXEC mode, to configure the FFT
processor, as follows:
MOT#fft setup <Slot/Port> [sample {<256-2048>} mode {Tap-in} window
{blackman | blackman-harris | hamming | hanning | rectangular}]
where:

Displaying the FFT Processor Configuration

Use the fft setup <Slot/Port> command, without any additional arguments, to display
the current FFT processor configuration for a particular port on a particular CMTS
module, as follows:.
MOT#fft setup <Slot/Port>
