13.7.5 VDSL2 Line Profile Setup > RFI Band
Click the Modify link next to the RFI BAND field in the VDSL2 Line Profile Setup screen
to open the screen as shown next. Use this screen to specify the RFI bands through which the
system and VDSL CPE devices should avoid transmitting data according to your location. See
RFI (Radio Frequency Interference)
342
DESCRIPTION
This defines the minimum frequency from which the DPBO shall be applied.
Enter from 0 kHz to 8832 kHz in steps of 4.3125 kHz.
This defines the maximum frequency at which DPBO may be applied. Enter from
138 kHz to 29997.75 kHz in steps of 4.3125 kHz.
DPBOEPSD (Assumed Exchange PSD Mask) defines the PSD mask that is
assumed to be exchanged at CO. Use this graph to view PSD level to frequency
relationship. The horizontal is frequency in MHz and vertical is power level in
dBm/Hz.
Either use a pre-defined PSD mask (psd_co, psd_flat, psd_cab_ansi,
psd_cab_etsi, psd_exch_etsi, or psd_exch_ansi) or select Custom to have
the breakpoints and PSD levels configured in the bottom of the screen updated
to this DPBOEPSD graph.
This index number identifies each incremental break point.
A tone is a sub-channel of a VDSL band. DMT divides VDSL bands into many
4.3125 kHz tones.
Enter an increased number (than previous row) from 0 to 4096 in this field that is
also the horizontal of the DPBOEPSD graph.
This read-only field displays a frequency that equals the tone index multiple
4.3125 dBm/Hz. This field automatically calculates after a Tone Index value is
entered.
Enter the PSD level for the Y-axis of DPBOEPSD graph.
Click Apply to save the changes in this screen to the system's volatile memory.
The system loses these changes if it is turned off or loses power, so use the
Config Save on the navigation panel and then the Save button to save your
changes to the non-volatile memory when you are done configuring.
Click Cancel to reset the fields to your previous configuration.
