11.7.5 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

DESCRIPTION
This is the minimal electrical length of the cable between the CO and Cabinet. Type the
electrical length in multiples between 0~511 of 0.5 dBm.
These parameters define a cable model that is used to describe the frequency dependent
loss of exchange-side cables.
This defines the assumed minimum usable received PSD mask (in dBm/Hz) for exchange
based services, used to modify parameter DPBOFMAX defined below. Enter from 0 to 255
to set the PSD to 0~-127.5 dBm/Hz in steps of -0.5 dBm.
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 link
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.
