This command disables VDSL signals at frequencies less than or equal to
640 KHz, 1.1 MHz or 2.2 MHz. Use the no form to restore the default
setting.
Syntax
lre tone {tx | rx} value
no lre tone {tx | rx}
• tx – Downstream band plan.
• rx – Upstream band plan.
• value – Index of low-end frequency range to disable.
(Options:1 - all tones on
2 - disable tones at 640 KHz and below
3 - disable tones at 1.1 MHz and below
4 - disable tones at 2.2 MHz and below)

Command Usage
• Enter this command in global configuration mode to disable the
specified low-end frequency for all VDSL ports, or in interface mode
to disable it for a VDSL port.
• This command specifies a frequency beneath which VDSL signals are
not allowed. For example, the default lower frequency bound for DS1
defined in Annex C of G.993.2 is 640 KHz. The low-end frequencies
filtered out by this command are used for common POTS or ISDN
services.
• The frequency bound specified by this command takes precedence
over that defined in the selected band plan (see lre band-plan,
page 29-4).
