Command Usage
• 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 band-plan,
page 29-38).
