VDSL C OMMANDS

• Using a HAM band mask prevents interference with other systems
(e.g., amateur radio) that use narrow band transmission in the VDSL
frequency band. The selected frequency range will not be used to
transmit data on the VDSL line. You may need to specify a mask if
required by local regulations or if specific incidents of interference are
reported within a service area.
• The following table lists HAM band notches for general usage types.
