Chapter 52 ADSL Commands
The hexadecimal digit is converted to binary and a '1' masks (disables) the corresponding tone. Disabling a carrier tone turns it off so the system does not send data on it.
This command displays or sets masks for upstream carrier tones from 0 to 63. Masking a carrier tone disables the use of that tone on the specified DSL port. Use this command to have the system not use a DSL line’s tones that are known to have a high noise level. The most significant bit defines the lowest tone number in a mask.
The most significant bit defines the first tone sequentially. For example, in <m0>, 0x00000001 means tone 31. For example, you could use 0xffff0000 for <m0> to disable upstream carrier tones 0~15 and leave tones 16 ~ 31 enabled.
The following example disables upstream carrier tones 0~15 for DSL port 5.

ras> adsl uscarrier 5 ffff0000 00000000
The following example displays the results.

Syntax:
ras> adsl dscarrier0 <port number> [<m1> <m2> <m3> <m4> <m5> <m6> <m7>]
where
<m1> - <m7> | = | The downstream carrier tones to be masked (disabled). Each |
|
| <mx> can use up to 8 hexadecimal digits (0~ffffffff). Each |
|
| <mx> represents 32 carrier tones (each hexadecimal digit |
|
| represents 4 tones). |
<m1> | = | tones 32~63 |
<m2> | = | tones 64~95 |
<m3> | = | tones 96~127 |
<m4> | = | tones 128~159 |
<m5> | = | tones 160~191 |
<m6> | = | tones 192~223 |
<m7> | = | tones 224~255 |
The hexadecimal digit is converted to binary and a '1' masks (disables) the corresponding tone. Disabling a carrier tone turns it off so the system does not send data on it.
