Chapter 16 xDSL Port Setup
IES-1248-51V User’s Guide

Use this part of the screen to mask carrier tones. Masking a carrier tone disables the use
of that tone on the ADSL port. Do this to have the system not use an ADSL line’s tones
that are known to have a high noise level. Each mask can use up to 8 hexadecimal digits
(00000000~ffffffff). Each hexadecimal digit represents 4 tones. The hexadecimal digit is
converted to binary and a '1' masks (disables) the corresponding tone. The most
significant bit defines the lowest tone number in a mask.
USCarrier (0~63) Mask0 represents tones 0~31.
Mask1 represents tones 32~63.
The most significant bit defines Tone 0. In other words, 0x00000001
means tone 31. For example, you could use 0xfffff000 to disable
upstream carrier tones 0~19 and leave tones 20 ~ 31 enabled.

Mask1 represents tones 32~63
Mask2 represents tones 64~95
Mask3 represents tones 96~127
Mask4 represents tones 128~159
Mask5 represents tones 160~191
Mask6 represents tones 192~223
Mask7 represents tones 224~255
For example, use 0x01000000 in Mask2 to disable downstream
carrier tone 71. Use 0x03000000 in Mask2 to disable downstream
carrier tones 70 and 71.

(256~511)
Mask0 represents tones 256~287
Mask1 represents tones 288~319
Mask2 represents tones 320~351
Mask3 represents tones 352~383
Mask4 represents tones 384~415
Mask5 represents tones 416~447
Mask6 represents tones 448~479
Mask7 represents tones 480~511
For example, use 0x00001000 in Mask1 to disable downstream
carrier tone 307. Use 0x0000f000 in Mask1 to disable downstream
carrier tones 304 to 307.
Apply Click Apply to save your changes to the IES-1248-51V’s volatile
memory. The IES-1248-51V loses these changes if it is turned off or
loses power, so use the Config Save link on the navigation panel to
