Min L2 Rate
Set the minimum transfer rate (in Kilobits per second) that is permitted while the
port is in the L2 power mode. The supported range is 32~4096 Kbps in 4 Kbps
increments. If you enter a number that is not a multiple of 4, the system uses the
next lower multiple of 4. If you enter 39, for example, the system will use 36. Set
this to 0 to have the system automatically assign a value.
L0 to L2 Rate
Set the down stream transfer rate (in Kilobits per second) that serves as the
threshold for whether the port is to use the L0 or the L2 power mode. The
system changes from L0 mode to L2 mode when the downstream transfer rate
stays below this threshold for
L0 Time
. The system changes back from L2
mode to L0 mode when the downstream transfer rate goes above this threshold.
This rate must be less than or equal to one half of the
Min L2 Rate
and at least
16 Kbps. Set this to 0 to have the system automatically assign a value.
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
Mask0
represents tones 0~31.
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.
You can only have one range of upstream carrier tones enabled. For example,
you would not be able to use 0x00000080 to disable only upstream carrier tone
24 because it would leave two ranges of tones enabled (0~23 and 25~31).
DSCarrier(32~255)
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.
DSCarrier(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.
