where
This command displays or sets the upstream maximum nominal transmit PSD (Power Spectral
Density).
The following example sets the upstream maximum nominal transmit PSD for port 7 to -10
dBm/Hz.
52.1.12 DSL Port Downstream PSD Command
Syntax:
ras> adsl dsnompsd <portNo> [<max nominal psd>]
where
This command displays or sets the downstream maximum nominal transmit PSD (Power
Spectral Density).
The following example sets the downstream maximum nominal transmit PSD for port 7 to -10
dBm/Hz.
52.1.13 DSL Port Upstream Carrier Command
Syntax:
ras> adsl uscarrier <portNo> [<m0> <m1>]
where
<max nominal
psd>
=
-400 ~ 40 (unit of measure is 0.1dBm/Hz)

<m0>,<m1> =
The upstream subcarriers to be masked (disabled). Each
<mx> can use up to 8 hexadecimal digits
(00000000~ffffffff). Each <mx> represents 32 carrier tones
(each hexadecimal digit represents 4 tones).
<m0> = tones 0~31
<m1> = tones 32~63
The hexadecimal digit is converted to binary and a '1'
disables the corresponding tone. Disabling a carrier tone
turns it off so the system does not send data on it.
