Chapter 52 ADSL Commands

where

<max

nominal

= -400 ~ 40 (unit of measure is 0.1dBm/Hz)

psd>

 

 

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.

ras> adsl usnompsd 7 -100

52.1.12 DSL Port Downstream PSD Command

Syntax:

ras> adsl dsnompsd <portNo> [<max nominal psd>]

where

 

<max nominal

= -400 ~ 40 (unit of measure is 0.1dBm/Hz)

psd>

 

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.

ras> adsl dsnompsd 7 -100

52.1.13 DSL Port Upstream Carrier Command

Syntax:

ras> adsl uscarrier <portNo> [<m0> <m1>]

where

<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.
