or better, to successfully complete initialization. The default value

 

mentioned is an indicative value only.

 

 

Maximum Snr Margin(dB/10)

Configured Maximum acceptable downstream Signal/Noise

 

Margin. If the Noise Margin is above this the modem attempts to

 

reduce its power output to optimize its operation. The value set by

 

the user is in dB/10, and ranges from 0 to 31 dB in 1 dB steps.

 

 

PSD MoD Enable

Conexant parameter used to enable the Mask on Demand(MoD)

 

feature in the upstream direction. It is available only for ADSL2

 

Annex A ONLY.(length = 4 bytes)

 

 

PsdMod FallBackEnable

Conexant parameter used to enable Mask on Demand (MoD)

 

fallback mode. When enabled, the system chooses MoD or the

 

base ADSL2 depending upon the upstream rate. It is avaiable only

 

for ADSL2 Annex A.(length = 4 bytes)

 

 

Max Nom PSD(dB/10)

This parameter specifies the maximum nominal transmit

 

PSD(MAXNOMPSD) level during initialization and showtime.

 

Value depends on CO MIB element settings and near end

 

transmitter capabilities and is exchanged in the G.994.1 Phase. It

 

is available only for ADSL2/ADSL2plus. Value ranges from -60 to

 

-38 in steps of 0.1 dBm/Hz.(length = 4 bytes)

 

 

Max Nom AtpPsd(dB/10)

This parameter specifies the maximum nominal aggregate

 

transmit power(MAXNOMATP) level during initialization and

 

showtime. Value depends on CO MIB element settings and local

 

capabilities and is exchanged in the G.994.1 Phase. It is available

 

only for ADSL2/ADSL2plus. Value ranges from 0 to 25.5 in steps

 

of 0.1 dBm.(length = 4 bytes)

 

 

Rate Adaptation

Defines what form of transmit rate adaptation is configured on this

 

modem. The default value mentioned is an indicative value only.

 

 

Min INP

Parameter used to specify the minimum impulse noise protection

 

for the upstream bearer channel. Supported for

 

ADSL2/ADSL2plus ONLY

 

 

US PSD Mask

This configuration parameter defines that the upstream PSD mask

 

applicable at the U C2 reference point. This MIB PSD mask may

 

impose PSD restrictions in addition to the Limit PSD mask defined

 

in the relevant Recommendation (e.g., G.992.5). It is available

 

only for Annexes J and M of ADSL2/ADSL2plus.(length = 4 bytes)
