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)
