the system chooses MoD or the base ADSL2

depending upon the downstream 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 -

40 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)

DS PSD Mask

This configuration parameter defines that the

downstream 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). (length = 4

bytes).

GsAnnexCOlToCxSwitc

Conexant parameter that is used to configure

the switching point between DBM-OL and

XOL.(length = 4 bytes)

GsAnnexCSwitch

Conexant parameter that is used to configure

the switching point between Annex C and

G.Span (IFM) and between Annex C and

G.Span Plus.(length = 4 bytes)

GsAnnexCToUqSwitch

Conexant parameter that is used to configure

the switching point between Annex C and

G.Span Plus SUQ.(length = 4 bytes)

Min SnrMgnTime(sec)

This parameter indicates the time when the snr

margin violation is allowed. After this time

expires and current snr is less than min snr, the

DSL line is dropped by the APIs.

Customer ID

This parameter indicates the customer ID.

GsMPsdMaskType

Conexant parameter that selects the PSD mask

option to be used for Adsl2M.

GsSeltLoopGauge

This parameter should be set to the expected

loop gauge.

Rate Ratio

This parameter specifies the latency rate for

both channels in a dual latency configuration.

This parameter must be set the parameter to a

value greater than 0 and less than 100.

Target Snr

Margin(dB/10)

Noise Margin the modem must achieve with a

BER of 10 to the power 7 or better to

successfully complete initialization

Dnshift

SnrMargin(dB/10)

Configured Signal/ Noise Margin for rate

downshift. If the noise margin falls below this

level, the modem should attempt to decrease its

transmit rate. In the case that RADSL mode is

not present, the value will be 0.

Upshift

SnrMargin(dB/10)

Configured Signal/ Noise Margin for rate upshift.

If the noise margin rises above this level, the

modem should attempt to increase itís transmit
