rate. In the case that RADSL is not present, the

value will be 0.

Min Upshift Time(sec)

Minimum time that the current margin is above

UpshiftSnrMgn, before an upshift occurs. In the

case that RADSL is not present, the value will be

0.

Min Dnshift Time(sec)

Minimum time that the current margin is below

DownshiftSnrMgn, before a downshift occurs. In

the case that RADSL mode is not present, the

value will be 0.

Fast Min Tx Rate(bps)

Configured Minimum Transmit rate for 'Fast'

channels, in bps. Also refer to

'adslAturConfRateChanRatio' for information

regarding RADSL mode and ATU-C transmit

rate for ATU-R receive rates.

Intl Min Tx Rate(bps)

Configured Minimum Transmit rate for

'Interleave' channels, in bps. Also refer to

'adslAturConfRateChanRatio' for information

regarding RADSL mode and to ATU-C transmit

rate for ATUR receive rates.

Fast Max Tx Rate(bps)

Configured Maximum Transmit rate for 'Fast'

channels, in bps. Also refer to

'adslAturConfRateChanRatio' for information

regarding RADSL mode and to ATU-C transmit

rate for ATUR receive rates.

Intl Max Tx Rate(bps)

Configured Maximum Transmit rate for

'Interleave' channels, in bps. Also refer to

'adslAturConfRateChanRatio' for information

regarding RADSL mode and to ATU-C transmit

rate for ATU-R receive rates.

Max Intl Delay(ms)

Configured maximum Interleave Delay for this

channel. Interleave delay applies only to the

interleave channel and defines the mapping

(relative spacing) between subsequent input

bytes at the interleaver input and their placement

in the bit stream at the interleaver output. Larger

numbers provide greater separation between

consecutive input bytes in the output bit stream,

allowing for improved impulse noise immunity at

the expense of payload latency

MSG Min Us

Configures upstream overhead channel

bandwidth.This feature is not supported by

DSLPHY as yet.

Minimum Snr

Margin(dB/10)

Atuc Configured Minimum Signal/Noise Margin.

This is the Noise Margin, the modem must

achieve with a BER of 10 to the power -7 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
