ModPhase

Conexant parameter to monitor the status of MoD

Atuc TSSpsUs

This parameter provides the Upstream Transmit Spectrum

Shaping parameter expressed as the set of break points

exchanged during G994.1. Each breakpoint consists in a

subcarrier index and the associated shaping parameter.

Value of this parameter is in range 0 - 127, in multiples of

-0.5 dB. 127 is a special value indicating the subcarrier is

not transmitted. It is available only for ADSL2/ADSL2plus.

GainspsUs

This parameter defines the upstream gains allocation table

per subcarrier. It is an array of integer values in the 0 to

4093 range for subcarriers 0 to NSCus-1. The gain value

is represented as a multiple of 1/512 on linear scale. It is

supported for ADSL2/ADSl2plus only.

GsSeltInfoValid

Indicates the information validity for the SELT operation

conducted on the Xcvr.

GsSeltLoopLen (in Feet)

Indicates the LOOP Length in Feet once when the SELT

information is valid on the Xcvr.

GsSeltLoopEnd

Indicates whether the loop is short or open once when the

SELT information is valid on the Xcvr.

GsSeltLoopGauge

Indicates the LOOP wire gauge information once, when

the SELT information is valid on the Xcvr.

GsSeltUpShannonCap (in bps)

Indicates the upstream shannon capacity once, when the

SELT information is valid on the Xcvr.

GsSeltDownShannonCap (in bps)

Indicates the downstream shannon capacity once, when

the SELT information is valid on the Xcvr.

AtucGsSeltInbandNoise

512 values that indicate inband noise length in dBM/Hz,

covering both bands from 0 to 1.1 MHz.

AtucGsSeltTerminationResp

180 discrete values that indicate termination response

magnitude from 0 to 18Kft.

AtucGsSeltUpMgnAtRate

300 values that indicate SNR margin in dB/10 at a

particular rate are provided, at 100K increments, up to 15

Mbps.

AtucGsSeltDownMgnAtRate

300 values that indicate SNR margin in dB/10 at a

particular rate are provided, at 100K increments, up to 15

Mbps.

Delt HLINSCus

The DELT-related parameter that provides the scale factor

to be applied to the upstream Hlin (f) values. (Not available

for ADSL and ADSL2plus)

Delt HLOGMTus

The DELT-related parameter that provides the number of

symbols used to measure the upstream Hlog (f). (Not
