Chan Perf CU

The far-end user total cell count performance

parameter is a count of the total number of cells

in the ATM Data Path delivered at the V-C (for

ATU-C) or TR (for ATUR) interface. (Not

available for ADSL)

Chan Perf BE

The far-end idle bit error count performance

parameter is a count of the number of bit errors

in the idle cell payload received in the ATM Data

Path at the far-end. (Not available for ADSL)

Overhead Channel

Indicates the Overhead Channel. This feature is

not supported by DSLPHY as yet.

System Vendor ID

Indicates the Vendor ID as inserted by the ATU-

R in the Embedded Operations Channel(ADSL).

Typically identiies the ATU-R system integrator

which usually refers to the vendor of the smallest

field-replaceable unit. ATU-R System Vendor ID

may not be the same as ATU-R G.994.1 Vendor

ID. For ADSL2, provides the Vendor ID as

inserted by the ATU-R in the Overhead

Messages. It is not available for ADSL. This is

string of 8 octets containing 2 octet country

code , 4 octet vendor id and 2 octet vendor

revision number.

ATU-R Self Test

Result

Defines the ATU-R selftest result. The most

significant octet is: 00 hex if the self-test passed

or 01 hex if the self-test failed. Interpretation of

the other octets is vendor discretionary and can

be interpreted in combination with G.994.1 and

system Vendor IDs.

ATUR G9941 Vendor

Indicates the Vendor ID as inserted by the ATU-

R in the G.994.1 CLR message.The G.994.1

Vendor ID typically identifies the vendor of the

ATU-R G.994.1 functionality. This is string of 8

octets containing 2 octet country code , 4 octet

vendor id and 2 octet vendor revision number.

Atur ACTPSDds

(dB/10)

This parameter defines the average downstream

transmit power spectrum density over the used

subcarriers delivered by the ATU-C at the U-C

reference point, at the instant of measurement.

It's value ranges from -90 to 0, in 0.1 dB/Hz

steps. It is available only for ADSL2/ADSL2plus.

BitSwapCount

This Conexant parameter indicates the bit swap

count. It can read only in data mode

PSDMaskMode

This conexant parameter that indicates the

actual PSD Mask currently being used by ATU-R

Gain Spsds

This parameter defines the downstream gains

allocation table per bin. It is supported for

ADSL2/ADSl2plus only.

Atur TSSpsds

This parameter provides the Downstream

Transmit Spectrum Shaping parameter

expressed as the set of break points exchanged

during G994.1. 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.

Delt HLINSCds

The DELT-related parameter that provides the

scale factor to be applied to the downstream Hlin

(f) values. (Not available for ADSL and

ADSL2plus)

Delt HLOGMTds

The DELT-related parameter that provides the

number of symbols used to measure the

1 2 ... 257 258 259 260 261 262 263 264 265 266 267 ... 602 603
