Connection Setup for xDSL/IP Triple-Play Verification Tests

VDSL2, ADSL2+ and IP Triple-Play Test Set 23

Setup Line Connection

Thresholds

The Thresholds tab allows you to specify upper and lower thresholds

against which the actual measured unit/DSLAM negotiated results will be

evaluated.The described Selected Profile is composed of the current

LineMode and AccessMode selections. If LineMode is set to Ethernet, this

tab is unavailable.

The available parameters are the

following:

³ Min. Actual Bit Rate(kbps) is

minimum actual bit rate,

DownStream and UpStream.

Measured values must be greater

than these limits. For

DownStream:

³ If LineMode is set to ADSL2+,

valid values are 0

through 25000, with a default value of 4000.

³ If LineMode is set to VDSL2, valid values are 0 through 100000,

with a default value of 12000.

For UpStream:

³ If LineMode is set to ADSL2+, valid values are 0 through 1000, with

a default value of 800.

³ If LineMode is set to VDSL2, valid values are 0 through 80000, with

a default value of 6000.

³ Min. SNR Margin(dB) is minimum signal-to-noise ratio margin

DownStream and UpStream where valid values range from

through 63.5, with a default value of 5.

³ Max. Attenuation(dB) is maximum attenuation DownStream and

UpStream where valid values range from 0

through 128.0, with a

default value of 10.
