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 100.
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 100.
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
0 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.
