DAS-3626 VDSL2 Switch User Manual
Parameter
Description
Downstream/Upstream
Target SNR Margin
Configure the target amount of increased noise that tolerated while maintaining the
designed BER (bit error rate). If the SNR Margin is increased, bit error rate
performance will improve, but the data rate will decrease. Conversely, if the SNR
Margin is decreased, bit error rate performance will decrease, but the data rate will
increase. This field is to be set for the maximum upstream rate SNR Margin and is
to be set in dB. (decibals)
Downstream/Upstream Min
SNR Margin
Configure the minimum amount of increased noise that can be tolerated while
maintaining the designed BER (bit error rate).
Downstream/Upstream Max
SNR Margin
Configure the maximum amount of increased noise that can be tolerated while
maintaining the designed BER (bit error rate).
Downstream/Upstream Max
InterLeave Delay
Adjust DS/US maximum interleave download delay settings (in ms) allowed Max
from 0 to 62 ms.
Trellis Coding
Enable or disable Trellis coding.
RFI Mode
Enable or disable G.993.2 RFI cancellation.
BitSwap
Enable or disable BitSwap.
VDSL2 Profile
Select VDSL2 Profile ??????????
PSD Mask Selection
Environmental conditions, especially radio interference can cause significant
problems in any or all bands. These masks will limit crosstalk between VDSL lines
on the switch. Choosing one of these masks will filter noise from other VDSL lines
on the switch.
Limited PSD Mask
DS Reduced PSD Mode
US Reduced PSD Mode
Upstream/Downstream
Virtual Noise State
SRA Mode
SOS Mode
Robust EOC Ratte
UPBO
Users may enable or disable the UPBo function using the corresponding radio
buttons. Upstream Power Back Off (UPBO) is used to avoid lowering the
performance in long loops due to strong FEXT which was generated by a short loop.
The result of enabling this feature should result in higher upstream bit rates.
DPBO
US0 Band
When the US0 Band is enabled, VDSL lines can be connected over longer
distances.
Click on the
Apply
button to set these configurations in the memory of the switch.
