Tx Power Control (VDSL):
It allows you to configure the Tx
Power for VDSL to improve the downstream speed. A low
Tx Power value increases the downstream speed but affects
the upstream speed, and vice versa.
•
Rx AGC GAIN Adjustment (VDSL):
Allows you to configure
Rx AGC GAIN (Auto Gain Control) for your VDSL line. You can
set this item to any of these modes:
•
Stable:
Select this mode to get a stable VDSL connection.
•
High Performance:
Select this mode to improve the current
downstream speed.
•
Default:
Select this mode for your xDSL modem router to
automatically assign the suitable mode for your VDSL line.
•
UPBO/Upstream Power Back Off (VDSL):
This item
allows you to enable or disable UPBO (Upstream Power
Back Off) for VDSL. DSLAM (Digital Subscriber Line Access
Multiplexer) uses UPBO to reduce the Tx Power of your xDSL
modem router. In some cases, UPBO control from DSLAM
may lead to sync issue, such as Tx Power is too low to sync
at minimum rate. Disable this item to prevent any DSLAM-
related sync issues.
•
Seamless Rate Adaptation:
This item allows you to enable
SRA (Seamless Rate Adaptation) for consistent data transfer
rates and preventing dropped connections. You may
disable this item when your connection is very stable and
there is a decrease in download or upload speed.
•
Bitswap:
This item allows you to enable Bitswap, which
adjusts bits allocated for bins/channels. Busy or congested
bins/channels are assigned fewer bits while available
channels are allocated more bits to handle.
•
VDSL Profile:
This item allows you to configure the VDSL
Profile. The default value is 30a multi mode.
NOTE:
For some ISPs with non-standard 30a multi mode VDSL DSLAM
sync setting, such as for ISP services in Germany, set the VDSL Profile to
17a multi mode to sync up the VDSL line.
