• 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 DSLAMrelated 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. 67

•
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.
