VDSL Setting (Port Common Setting)
VDSL Low Speed
Re-setting
Allows you to set the communication mode of the 10/100BASE
port and check the setting. Set the communication speed and
flow control.
If they are set, disconnect and reconnect a 10/100BASE cable.
٨
Communication speed
Initially set to Auto (auto negotiation). Make the
communication speed setting consistent with the network
apparatus to be connected. If inconsistent, the Equipment
may not work properly.
٨
Flow control
This function is to prevent a packet loss when the received
data processing speed exceeds the transmitted data speed or
due to buffer overflow resulting from concentration of received
packets. An initial value is no flow control.
Allows you to check the 10/100BASE setting.
Re-sets the VDSL circuit transmission speed at set time for all the ports of the
VDSL circuit. Use this when the transmission speed slows down due to the
installation environment (when fixed at the minimum speed of 1.2/1.3 Mbps).

VDSL Setting (Setting by Ports)
Selection of VDSL Port
VDSL Speed Setting
Set Valid/Invalid for all the ports of the VDSL circuit. An initial
value is
㨬
Valid
㨭
for all the VDSL ports. Set
㨬
Invalid
㨭
for those not
used. Otherwise, the transmission speed of the VDSL circuit
may slow down due to a cross talk between the cables.
Sets the transmission speed of the VDSL circuit. Automatic
control is provided so that the optimum transmission speed will be
obtained between the set transmission speed and the minimum
speed in the installation environment.
The transmission speed may differ depending on the installation
environment. The following lists the reference values when all the
VDSL circuit ports are wired to the identical UTP cable (setting
upon shipment from the factory).
̪
When using the ADSL circuit in combination with the Equipment,
set to
ޟ
43/25 Mbps (ADSL Friendly).
ޠ
An interference of the VDSL and ADSL signals may be reduced.

S/N Ratio Margin Setting
Used when communication over the VDSL circuit is unstable. If
communication over the VDSL circuit is unstable, increase a S/N
ratio margin. The transmission speed slows down, but
communication may be stabilized.
