4.2.2
Configuration and Setup
If the RUGGEDCOM RSL910 and another device both have Universal EoVDSL ports,
configure one device to be the Master and the other the Slave.
Once configured and connected together, each device will attempt to achieve the
maximum speed based on the line length and conditions. The RUGGEDCOM RSL910's
Link/Act LED may flash on and off several times before setting on a final link speed
and declaring the port up.
For more information about configuring the RUGGEDCOM RSL910, refer to the
"RUGGEDCOM ROS Configuration Manual" for the RSL910.

EoVDSL Performance
The following describes the behavior and performance characteristics of EoVDSL.
Bit Rates
The EoVDSL terminals can be configured to use a specific bit rate for downstream
and upstream communications (e.g. 140/140 Mbps, 85/85 Mbps, etc.), or to
determine the optimal bit rate automatically based on the current line conditions.
When a specific bit rate is selected, the device will only attempt to attain the selected
speed.
Signal Degradation
An EoVDSL terminal in Master mode can be configured to automatically scan the
available VDSL profiles for a more optimal link. The terminal can be configured to
initiate the scan when the link goes down to alert users to the lost connection.
Note
If the EoVDSL terminal is set to achieve a specific bit rate, the device will only select
links that can achieve the selected bit rate.
Note
Assuming the distance can support the speed setting, the time to establish a link is
typically 120 seconds.
Universal EoVDSL Performance Characteristics
On No. 24 AWG Polyethylene Insulated Cable (PIC) twisted-pair wiring, the following
performance is typical with Universal EoVDSL:
