4.1.2 Wiring
VDSL typically operates over 2-wire CAT-3 wiring; however, other categorized or uncategorized
twisted-pair wiring will work although the performance will vary depending on the distance and
cable characteristics. It is important that the wiring used does not have any open leads (also known
as bridged taps or drop-lines) along its length because this will impact performance by degrading
the signal.
4.1.3 Configuration & Setup
1. Log into the RuggedSwitch Operating System.
2. Highlight Ethernet Ports and press Enter.
3. Highlight Configure/View EoVDSL Parameters and press Enter. This will take you to the
EoVDSL Parameters screen. Press Enter again.
4. Highlight Mode and press Enter.
5. Either press the Up or Down arrow to select either Master or Slave. Press Enter.
6. Press Control and A together to apply the changes.
Once configured as master and slave and connected together, the units will then attempt to
achieve the maximum speed based on the line length and conditions. The unit’s link LED may flash
on and off several times before settling on a final link speed and declaring the port up. Please see
the Rugged Operating System (ROS) Software User Guide for detailed software configuration
options.
