3.1.2 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.

3.1.3 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.

3.1.4 Performance

On 24 American Wire Gauge (AWG) Polyethylene Insulated Cable (PIC) twisted-pair the following performance is typical:

Distance	Distance	Downstream/Upstream	Time to Achieve Port Up
[km]	[feet]	[Mbps]	[Seconds]
0.5	1600	35.00	15
0.6	2000	30.00	30
0.7	2300	25.00	45
0.8	3000	20.00	60
1.0	3300	15.00	75
1.3	4300	10.00	90
1.7	5600	5.00	105
2.0	6600	2.50	120
2.5	8200	1.00	135
