For those of us with wire still left in the ground

There is a box that can make it talk fast

EoVDSL

• Eo Ethernet over• V very high bit rate• DSL Digital Subscriber Line

Enhanced Rapid Spanning Tree Protocol (eRSTP™)

RuggedCom eRSTP allows the creation of fault-tolerant ring and mesh Ethernet networks that incorporate redundant links that are 'pruned' to prevent loops.

RJ11 Ethernet over VDSL Port

The unit contains one EoVDSL data port that allows connection to Category 3 (CAT-3) unshielded twisted-pair (UTP) cable with RJ11 male connectors. The figure below shows the RJ45 port pin-out and LEDs.

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.

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 35.00 150.6 2000 30.00 300.7 2300 25.00 450.8 3000 20.00 601.0 3300 15.00 751.3 4300 10.00 901.7 5600 5.00 1052.0 6600 2.50 1202.5 8200 1.00 135
