EoVDSL Ports
Ethernet over VDSL (EoVDSL) connections operate in pairs with one device
configured as the Master and the other as the Slave. In VDSL (Very-high-bit-rate
Digital Subscriber Line), the terms Central Office (CO) or Line Termination (LT) are
used interchangeably for the Master, and the terms Customer Premise Equipment
(CPE) or Network Termination (NT) are used interchangeably for the Slave. All
EoVDSL line configuration settings are modified on the Master and pushed to the
Slave. Data flowing from the Master to the Slave is designated downstream, while
data flowing from the Slave to the Master is designated upstream.
Siemens supports two types of EoVDSL:
•
•
Universal and Long-Reach EoVDSL ports are physically indistinguishable from each
other. However, the port type can be determined either from the order code or
through the RUGGEDCOM RS910L user interface.
EoVDSL ports can be connected using RJ11 male connectors.
IMPORTANT
Universal and Long-Reach EoVDSL ports (master or slave) must be connected to
EoVDSL ports (slave or master) of the same type. Connection between Universal
EoVDSL ports and Long-Reach EoVDSL ports is not supported. While master/slave
mode can be modified on Universal EoVDSL ports, the operating mode of all Long-
Reach EoVDSL ports is predetermined by hardware. As a result, master/slave mode
cannot be modified on Long-Reach EoVDSL ports.
LEDs
Each EoVDSL port has a Link/Act LED and a Master LED. On devices with Universal
EoVDSL ports, the Master LED can be toggled on or off depending on whether the

Universal EoVDSL
Universal EoVDSL ports are Master/Slave selectable and offer symmetric data
rates (upstream and downstream) up to 35 Mbps. They are best suited for higher
throughput connections spanning distances up to 2.5 km (1.6 mi).
Long-Reach EoVDSL
Long-Reach EoVDSL ports are fixed as either Master or Slave, but offer
asymmetric data rates (upstream and downstream) up to 40 Mbps. They are best
suited for lower throughput connections spanning distances up to 5 km (3.1 mi).
