20 EoVDSL Ports
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 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).
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 ROS 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 port is set to be a Master or Slave. On devices with Long-Reach
EoVDSL ports, the Master LED will be on all the time if the device is set to be the Master, or off if the device is set
to be the Slave.
