EoVDSL Ports
Ethernet over VDSL (EoVDSL) connections operate in pairs with one device config-
ured as the Master and the other as the Slave. In VDSL (Very-high-bit-rate Digital Sub-
scriber Line), the terms Central Office (CO) or Line Termination (LT) are used inter-
changeably for the Master, and the terms Customer Premise Equipment (CPE) or Net-
work Termination (NT) are used interchangeably for the Slave. All EoVDSL line con-
figuration 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 asymmet-
ric 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 RS930L 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 Univer-
sal 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.
