EoVDSL Ports
Ethernet over VDSL (EoVDSL) ports 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. The Master device dictates the line configuration
settings to the Slave so all EoVDSL configuration is done on the Master. Data flowing from the Master to the
Slave is designated
downstream
while data flowing from the Slave to the Master is designated
upstream
.
Siemens offers two flavors of VDSL: Universal EoVDSL and Long-Reach EoVDSL. Universal EoVDSL ports are
Master/Slave selectable and offer symmetric data rates up to 35 Mbps with distances up to 2.5 km (1.6 mi). Long-
Reach EoVDSL ports are fixed as either Master or Slave but offer asymmetric data rates up to 40 Mbps with
distances up to 5 km (3.1 mi).
The 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 ROS.
EoVDSL ports can be connected using RJ11 male connectors. 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.
