EoVDSL Ports
The RUGGEDCOM RSL910 features a pluggable terminal block that supports up to two Universal EoVDSL
connections. Universal EoVDSL connections are Master/Slave selectable and offer symmetric data rates up to 140
Mbps (with a VDSL link data rate up to 100 Mbps) or distances up to 3 km (1.8 mi).
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 .
IMPORTANT!
Universal EoVDSL ports (master or slave) must be connected to other Universal EoVDSL ports (slave or
master). Connections between Universal EoVDSL and Long-Reach EoVDSL ports is not supported.
LEDs
Each set of EoVDSL terminals is associated with a set of Link/Act and Master LEDs. The Link/Act LED indicates
the state of the port, as well as the Signal-to-Noise Ratio (SNR). The Master LED indicates whether the device is a
Master or Slave.
