Communication Ports
The RS930L can be equipped with various types of communication ports to enhance its abilities and
performance. To determine which ports are equipped on the device, refer to the factory data file available through
ROS . For more information on how to access the factory data file, refer to the

Section 3.1
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
.
