4.2.2 Configuration And Setup; Eovdsl Performance - Siemens SIMATIC NET RUGGEDCOM RS930L Installation Manual

4.2.2 Configuration and Setup
If the RUGGEDCOM RS930L and another device both have Universal EoVDSL ports,
configure one device to be the Master and the other the Slave. If both devices have a
Long-Reach EoVDSL port, no Master/Slave configuration is necessary, since the ports
will already be fixed as Master or Slave.
Once configured and connected together, each device will attempt to achieve the
maximum speed based on the line length and conditions. The RUGGEDCOM RS930L's
Link/Act LED may flash on and off several times before setting on a final link speed
and declaring the port up.

RUGGEDCOM RS930L User Guide for the .

EoVDSL Performance

The following describes the behavior and performance characteristics of EoVDSL.
EoVDSL Modes
The EoVDSL ports can be configured to operate in one of two modes:
•
•
If the line conditions degrade (reducing the SNR or Signal to Noise Ratio), but the de-
vice is able to maintain the link, an alarm will be triggered to notify the user of the
reduced SNR. By configuring the Rescan Mode parameter in RUGGEDCOM RS930L,
the user can control at which point the scan process will be restarted when the line
conditions degrade. If Link only is selected, the device will restart the scan process
if the line conditions degrade, such that the device is unable to maintain the current
link. If Link or SNR is selected, the device will restart the scan process if either the
SNR has dropped below a pre-defined acceptable level or when the device is unable
to maintain the current link, or whichever comes first.
Note
If the Mode parameter is set to Manual Mode, the restart of the scan process will on-
ly attempt to attain the set speed in manual mode.
For information about configuring EoVDSL, refer to the RUGGEDCOM RS930L User
Guide for the RUGGEDCOM RS930L .

Installation Manual, 02/2020, C79000-G8976-1034-06
Auto Mode (default)
In Auto Mode, the device will step through the different speeds and automatical-
ly select the best bit-rate based on the current line conditions.
Manual Mode
In Manual Mode, the user can select one of the speed settings and the device will
only attempt to attain the set speed.
