Enable rates greater than 5696 kbps
Leave this box unchecked if you know that the distance of the line does not allow a connection at higher data
rates. Thus the range of tested rates will be narrower and the result will be more accurate or the connection
setup time faster.
Minimum connection time before allowing a fast reconnect
If the connection has been stable for some time and if a disconnection occurs for example because of a brief
disturbance, it is likely that the conditions of the line have not changed. The XS can attempt the direct
reconnection at the same rate as before which can significantly reduce the duration of unavailability of the
link.
Possible values :
0 to 86400 s (0 means unused)
Fast reconnect attempt timeout
When a disconnection occurs and the XS again detects the equipment at the other end before this Timeout
then it can attempt the direct reconnection at the same rate as before which significantly reduces the link
downtime.
Possible values :
0 to 120 s (0 means unused)
Advanced settings :
Annex
Possible values :
Annex A or Annex B
Default value :
Annex A
PAM constellation
The PAM constellation defines the modulation used.
Possible values :
Auto, PAM16, PAM32
Default value :
Auto
Capacity list
The capacity list exchanged between the switches can be performed in an old way to interoperate with legacy
switches generation (XSLAN- family).
Possible values :
Auto, Old style, new style
Default value :
Auto
Power-back off mode
Reduces the transmitting power when the lines are short to least disturb the surrounding lines (crosstalk).
Possible values :
Normal, Forced
Default value :
Normal
Use EPL to calculate Power back-off
TBD
Enable extended rates
Check this checkbox to activate the extended data rate for transmitting up to 15 Mb/s when the line is less
than 1 Km.
Extended constellation
The PAM constellation defines the modulation used.
Possible values :
Auto, PAM 4, PAM8, PAM16, PAM32, PAM64, PAM128
Default value :
Auto
