OSCM and OSC-CSM Cards Optical Channel Alarm Thresholds Settings
Description
(Display only) Displays the port number. —
Shows the optical power failure low
threshold for the port. The threshold is
calculated automatically when you run
ANS. If the VOA Mode is Constant
Attenuation, you can manually change
the threshold. The value must be within
the optical power range that is specified
for the card. (See Appendix B,
"Hardware Specifications.")
If VOA Mode is Constant Power, you
cannot change the threshold manually
because it is based on the Power setpoint
(Optics Thresholds tab). To change the
threshold, you must change the VOA
Power Calib value. This adjusts the
Power setpoint. The threshold is
automatically set to a value that is 5 dB
higher than the Power setpoint.
Shows the power degrade high threshold.
This power value applies to the
corresponding port and is automatically
calculated when ANS is run.
This threshold applies to a port that is
associated to a VOA (OSC-VOA). In
Constant Power mode, the port is always
active and the threshold is automatically
linked to the Power Setpoint (VOA
Power Ref + VOA Power Calib). To
change the threshold, change the Power
Setpoint. The threshold will always be 2
dB higher than the Power Setpoint.
Shows the power degrade low threshold.
This power value applies to the
corresponding port and is automatically
calculated when ANS is run.
This threshold applies to a port associated
to a VOA (OSC-VOA) always active in
Constant Power mode.
In this case, the threshold is automatically
linked to the Power Setpoint (VOA
Power Ref + VOA Power Calib)
provisioned. Changing the setpoint will
result in changing the threshold (always
2 dB lower).
