Table 11-22 32WSS Optical Channel Alarm Threshold Settings
Parameter Description Options
Port (Display only) Displays the port number.
For each optical channel (wavelength), two
logical ports are associated. Only one port
can be active at a time, depending on the
port’s operating mode. The operating mode,
provisioned on the card view Maintenance
tab, is either Add Drop or Pass-Through.
Ports 1 through 32 (RX) are associated to
optical channels configured as Add Drop
channels. Ports 33 through 64 (PT) are
associated to optical channels configured as
Pass-Through channels.

Power Failure
Low (dBm)
Shows the power failure 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.
The threshold is automatically linked to the
Power Setpoint (VOA Power Ref + VOA
Power Calib) provisioned. Changing the
setpoint results in changing the threshold
(always 5 dB lower).
The threshold is calculated automatically
when you run ANS. 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.”)
Numeric. Double-click the parameter,
enter a value, and press Enter.
Power Degrade
High (dBm)
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 associated to
a VOA (OSC-VOA) always active in
Constant Power mode.
The threshold is automatically linked to the
Power Setpoint (VOA Power Ref + VOA
Power Calib) provisioned. Changing the
setpoint results in changing the threshold
(always 3 dB higher).
