. If the change affects traffic, a warning message displays. Click
Yes
to complete the
change.
VOA Mode
(Display only) Displays the active VOA
working mode.
•
Constant Power
•
Constant Attenuation
VOA Power
Reference
(Display only) Shows the value of the optical
power setpoint that must be reached on the path
where a VOA is present, when VOA Mode is set
to Constant Power. This value is the desired
per-channel optical power. This parameter can
only be modified by ANS.
Numeric value (dB)
VOA Power
Calibration
Allows you to modify the VOA power value
when VOA Mode is Constant Power.
Double-click the parameter, enter a value, and press
Enter
.
•
Numeric value (dB)
•
–37 dB to –2 dB
VOA
Attenuation
Reference
(Display only) Shows the attenuation value of
the VOA when the VOA Mode is Constant
Attenuation. This parameter can only be
modified by ANS.
Numeric value (dB)
VOA
Attenuation
Calibration
Allows you to modify the VOA attenuation
value when VOA Mode is Constant Attenuation.
Double-click the parameter, enter a value, and press
Enter
.
•
Numeric value (dB)
•
–30 dB to +30 dB
Actual
Wavelength
(Display only) Displays the actual wavelength
utilized by the channel.
•
Actual measured value (nm)
•
UNKNOWN
Expected
Wavelength
(Display only) Displays the expected
wavelength assigned for the channel.
•
Value (nm) from the ITU-T grid specification
•
UNKNOWN
Power ADD
(Display only) Displays a measurement of the
optical power coming in on the ADD RX port.
This is the power transmitted by the TX laser of
the TXP or MXP card that is connected to the
32WSS.
The measurement is performed by a photodiode
before the selector and the VOA. The
photodiode validates the power level of the
incoming wavelength power.
Numeric value (dB)
Path Value
(Display only) Displays Path value.
•
Standby
AINS Soak
(Display only) Sets the automatic in-service
soak period.
•
Duration of valid input signal, in hh.mm format, after
which the card becomes in service (IS) automatically
•
0 to 48 hours, 15-minute increments
