Payload Pattern
Selects the type of pattern that the unit expects to receive on
the incoming SDH signal.
Select one of the following patterns:
PRBS 9 , PRBS 9 Inv , PRBS 11 , PRBS 11 Inv , PRBS 15 ,
PRBS 15 Inv , PRBS 20 , PRBS 20 Inv , PRBS 23 , PRBS
23 Inv , PRBS 31 , PRBS 31 Inv , User Defined (32-bit value),
or Live .
If licensed for GFP , then GFP payload option is also
available.
When the actual pattern being received does not match
the expected payload pattern, then a pattern mismatch ( Pat
Sync ) alarm occurs.
Power Low
Threshold Sets the threshold for which the Power Low alarm occurs.
When the received optical power level (in dBm) is lower than
the power low threshold setting, the Power Low alarm will
occur. (MPM-10G card only)
The threshold value is entered using an on-screen keypad,
and can range from -10.0 dBm to -100.0 dBm in increments
of 0.1 dBm. The default value is -100.0 (Disabled).
For the MPM-100G and MPM-100AR cards, the Power
Low Threshold setting is supported on the MLD tab.
Out of Frequency
Threshold Sets the threshold for which the Frequency Wide alarm
occurs. When the received Line Frequency Offset (in ppm)
exceeds the set threshold setting, the Frequency Wide alarm
will occur.
The threshold value is entered using an on-screen keypad,
and can range from
0 ppm to +/- 300.0 ppm in increments of
0.1 ppm. The default value is 0 ppm (Disabled).
Trigger Out
Trigger Out is currently not supported.
