Parameters
BERT Options
Stop function
Allows you to specify when the measurement ends. Select the relevant
option from the drop-down menu:
Manual stop: Stops the measurement immediately when you touch the
Stop button.
Stop at: Stops the measurement at the time specified in the Stop at
field on the right.
Duration: Performs the measurement for the duration of time specified
on the right.
Memory allocation
Allows you to specify how the measurement will be stored in the Network
Master's memory. Select the relevant option from the drop-down menu:
Use all storage: When Network Master's memory becames full of
measured data, the whole measurement is stopped.
Continuous: When Network Master's memory becames full of
measured data, the oldest records in that memory will be overwritten.
The Network Master's memory size (the file size of measurement results) is
64 Mbytes per one port.
Estimate of test duration
Contains an estimation of the time (in days, hours, minutes and seconds)
before the whole memory will be filled out by the test. During an ongoing
measurement, the estimate will be recalculated periodically.
If the FC signal is carried by OTN, the following parameters related to OTN
are available:
OTN
G.8201, M.2401 (M.2110)
Time period
15 minutes, 1 hour, 2 hours, 24 hours, 7 days
Allocation
Touching the Setup button launches the dialog box. Refer to Performance
Parameters in "OTN Application" .
Count lost frames as pattern errors
Enabling this function means that if a frame is lost, all test pattern bits in the
frame are considered errored and will be included in the pattern error
counter.
Include addresses in frame filter on receiver
The receiver uses a filter to determine which frames should be counted in
the results. When this function is enabled, the following fields are required to
match:
Source ID
Destination ID
R_CTL (=0x00, Uncategorized FC-4)
Type (=0xE0, vender unique type)
When this function is not enabled, the following fields are required to match:
Most significant byte of R_CTL should be equal to 0. (FC-4 data)
Only show BER Alarms when measuring
BER alarms in Interface status dialog box is enabled only when the
measurement is running. This function allows to avoid the BER alarms
occurrence when no data is input.
