PRBS Test

In this user interface, you can perform an in-service PRBS test for a board of WDM equipment. The test result is displayed in the coordinates pane.

In the NE Explorer, click a board and choose Configuration > PRBS Test from the Function Tree.

NOTE:

The PRBS test will interrupt the service.
A PRBS test is used only in deployment. After the deployment, set PRBS Test Status to Disabled.

Button	Description
Query	Queries PRBS test results and displays the results in the graph. The query operation provides only the latest summary result of the test and refreshes the diagram accordingly. The intermediate results will be lost. When the results of all PRBS test periods are Normal, the results are displayed in the color of Normal. When the results of certain PRBS test periods are Invalid, the results are displayed in the color of Invalid. When the PRBS test results of all periods are BitError and the value of Total PRBS is equal to or greater than 4294967295, the results are displayed in the color of Invalid. If the value of Total PRBS is smaller than 4294967295, the results are displayed in the color of BitError.
Start to Test	Start the PRBS test.
Stop to Test	Stop the PRBS test.

Item	Description
Clear Result	Clears the PBRS test result.

Field	Value	Description
Port	Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)	Displays the port.
Duration	1 to 255	Sets the test duration.
Measured in Time	s, 10min, h	Sets the test time unit. NOTE: Currently, the following PRBS tests are available: short-time test, long-time test, and extra-long-time test. In the case of the short-time test, the test period is one second. The system reports the PRBS test result once every second. In the case of the long-time test, the test period is ten minutes. The system reports the PRBS test result once every minute. In the case of the extra-long-time test, the test period is one hour. The system reports the PRBS test result once every minute.
Start Time	Year-Month-Date Hour:Minute: Second	Specifies the test start time.
Progress	For example: 5%	Specifies the test progress.
Total PRBS	For example: 0	Specifies the total number of bit errors during PRBS test.
Accumulating Mode	Checked, Unchecked	Checks this check box to enable the accumulating display. NOTE: In a cumulative mode, the bit error value in the n second is the sum of the bit errors in the previous n seconds.
