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.

Navigation Path

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

NOTICE:

The PRBS test will interrupt the service.

Parameters

Field	Value	Description
Port	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: slot number-board name-port number(port name)	Displays the port.
Start Time	yyyy-mm-dd hh:mm:ss	Displays the start time of the test. For example: 2004-12-6 15:40:12.
Elapsed Time (min)	Minutes Default: 0	Displays the elapsed time of the test.
Progress	Percentage For example: 0%	Displays the progress of the test.
State	INITIAL, RUNNING, STOPPED, Abnormal Stopped Default: INITIAL	INITIAL: For the NM, this port has never been tested. RUNNING: The test is performing. STOPPED: The test has been stopped. Abnormal Stopped: NM detect the test has been abnormally stopped.
Test Mode	SPLTE, SPLTF Default: SPLTE	Indicates the requested test mode. The expected entries for this parameter are listed below: SPLTE: Split both the A and B paths (the direction of A path is from equipment test access point to facility test access point, and the direction of B path opposite to that of A) and connect a signal presence detector to the line incoming from the E direction (equipment test access point direction) and a test signal to the line outgoing in the E direction. The line outgoing in the F direction (facility test access point direction) shall have an AIS signal connected, and the line incoming from the F direction shall be terminated by the nominal characteristic impedance of the line. SPLTF: Split both the A and B paths and connect a signal presence detector to the line incoming from the F direction and a test signal to the line outgoing in the F direction. The line outgoing in the E direction shall have an AIS signal connected, and the line incoming from the E direction shall be terminated by the nominal characteristic impedance of the line.
Test Duration (min)	To enter: 0 to 9999 minutes To enter: long-term, 1 minute, 10 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours Default is 0	Displays the time in minutes that bit sequence test sustains. If the value is 0, long-term PRBS test is to be performed.
Report Interval (s)	1 second, 2 seconds, 6 seconds, 30 seconds, 1 minute, 10 minutes, 30 minutes, 1 hour Default: 2s	Reports interval in seconds. If the value is 0, the PRBS test will be reported only once when the test is finished.
Time	yyyy-mm-dd hh:mm:ss	Displays the report time of the test. For example: 2004-12-6 15:40:12
Errored seconds count based on LSS	0 to 4,294,967,295	Errored seconds count based on LSS (Loss of sequence synchronization) detected, if the maximum count reached, a literal "OC" is added follow it.
Elapsed Time		Displays the elapsed time.
Total Bits Errors	0 to 4,294,967,295	Total bit error count (32 bit counter), if the maximum count reached, a literal "OC" is added follow it.
Error Count		Displays the error count.
Current Status		Displays the current status.
