Procedure
Step 1 Set up network environment according to the preceding diagrams for service acceptance tests.
NOTE
Ensure clock synchronization for the test. It is recommended that the tester use the internal free-run clock, the
OLT trace the clock of the tester, and the ONU trace the clock of the OLT.
Step 2 Use the E1 line tester to send packets for the test.
The test duration must be 12 hours or longer. There should be no alarms on the tester and the
bit error rate must be less than 1E-9.

Follow-up Procedure
