2. Set variable optical attenuator to obtain power level reading on optical power
meter as required from Table A.
3. Monitor the DS1 received signal with the DS1/DS3 Error Rate Test Set (ERTS)
for 30 minutes and ensure a bit error rate (BER) result of 10
–10
or better.
4. Did
OLIU
pass BER test?
If
YES
,
STOP. YOU HAVE COMPLETED THIS PROCEDURE
.
If
NO
, continue with
Step 5
.
5. Clean optical attenuators and connectors and repeat test. If test fails again,
replace
OLIU
.
