Payload BERT
The Payload BERT is useful in a point-to-point environment. The
Centum Series units at both ends of the circuit must be placed in a
Payload BERT condition with the same BER pattern.
SELECT as required to choose the desired Bit Error Rate pattern of 511,
2 of 16, or All Ones.
If the BER pattern was changed in the previous step, the BERT must be
turned OFF and back ON again to establish the new pattern.
If the CSU portions of the Centum Series unit and the T1 link are all
functioning properly, the Seconds/Test at both units will increment while
the Errored Seconds at both units will remain at
∅∅∅∅∅
.
WHEN TESTING IS COMPLETED, BE SURE TO TURN BOTH BERT
TESTS “OFF”.
