Maintenance The Element Maintenance screen (Figure 4-5) allows you to perform loop test
and/or BERT (Bit Error Rate Test) functions on the T1 circuit. You can activate
and clear loops and the bit error rate tester. BERT is performed by using on-board
test facilities. No other test equipment is needed.
