BERT

The Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected HSU port. The patterns that can be selected are off, mark (1111), space (0000),
1:1 (1010 alternating), 1:7 (0100-0000), 511 (511 test pattern), qrss (quasi-random signal
source), and 2047 (2047 test pattern).
