BERT

Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER) on the selected SRU port. The patterns that can be selected are off, mark (all ones), space (all zeros), 1:1 (alternating 10101010), 1:7 (10000000), 511 (511 test pattern), and 2047 (2047 test pattern).

DIR

The Direction (DIR) setting allows you to specify where the BERT test signal should be directed. The first option is net (network) which means that the test signal will be transmitted through the system toward the Wide Area Network (WAN). The user option means that the signal will be directed toward the attached DTE device over the RS-232 interface.
