Can I use the built-in Bit Error Rate Test (BERT) set to test the line or DTE side equipment?
Yes and No. The BERT is designed to transmit and receive to the modem side. It is however possible to use two other schemes in certain cases. First is to use the BERT at the far end modem to generate and/or sink the BERT test pattern. Second, the local modem can be set into an IF loop-back mode to use just one side of the BERT at a time. For example a test pattern can be sent from the receive output by enabling the transmit BERT only while setting the IF loop-back mode. See Maintenance Section 4.1.2 for information on using the built-in BERT.
