BERT
The Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER)
on the selected BRI port. Depending upon whether the test is on B-channels or D-channels,
the patterns can be sent as either raw data or as HDLC packets containing the patterns. The
BERT signal can only be sent on one port at a time. There are no user options available. The
user selection is always n/a.
DIR
The Direction (DIR) field allows you to select the direction of the test. There are no user
options available. The user selection is always n/a.
CHAN
The Channel (CHAN) field allows you to select which side of the line the BER pattern will be
sent. There are no user options available. The user selection is always n/a.
SYNC
The Synchronization (SYNC) field shows if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test equipment.
Since this is an information-only field, there are no user-selectable parameters. You will see
either yes or no in this field.
BE
The Bit Error field (BE) shows the total number of bit errors logged. Since this is an
information-only field, there are no user-selectable parameters.
