Invert Pattern

If set to ENABLE, the T3SU 300 inverts the transmitted and received BERT test pattern. This allows the unit to be compatible with test equipment which generates inverted BERT patterns.

BERT Information Fields

The following five fields provide information about the most recently issued BERT test. These fields appear in the main DIAGNOSTICS menu (shown in Figure 6-1).

Port

Displays which port is transmitting and receiving the BERT pattern.

Direction

Displays the direction in which the BERT pattern is being sent.

State

Displays either SYNC or NO SYNC to indicate whether or not the unit is in sync with the BERT pattern.
