BERT Configuration

The following options apply to any of the tests involving BERT testing.

Pattern

Select the desired test pattern for the BERT test (see Figure 6-10). The internal test pattern generator can be configured for the following types of test patterns:

•All Zeros

•All ones

•2^15-1

•2^23-1

The test pattern is used to independently test the operation of the framing circuitry and the network interface of the T3SU 300. Instead of using data from the host, this test uses data generated by the T3SU 300’s internal test pattern generator and detector.
