7.9 BERT
The BERT block can generate and detect the following patterns:
§ Maximal-length pseudorandom patterns up to 231 - 1
§ A repetitive pattern from 1 to 32 bits in length
§ Alternating (16-bit) words that alternate every 1 to 256 words
The BERT receiver has a 24-bit error counter and 32-bit bit counter to allow testing to proceed for long periods
without host processor intervention. It can generate interrupts on detecting a bit error, a change in synchronization,
or a counter overflow. The BERT can be selected to transmit and receive on the line side or the equipment side.
The synchronization algorithm works on a 32-bit block of data, not in a sliding window fashion.
The DS3/E3 formatter can be configured to transmit AIS when the BERT is not being used to test the far end, such
as when DLB is active or when BM[1:0] = 1X. When DLB is active, the BERT is used to test the inner workings of
the chip, and when BM[1:0] = 1X, the BERT is used to test devices connected on the equipment side (TDAT and
RDAT). In either case, BERT patterns are transmitted to the far end on TPOS and TNEG unless the DS3/E3
formatter is configured to transmit AIS by setting T3E3CR1:TAIS = 1.
