Register Description:
Register Address (LIUs 1–8):
Bit #
Name
Default
Note: This register enables the LIU1-LIU8 BERT. The BERT can only connect to one LIU at a time. The LIU1-LIU8 BERT operates
independently of the LIU9-LIU16 BERT.
Bits 7 to 5: Bit Error Rate Transceiver Select [2:0] (BTS[2:0]). These bits BTS[2:0] select the LIU that the BERT
applies to (see
Bit 0: Bit Error Rate Tester Enable (BERTE). When this bit is set and 2µs have past, the BERT will be enabled.
The BERT register set should be written and read to only after being enabled. The BERT is only active for one LIU
at a time selected by BTS[2:0]. If the BERT is enabled on the transmit (line) side, the BERT data will be
automatically B8ZS/HDB3 encoded before it is transmitted.
Register Address (LIUs 9–16):
Bit #
Name
Default
Note: This register enables the LIU9-LIU16 BERT. The BERT can only connect to one LIU at a time. The LIU9-LIU16 BERT operates
independently of the LIU1–LIU8 BERT.
Bits 7 to 5: Bit Error Rate Transceiver Select [2:0] (BTS[2:0]) These bits BTS[2:0] select the LIU that the BERT
applies too (see
Bit 0: Bit Error Rate Tester Enable (BERTE). When this bit is set and 2µs have past, the BERT will be enabled.
The BERT register set should be written and read to only after being enabled. The BERT is only active for one LIU
at a time selected by BTS[2:0]. If the BERT is enabled on the transmit (line) side, the BERT data will be
automatically B8ZS/HDB3 encoded before it is transmitted.
