TFIFOINV:

The TFIFOINV bit selects the active polarity of the TFIFOFB/TFIFOEB signal.

The default configuration selects TFIFOFB/TFIFOEB to be active low. When

TFIFOINV is set to logic one, the TFIFOFB/TFIFOEB signal becomes active

high. If TXPHYBP is set to logic one, TFIFOINV is not used and should be set to

logic zero.

AUTOPRDI

The AUTOPRDI bit determines whether STS path Remote Defect Indication

(RDI) is sent immediately upon detection of an incoming alarm. When

AUTOPRDI is set to logic one, STS path RDI is inserted immediately upon

declaration of loss of signal (LOS), loss of frame (LOF), line AIS, loss of pointer

(LOP), or STS path AIS.

AUTOLRDI

The AUTOLRDI bit determines whether the line Remote Defect Indication (RDI)

is sent immediately upon detection of an incoming alarm. When AUTOLRDI is

set to logic one, line RDI is inserted immediately upon declaration of loss of

signal (LOS), loss of frame (LOF) or line AIS.

AUTOFEBE

The AUTOFEBE bit determines whether line and path far end block errors are

sent upon detection of an incoming line and path BIP error events. When

AUTOFEBE is set to logic one, one line or path FEBE is inserted for each line or

path BIP error event. When AUTOFEBE is set to logic zero, incoming line or path

BIP error events do not generate FEBE events.

RATE[1:0]:

The RATE[1:0] bits select the operation rate of the LASAR-155. The default

configuration selects STS-3c (STM-1) rate operation. The LASAR-155 will not

operate correctly if a Reserved mode is selected.
