When written to 0, the J1 byte contains 00h. When written to 1, the
Path Trace Message from the TXPTHBUF circular buffer is inserted
in the J1 byte.
When written to 0, the B3 byte contains the results of the path BIP
calculation. When written to 1, the B3 byte contains 00h.
When written to 1, path REI codes are automatically inserted in the
G1 byte upon reception of B3 errors. When written to 0, automatic
insertion is disabled.
When written to 0, Path AIS is not generated. When written to 1,
Path AIS alarm is generated.
This bit is mapped to Transmit RDI bit 5 in the G1 byte.
This bit is mapped to Transmit RDI bit 6 in the G1 byte.
This bit is mapped to Transmit RDI bit 7 in the G1 byte.
When written to 1, path RDI is automatically generated for at least
20 frames upon reception of LOS, LOF, LOP, AIS-L, AIS-P,
UNEQ-P, or PLM-P. When written to 0, path RDI is inserted from
bits 3–1 of this register.
