When written to 1, automatic generation of downstream AIS-L is
enabled. When written to 0, automatic generation is disabled.
When written to 1, automatic generation of downstream AIS-P for
STS path 1 is enabled. When written to 0, automatic generation is
disabled.
When written to 1, automatic generation of downstream AIS-P for
STS path 2 is enabled. When written to 0, automatic generation is
disabled.
When written to 1, automatic generation of downstream AIS-P for
STS path 3 is enabled. When written to 0, automatic generation is
disabled.
When written to 1, the receive frame scrambler is disabled.
When written to 1, the H1, H2, and H4 bytes in the first STS-1 are
replicated into the second and third STS-1 H1, H2, and H4
positions. When written to 0, the H1, H2, and H4 bytes in the
second and third STS-1s are passed as received.
When written to 1, downstream AIS-P is also generated on
reception of PLM-P or Uneq-P. This bit controls all three STS-1s in
this STS-3. When written to 0, AIS-P is generated only on
reception of LOP-P.
When written to 1, automatic generation of downstream AIS-P for
STS path 4 is enabled. When written to 0, automatic generation is
disabled.
