Output 110
The outgoing data bus (OD[7:0]) carries
SONET/SDH frame data in byte serial format.
108
106
104
97
In outgoing byte interface mode (OBMODE set
high), OD[7] is the most significant bit,
corresponding to bit 1 of each serial word, the
bit transmitted first. OD[0] is the least significant
bit, corresponding to bit 8 of each serial word,
the last bit transmitted. In floating mode,
OD[7:0] contains valid data only for bytes in the
VC3 or VC4 virtual container(s), or the STS-1
synchronous payload envelopes. Its contents
should be ignored for bytes in the transport
overhead. In locked mode, OD[7:0] is set to all-
zeros at transport overhead bytes, except for a
valid pointer with offset 522 at H1, H2 bytes.
The OD[7:0] bus is updated on the rising edge
of SCLK.

In outgoing nibble interface mode (OBMODE set
low), OD[3] is the most significant bit of each
nibble, corresponding to bit 1 or bit 5 of each
serial word, the bit transmitted first or fifth,
respectively. OD[0] is the least significant bit,
corresponding to bit 4 or bit 8 of each serial
word, the fourth or last bit transmitted,
respectively. OD[7:4] are set low. In floating
mode, OD[3:0] contains valid data only for bytes
in the VC3 or VC4 virtual container(s), or the
STS-1 synchronous payload envelopes. Its
contents should be ignored for bytes in the
transport overhead. In locked mode, OD[3:0] is
set to all-zeros at transport overhead bytes,
except for a valid pointer with offset 522 at H1,
H2 bytes. The OD[7:0] bus is updated on the
rising edge of NSCLK.
