12.2 STS-1 Mode
12.3 AU3 Mode
ROW 1
An example of the placement of tributaries assumed in STS-1 mode is illustrated
in Figure 4. For simplicity, this figure shows the frame on the DOUT[7:0] bus
when OJ1EN is low. In this case the outgoing STS-1 SPEs are locked with
respect to the outgoing transport envelope frame. This particular example
assumes a snapshot of the first frame of the tributary multiframe when the V1
bytes are present. This example illustrates a VT structured STS-1 SPE where all
VT groups are configured to carry VT1.5s. The more general case where OJ1EN
is high would be similar, except that the STS-1 SPE would be floating within the
transport envelope frame.
Figure 4
An example of the placement of tributaries assumed in AU3 mode is illustrated in
Figure 5. For simplicity, this figure shows the frame on the DOUT[7:0] bus when
OJ1EN is low. In this case the outgoing VC3s are locked with respect to the
outgoing transport envelope frame. This particular example assumes a snapshot
of the last frame of the tributary multiframe when the V4 bytes are present. This
example illustrates the case where the VC3s carry TUG2s and all TUG2s are
configured to carry TU12s. The more general case where OJ1EN is high would
be similar, except that the VC3s would be floating within the transport envelope
frame.
