ROW 1
DOUT[7:0] bus when OJ1EN is low. In this case the outgoing VC4 is locked with
respect to the outgoing transport envelope frame. This example illustrates the
case where the VC4 carries TUG3s that are all configured to carry TU3s. The
more general case where OJ1EN is high would be similar, except that the VC4
would be floating within the transport envelope frame.
Figure 7
Yet another example of the placement of tributaries assumed in AU4 mode is
illustrated in Figure 8. For simplicity, this figure shows the frame on the
DOUT[7:0] bus when OJ1EN is low. In this case the outgoing VC4 is 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 a complex case where the VC4
carries TUG3s and where TUG3 #1 carries a TU3, TUG3 #2 carries TUG2s that
are all configured to carry TU11s, and TUG3 #3 carries TUG2s that are all
configured to carry TU12s. The more general case where OJ1EN is high would
be similar, except that the VC4 would be floating within the transport envelope
frame.
