ORCA ORT8850 Data Sheet

violated a per channel alarm bit will be set indicating that this channel has exceeded the threshold, as well as a
FIFO out-of-sync alarm bit to indicate the channel is not longer in sync with the reset of the alignment group.
The incoming data can be considered as 4 STS-12 channels (A, B, C, and D) per quad. Thus we have STS-12
channels AA to AD from quad A of the STM and STS-12 channels BA to BD of quad B. The 8 channels of parallel
SONET data can be grouped into an alignment group by 2, by 4 or all 8 channels. As the serial data is run through
the backplane and SERDES the parallel data can be slightly varied. The alignment FIFO can absorb this difference
in the channels and create a byte aligned grouping.
These streams can be frame aligned in the following patterns. Streams can be aligned on a twin STS-12 basis as
shown in Figure 18. In STS-48 mode, all four STS-12s of each STM quad are aligned with each other (i.e. AA, AB,
AC, AD) as shown in Figure 19. Optionally in STS-48 mode all eight STS-12s (STMs A and B) can be aligned which
allows hitless switching since all streams will be byte aligned (Figure 20). Multiple ORT8850 devices can be aligned
with each other using a common system frame pulse to enable STS-192 or higher modes.
