Passing the Status Bytes
The 9216-OE-DM replaces Channel Status Bytes according to Table 5.2 or passes Status Bytes
through from input to output. In order for the Channel Status Bytes on the incoming embedded stream
to be re-embedded, the outgoing Data Word Length must match the specified word length in the
Channel Status bits.
