PRODUCTION DATA
The frames formed by the transport layer are packed into 8-octet long blocks (64 bits). This 64-bit block is scrambled and then a 2-bit sync header (SH) is appended to form a 66-bit transmission block. The sync header is used for block synchronization by marking the end of a block as well as allowing for cyclic redundancy checking (CRC), forward error correction (FEC) or a command channel. The structure of a block is given in Table 6-18 where SH represents the appended 2-bit sync header.
SH | OCTET0 | OCTET1 | OCTET2 | OCTET3 | OCTET4 | OCTET5 | OCTET6 | OCTET7 |
