8.10. EMBEDDED CONTROL SYMBOLS
Control symbols can be embedded anywhere in a packet in the same fashion as pacing idle control symbols, as long as all delineation and alignment rules are followed (Figures 8.13, 8.14). As with the pacing idle control symbols, the embedded control symbols are not included in the CRC value calculation for the packet.

A special error case exists when a corrupt embedded control symbol is detected. In this case a packet-not-accepted control symbol is generated and the embedding packet is discarded.
