Table 9-14. RXP CPU Header Descriptor – 3
The RXP Local Timestamp may be used by the CPU for OAM Timestamp purposes (not for clock recovery).
RXP CPU Packets are first stored in the SDRAM RXP CPU Queue. The CPU controls the transfer of each RXP
CPU packet to an internal staging RXP CPU FIFO that the CPU can read from. The FIFO holds one RXP CPU
Packet at a time. The RXP CPU Queue can hold up to 512 packets (each 2Kbyte slot of the RXP CPU Queue is
reserved for one packet).
