Hi HPB,

As I understand it, you have some inquiries related to the Enh PCS acting as PCS Direct. For your information, as I look at the Enh PCS path block diagram in the user guide, it seems like you are not able to bypass all the internal blocks. For example, the TX gearbox, RX gearbox and block synchronizer will always be there. Therefore, in term of architecture, we cannot say it will become same as PCS direct. However, since most of the blocks can be bypassed in Enh PCS, you can perform some simulation to check if after bypassing these blocks, it can work as per your target requirement.

Please let me know if there is any concern. Thank you.

Best regards,
