Dear All, 
    802.3bs D1.1 clause 119.2.4.4 Figure 119-6 show us AM transmit on 16 PCS lanes,but Alignment marker insert cycle is 163840*257bit,after Pre-FEC Distribution and symbol distribution,What is the AM format  mapping to PCS lanes? 
    after FEC encode RS(544,514), AM cycle is 163840 * 257 * 544 / 514 = 163840 * 272 bit 
    How is clause 119.2.5.1 Alignment lock and deskew ?   
    looking forword your reply. 
Yours
