ONT sends the following for the 40GE/100GE PCS invalid alignment marker insertion: M0 = 0xAA M1 = 0x77 M2 = 0xA7
Note that the full alignment marker is composed of the above values, a valid BIP3, M4 through M6 (bit-wise inversion of inverse of M0 through M2) and BIP7 (bit-wise inversion of BIP3). Therefore, other than M0 through M2 having invalid values, the alignment marker is otherwise valid.
M0 = 0xAA
M1 = 0x77
M2 = 0xA7
