Bit 13: Receive FEAC Data Link Source (DLS) – When 0, the receive FEAC controller will be sourced from the N
bit. When 1, the receive FEAC controller will be sourced from the A bit.
Bit 12: Manual Downstream AIS Insertion (MDAISI) – When 0, manual downstream AIS insertion is disabled.
When 1, manual downstream AIS insertion is enabled.
Bit 11: Automatic Downstream AIS Disable (AAISD) – When 0, the presence of an LOS, OOF, or AIS condition
will cause downstream AIS to be inserted. When 1, the presence of an LOS, OOF, or AIS condition will not cause
downstream AIS to be inserted.
Bit 10: Error Count Control (ECC) – When 0, framing errors will not be counted if an OOF or AIS condition is
present. When 1, framing errors will be counted regardless of the presence of an OOF or AIS condition.
