Bit 14: Parity Error Count (PEC) – When 0, BIP-8 block errors (EM byte) are detected (no more than one per
frame). When 1, BIP-8-bit errors are detected (up to 8 per frame).
Bit 13: Receive HDLC Data Link Source (DLS) – When 0, the receive HDLC data link will be sourced from the
GC byte. When 1, the receive HDLC data link will be sourced from the NR byte.
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, parity errors, and REI errors will not be counted if an
OOF or AIS condition is present. Parity errors and REI errors will also not be counted during the E3 frame in which
an OOF or AIS condition is terminated, and the next E3 frame. When 1, framing errors, parity errors, and REI
errors will be counted regardless of the presence of an OOF or AIS condition.
