0x09—APSTHRESH (APS Threshold Control Register)
The APSTHRESH register sets the threshold value for Signal Fail and Signal Degrade Alarm generation. Bits
7–4 are the signal fail threshold exponent (default = 10
(default = 10
0x55—B1CNTH (Section BIP Error Counter [High Byte])
The B1CNTH counter tracks the number of Section BIP errors.
