The SDCMODE alarm bit selects the Signal Degrade BERM window size to use for clearing
alarms. When SDCMODE is a logic 0, the SD BERM will clear an alarm using the same
window size used for declaration. When SDCMODE is a logic 1, the SD BERM will clear an
alarm using a window size that is 8 times longer than alarm declaration window size. The
declaration window size is defined by the SBER SD BERM Accumulation Period register.
The SDSMODE bit selects the Signal Degrade BERM saturation mode. When SDSMODE is
a logic 0, the SD BERM will saturate the BIP count on a per frame basis using the SBER SD
Saturation Threshold register value. When SDSMODE is a logic 1, the SD BERM will
saturate the BIP count on a per window subtotals accumulation period basis using the SBER
SD Saturation Threshold register value.
