SDCMODE:
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.
SDSMODE:
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.
SDBERTEN:
The SDBERTEN bit enables automatic monitoring of line bit error rate threshold events by the
Signal Degrade BERM. When SDBERTEN is a logic one, the SD BERM continuously
monitors line BIP errors over a period defined in the BERM configuration registers. When
SDBERTEN is a logic zero, the SD BERM BIP accumulation logic is disabled, and the BERM
logic is reset to restart in the declaration monitoring state.
