SDBERTEN

SFSMODE
SFBERTEN
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.
All SD BERM configuration registers should be set up before the monitoring is enabled.
The SFCMODE alarm bit selects the Signal Failure BERM window size to use for clearing
alarms. When SFCMODE is a logic 0, the SF BERM will clear an alarm using the same
window size used for declaration. When SFCMODE is a logic 1, the SF 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 SF BERM Accumulation Period register.
The SFSMODE bit selects the Signal Failure BERM saturation mode. When SFSMODE is a
logic 0, the SF BERM will saturate the BIP count on a per frame basis using the SBER SF
Saturation Threshold register value. When SFSMODE is a logic 1, the SF BERM will
saturate the BIP count on a per window subtotals accumulation period basis using the SBER
SD Saturation Threshold register value.

logic is reset to restart in the declaration monitoring state.
