A logic 1 in any bit position of these registers indicates which maintenance or
alarm status has changed state.
RRAI, AISDI, REDI, and AISI:
RRAI, AISDI, REDI, and AISI indicate when the corresponding E1-FRMR
Maintenance/Alarm Status register bit has changed state from logic 0 to logic
1 or vice-versa. These bits are cleared when this register is read.
FEBEI:
The FEBEI bit becomes a logic one when a FEBE indication is received in the
Si bits of frames 13 or 15. This bit is cleared when this register is read.
CRCEI:
The CRCEI bit becomes a logic one when a calculated CRC differs from the
received CRC remainder. This bit is cleared when this register is read.
