AISD
Alarm Indication Signal
The alarm indication signal detection is always active regardless if
the interrupt generation is disabled. This bit indicates the AIS
activity. An interrupt will not occur unless the AISIE is set to "1" in
the channel register 0x04h and GIE is set to "1" in the global regis-
ter 0xE0h.
0 = No Alarm
1 = An all ones signal is detected

RLOS
Receiver Loss of Signal
The receiver loss of signal detection is always active regardless if
the interrupt generation is disabled. This bit indicates the RLOS
activity. An interrupt will not occur unless the RLOSIE is set to "1"
in the channel register 0x04h and GIE is set to "1" in the global
register 0xE0h.
0 = No Alarm
1 = An RLOS condition is present
RO
0
D0
QRPD
Quasi Random Pattern Detection
The quasi random pattern detection is always active regardless if
the interrupt generation is disabled. This bit indicates that a QRPD
has been detected. An interrupt will not occur unless the QRPDIE
is set to "1" in the channel register 0x04h and GIE is set to "1" in
the global register 0xE0h.
0 = No Alarm
1 = A QRP is detected
