Line Code Violation / Counter Overflow
This bit serves a dual purpose. By default, this bit monitors the line
code violation activity. However, if bit 7 in register 0xE5h is set to a
"1", this bit monitors the overflow status of the internal LCV
counter. An interrupt will not occur unless the LCV/OFIE 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 line code violation, bipolar violation, or excessive zeros has
occurred
This Bit is Reserved
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
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
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
