Receive Out of Frame Defect State
This READ-ONLY bit indicates whether or not the Receive E1 Framer block
is currently declaring the “Out of Frame” defect condition within the incom-
ing E1 data-stream, as described below.
Out of Frame defect condition is declared when “FASC” number of consecu-
tive errored FAS patterns are detected, where “FASC” indicates the Loss of
FAS Alignment Criteria in the Framing Control Register (0xn10B), bit 2-0.
0 – The Receive E1 Framer block is NOT currently declaring the “Out of
Frame” defect condition.
1 – The Receive E1 Framer block is currently declaring the “Out of Frame”
defect condition.

Receive Alarm Indication Status Defect State
This READ-ONLY bit indicates whether or not the Receive E1 Framer block
is currently declaring the AIS defect condition within the incoming E1 data-
stream, as described below.
AIS defect is declared when AIS condition persists for 250 microseconds (2
frames). AIS defect is cleared when more than 2 zeros are detected in two
consecutive frames (250us)
0 – The Receive E1 Framer block is NOT currently declaring the AIS defect
condition.
1 – The Receive E1 Framer block is currently declaring the AIS defect con-
dition.

Change of CAS Multiframe Yellow Alarm Interrupt Status
.
This Reset-Upon-Read bit field indicates whether or not the CAS multiframe
yellow alarm interrupt has occurred since the last read of this register.
If this interrupt is enabled, then the Receive E1 Framer block will generate
an interrupt in response to either one of the following conditions.
1.
Whenever the Receive E1 Framer block declares the CAS Multiframe
Yellow Alarm.
2.
Whenever the Receive E1 Framer block clears the CAS Multiframe
Yellow Alarm
CAS Multiframe Yellow Alarm is declared whenever the received ‘y’ bit in
Time Slot 16 of Frame 0 is set to ‘1’.
0 = Indicates that the “Change of CAS Multiframe Yellow Alarm” interrupt
has not occurred since the last read of this register.
1 = Indicates that the “Change of CAS Multiframe Yellow Alarm” interrupt
has occurred since the last read of this register.

0
Framer Receive Loss of Signal (LOS) State
This READ-ONLY bit indicates whether or not the Receive E1 framer is cur-
rently declaring the Loss of Signal (LOS) condition within the incoming DS1
data-stream, as described below
LOS defect is declared when LOS condition persists for 175 consecutive
bits. LOS defect is cleared when LOS condition is absent or when the
received signal reaches a 12.5% ones density for 175 consecutive bits.
0 = The Receive DS1 Framer block is NOT currently declaring the Loss of
Signal (LOS) condition.
1 = The Receive DS1 Framer block is currently declaring the Loss of Signal
(LOS) condition.
