AUXP state
This READ ONLY bit indicates whether or not the Receive E1
Framer Block is currently detecting Auxiliary (101010....) pattern.
0 = Indicates that the Receive E1 Framer Block is NOT currently
detecting the Auxiliary (101010....)Pattern.
1 = Indicates that the Receive E1 Framer Block is currently detect-
ing the Auxiliary (101010....)Pattern.

Change in Auxiliary Pattern interrupt Status
This Reset-Upon-Read bit field indicates whether or not the
“Change in Auxiliary Pattern” 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 detects the Auxiliary
Pattern.
2.
Whenever the Receive E1 Framer block no longer detects the
Auxiliary Pattern
0 = Indicates that the “Change in Auxiliary Pattern” interrupt has not
occurred since the last read of this register
1 = Indicates that the “Change in Auxiliary Pattern” interrupt has
occurred since the last read of this register

CRC-4-to-non-CRC-4 interworking state
This READ ONLY bit indicates the status of CRC-4 interworking sta-
tus when Annex B is enabled. (MODENB bit in register 0xn107)
When Annex B is enabled, G.706 Annex B CRC-4 multiframe align-
ment algorithm is implemented. If CRC-4 alignment is enabled and
not achieved in 400msec while the basic frame alignment signal is
present, it is assumed that the remote end is a non CRC-4 equip-
ment. Then, a CRC-to-Non-CRC interworking interrupt status will be
generated.
0 = Indicates CRC-4 to non-CRC-4 interworking is NOT established.
1 = Indicates CRC-4 to non-CRC-4 interworking is established.
