Bit 5 - Insert AIS Rx DS1 Channel 17
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 17 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data17 output pin, as demultiplexed
via the inbound DS2 and DS3 data streams.
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 4 - Insert AIS Rx DS1 Channel 16
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 16 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data16 output pin, as demultiplexed
via the inbound DS2 and DS3 data streams.
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 3 - Insert AIS Tx DS1 Channel 19
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 19 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 19 to be transmitted as received (via the
TxDS1Data19 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 2 - Insert AIS Tx DS1 Channel 18

Setting this bit-field to “0” permits the contents of DS1
Channel 17 to be transmitted as received (via the
TxDS1Data17 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 0 - Insert AIS Tx DS1 Channel 16
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 16 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 16 to be transmitted as received (via the
TxDS1Data16 input pin).
Setting this bit-field to “1” configures the XRT72L13
