REV. 1.0.6
Setting this bit-field to “0” permits the contents of DS1
Channel 14 to be transmitted as received (via the
TxDS1Data14 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).
Bit 1 - Insert AIS Tx DS1 Channel 13
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 13 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 13 to be transmitted as received (via the
TxDS1Data13 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 12
This “Read/Write” bit-field permits the user to config-
ure the contents of the “outbound” DS1 Channel 12 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 12 to be transmitted as received (via the
TxDS1Data12 input pin).
Setting this bit-field to “1” configures the XRT72L13
M13 device to overwrite this data with an AIS (all
ones pattern).

Bit 7 - Insert AIS Rx DS1 Channel 19
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 19 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data19 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 6 - Insert AIS Rx DS1 Channel 18
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 18 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data18 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).
