Bit 7 - Insert AIS Rx DS1 Channel 3
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 3 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data3 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 2
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 2 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data2 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 5 - Insert AIS Rx DS1 Channel 1
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 1 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data1 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 0
This “Read/Write” bit-field permits the user to config-
ure the contents of the “inbound” DS1 Channel 0 to
be overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits data to be output
(via the RxDS1Data0 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 3
This “Read/Write” bit-field permits the user to config-
ure the contents of the “output” DS1 Channel 3 to be
overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 3 to be transmitted as received (via the
TxDS1Data3 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 2
This “Read/Write” bit-field permits the user to config-
ure the contents of the “output” DS1 Channel 3 to be
overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 2 to be transmitted as received (via the
TxDS1Data2 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 1
This “Read/Write” bit-field permits the user to config-
ure the contents of the “output” DS1 Channel 1 to be
overwritten with an “All Ones” pattern.
Setting this bit-field to “0” permits the contents of DS1
Channel 1 to be transmitted as received (via the
TxDS1Data1 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 0
This “Read/Write” bit-field permits the user to config-
ure the contents of the “output” DS1 Channel 0 to be
overwritten with an “All Ones” pattern.
