Bits 0 to 11 / Receive AIS Generation Control for T1 Ports 17 to 28 (AIS17 to AIS28). These bits
determine whether the device will replace the demultiplexed T1/E1 datastream with an unframed all ones
AIS signal. AIS17 controls the data at LRDAT17, AIS18 controls the data at LRDAT18, and so on.
Since ports 17 to 28 are not active in the E3 Mode, these bits have no affect in the E3 Mode. Since ports
4, 8, 12, 16, 20, 24, and 28 are not active in the G747 Mode, the AIS20, AIS24 and AIS28 bits have no
affect in the G747 Mode.
0 = send AIS to the LRDAT output
1 = send normal data to the LRDAT output

Bits 0 to 15 / Transmit AIS Generation Control for T1/E1 Ports 1 to 16 (AIS1 to AIS2). These bits
determine whether the device will replace the data input from the 28 T1 datastreams or 16/21 E1
datastreams with an unframed all ones AIS signal. AIS1 controls the data from LTDAT1, AIS2 controls
the data from LTDAT2, and so on. Since ports 4, 8, 12, 16, 20, 24, and 28 are not active in the G747
Mode, the AIS4, AIS8, AIS12 and AIS16 bits have no affect in the G747 Mode.
0 = replace data from LTDAT with AIS
1 = allow normal data from LTDAT to flow through to the multiplexer
