Note: Bits that are underlined are read-only; all other bits are read-write.
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 data streams or 16/21 E1 data streams 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 G.747 Mode, the AIS4, AIS8, AIS12, and AIS16
bits have no affect in the G.747 mode.

Note: Bits that are underlined are read-only; all other bits are read-write.
Bits 0 to 11: Transmit AIS Generation Control for T1 Ports 17 to 28 (AIS17 to AIS28). These bits determine
whether the device will replace the data input from the 28 T1 data streams or 16/21 E1 data streams with an
unframed all ones AIS signal. AIS17 controls the data from LTDAT17, AIS18 controls the data from LTDAT18,
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
22 to 28 are not active in the G.747 mode, these bits have no affect in the G.747 mode. Since ports 4, 8, 12, 16, 20,
24, and 28 are not active in the G.747 mode, the AIS20, AIS24, and AIS28 bits have no effect in the G.747 mode.
0 = replace data from LTDAT with AIS
1 = allow normal data from LTDAT to flow through to the multiplexer
0 = replace data from LTDAT with AIS
