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 datastreams or 16/21 E1
datastreams 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 G747 Mode, these bits have
no affect in the G747 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 = replace data from LTDAT with AIS
1 = allow normal data from LTDAT to flow through to the multiplexer
