6.4 T1 / E1 AIS GENERATION CONTROL REGISTER DESCRIPTION
Via the T1/E1 Alarm Indication Signal (AIS) Control Registers, the Host can configure the DS3112 to
generate an unframed all ones signal in either the transmit or receive paths on the 28 T1 ports or the 16/21
E1 ports. On reset, the device will force AIS in both the transmit and receive paths and it is up to the
Host to modify the T1/E1 AIS Generation Control Registers to allow normal T1/E1 traffic to traverse the
DS3112. See the Block Diagrams in Section 1 for details on where the AIS signal is injected into the data
flow. When the M13/E13 multiplexer function is disabled in the DS3112 (see the UNCHEN control bit
in the Master Control Register 1 in Section 4.2 for details), the T1/E1 AIS Generation Control Registers
are meaningless and can be set to any value.

Note: Bits that are underlined are read only; all other bits are read-write.
Bits 0 to 15 / Receive AIS Generation Control for T1/E1 Ports 1 to 16 (AIS1 to AIS2). These bits
determine whether the device will replace the demultiplexed T1/E1 datastream with an unframed all ones
AIS signal. AIS1 controls the data at LRDAT1, AIS2 controls the data at LRDAT2, 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 = send AIS to the LRDAT output
1 = send normal data to the LRDAT output
