Bit #
Name
Default
Bit 0/Lower CAS Align/Alarm Word (LCAW). Selects the lower CAS align/alarm bits (xyxx) to be sourced from the lower
4 bits of the TS1 register.
Bits 1 to 7/Software Signaling Insertion Enable for LCAW and Channels 16 to 22 (CH16 to CH22). These bits determine
which channels are to have signaling inserted form the Transmit Signaling registers.

Bit #
Name
Default
Bits 0 to 7/Software Signaling Insertion Enable for Channels 23 to 30 (CH23 to CH30). These bits determine which
channels are to have signaling inserted form the transmit signaling registers.
0 = do not source the lower CAS align/alarm bits from the TS1 register
1 = source the lower CAS alarm align/bits from the TS1 register
0 = do not source signaling data from the TSx registers for this channel
1 = source signaling data from the TSx registers for this channel
0 = do not source signaling data from the TS registers for this channel
1 = source signaling data from the TS registers for this channel
