17.2.3 Software Signaling Insertion Enable Registers, T1 Mode
In T1 mode, only registers SSIE1 through SSIE3 are used since there are only 24 channels in a T1 frame.
Register Name:
Register Description:
Register Address:
Bit #

Default
Bits 0 to 7/Software Signaling Insertion Enable for and Channels 1 to 8 (CH1 to CH8). These bits determine what
channels are to have signaling inserted form the transmit signaling registers.

Default
Bits 0 to 7/Software Signaling Insertion Enable for and Channels 17 to 24 (CH17 to CH24). These bits determine what
channels are to have signaling inserted form the transmit signaling registers.
1 = source signaling data from the TSx registers for this channel
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 TSx registers for this channel
1 = source signaling data from the TSx registers for this channel
0 = do not source signaling data from the TSx registers for this channel
