Transmit Transparency Registers.

TTR1.0
1=this DS0 channel is transparent
Each of the bit positions in the Transmit Transparency Registers (TTR1/TTR2/TTR3) represent a DS0
channel in the outgoing frame. When these bits are set to a 1, the corresponding channel is transparent (or
clear). If a DS0 is programmed to be clear, no robbed bit signaling will be inserted nor will the channel
have Bit 7 stuffing performed. However, in the D4 framing mode, bit 2 will be overwritten by a 0 when a
Yellow Alarm is transmitted. Also the user has the option to prevent the TTR registers from determining
which channels are to have Bit 7 stuffing performed. If the TCR2.0 and TCR1.3 bits are set to 1, then all
24 T1 channels will have Bit 7 stuffing performed on them regardless of how the TTR registers are
programmed. In this manner, the TTR registers are only affecting which channels are to have robbed bit
signaling inserted into them. Please see Figure 13-9 for more details.
