14.
Each of the 24 T1 channels in the transmit direction of the framer can be either forced to be transparent or
in other words, can be forced to stop Bit 7 Stuffing from overwriting the data in the channels.
Transparency can be invoked on a channel by channel basis by properly setting the TTR1, TTR2, and
TTR3 registers.
Each of the bit position 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 Bit 7 stuffing will be performed. However, in the D4
framing mode, bit 2 will be overwritten by a zero 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. Please see Figure 21-7 for
more details.
