TTR1/TTR2/TTR3: TRANSMIT TRANSPARENCY REGISTERS (39h to 3Bh)
(MSB)
Each of the bit positions in the Transmit Transparency Registers (TTR1/TTR2/TTR3) represents 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.
TIR1/TIR2/TIR3: TRANSMIT IDLE REGISTERS (3Ch to 3Eh)
(MSB)
TIDR: TRANSMIT IDLE DEFINITION REGISTER (3Fh)
Each of the bit positions in the Transmit Idle Registers (TIR1/TIR2/TIR3) represents a DS0 channel in
the outgoing frame. When these bits are set to a 1, the corresponding channel will transmit the Idle Code
contained in the Transmit Idle Definition Register (TIDR). Robbed bit signaling and bit 7 stuffing will
occur over the programmed Idle Code unless the DS0 channel is made transparent by the Transmit
Transparency Registers.
