IDLE CODE INSERTION
The transmit idle registers (TIR1/2/3/4) determine which of the 32 E1 channels should be overwritten
with the code placed in the transmit idle-definition register (TIDR). This allows the same 8-bit code to be
placed into any of the 32 E1 channels.
Each of the bit positions in the TIRs represents a DS0 channel in the outgoing frame. When these bits are
set to 1, the corresponding channel transmits the idle code contained in the TIDR.
