TIR1.0-3.7
Transmit Idle Code Insertion Control Bits.
0 = do not insert the Idle Code in the TIDR into this channel
1 = insert the Idle Code in the TIDR into this channel
NOTE:
If CCR4.0=1, then a 0 in the TIRs implies that channel data is to be sourced from TSER and a 1 implies
that channel data is to be sourced from the output of the receive side framer (i.e., Per–Channel Loopback;
see Figure 1–1).

RECEIVE SIDE CODE GENERATION
The Receive Mark Registers (RMR1/2/3) are used to determine which of the 24 T1 channels should be
overwritten with either a 7Fh idle code or with a digital milliwatt pattern. The RCR2.7 bit will determine
which code is used. The digital milliwatt code is an eight-byte repeating pattern that represents a 1 kHz
sine wave (1E/0B/0B/1E/9E/8B/8B/9E). Each bit in the RMRs, represents a particular channel. If a bit is
set to a 1, then the receive data in that channel will be replaced with one of the two codes. If a bit is set to
0, no replacement occurs.
