NAME AND DESCRIPTION
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).

NAME AND DESCRIPTION
MSB of the Idle Code (this bit is transmitted first)
LSB of the Idle Code (this bit is transmitted last)
11.2 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.
