Receive Channel Mark Control Bits
0 =do not affect the receive data associated with this channel
1 = replace the receive data associated with this channel with
either the idle code or the digital milliwatt code (depends on
the RCR2.7 bit)
15.2.2 Per–Channel Code Insertion
The second method involves using the Receive Channel Control Registers (RCC1/2/3) to determine
which of the 24 T1 channels off of the T1 line and going to the backplane should be overwritten with the
code placed in the Receive Channel Registers (RC1 to RC24). This method is more flexible than the first
in that it allows a different 8–bit code to be placed into each of the 24 T1 channels.
