NAME AND DESCRIPTION
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.
