0 = do not insert data from the TC register into the transmit data

1 = insert data from the TC register into the transmit data
stream
11.2 RECEIVE SIDE CODE GENERATION
On the receive side, the Receive Channel Control Registers (RCC1/2/3/4) are used to determine which of
the 32 E1 channels off of the E1 line and going to the backplane should be overwritten with the code
placed in the Receive Channel Registers (RC1 to RC32). This method allows a different 8–bit code to be
placed into each of the 32 E1 channels.
