1=insert data from the TC32 register into the transmit data stream
8.2 RECEIVE SIDE CODE GENERATION
On the receive side, the Receive Channel Control Reg-
isters (RCC1/2/3/4) are used to determine which of the
32 E1 channels off of the E1 line and going to the back-
plane should be overwritten with the code placed in the
Receive Channel Registers (RC1 to RC32).
