Description
Center Receive Elastic Buffer
Only applicable if the time slot assigner is disabled (PC(3:1).RPC(3:0) =
´0001
A transition from low to high forces a receive slip and the read- pointer of
the receive elastic buffer is centered. The delay through the buffer is set
to one half of the current buffer size. It should be hold high for at least two
2.048 MHz periods before it is cleared.
Description
Select CMI Precoding (T1 only)
Only valid if CMI code (MR0.XC(1:0) = ´01
the CMI precoding and influences transmit and receive data.
Note: Before local loop is closed, B8ZS precoding has to be switched off.
