Setting any of the CH[1:24] bits in the RSI1 through RSI4 registers will cause signaling data to be reinserted for the
associated channel. RSI4 is used for 2.048MHz backplane operation.
0 = Force the RCHBLKn pin to remain low during this channel time.
1 = Force the RCHBLKn pin high during this channel time.
When 2.048MHz backplane mode is selected, this register allows the user to enable the channel blocking
signal for any of the 32 possible backplane channels.
When 1.544MHz backplane mode is selected, the LSB of this register determines whether or not the
RCHBLKn signal will pulse high during the F-bit time. In this mode RCBR4.1 to RCBR4.7 should be set to
0.

RCBR4.0 = 0, do not pulse RCHBLKn during the F-bit.
RCBR4.0 = 1, pulse RCHBLKn during the F-bit.
