Channel signaling control
These bits determine the selection of signaling conditioning.
00 = No signaling data is inserted into input PCM data
(passthrough).
01 = Signaling data is inserted from TSCRs.
10 = Signaling data is inserted from TxOH input while TxMUXEN=0
and
TxIMODE[1:0]=00, otherwise is inserted from TxSIG input.
11 = No signaling. For xyxx bits only, x's are from TSCR and y is the
alarm
condition.
