00 = LAPD Controller/SLC96 Buffer. The data link bits are extracted
from the LAPD controller. (LAPD1 is the only controller that can be
used to extract LAPD messages through the data link bits)
01 = Serial Input. The data link bits are extracted to the serial data out-
put.
10 = Overhead Input. The data link bits are extracted to the overhead
output.
11 = None (forced to 1). The data link bits are forced to 1.

OTE: For E1, Ch. 0 is not applicable since it carries FAS and National
Bits in alternating frames. This register is only relevant if the
Framing Channel is using Channel Associated Signaling
