Parameter Description:
liu_id
The identifier of the T1/E1 Line Interface Unit in the range 0 to one less than
the number of LIUs fitted. This parameter can also be set to the special value
0x83 to select the signaling processor instead of an LIU. In this case timeslots
0 ... 3 correspond to signaling processor 0 ... 3 respectively.
sc_channel
The channel number of the first channel to be used on the CT bus. This must
be in the range from 0 up to one less than the total number of channels on
the CT bus.
ts_mask
A 32 bit timeslot mask where each bit position is set to 1 if the corresponding
timeslot on the T1/E1 interface is required to be connected to the CT bus. The
least significant bit (bit 0) represents timeslot 0. Each timeslot for which the
corresponding bit is set in ts_mask is connected up to the CT bus, other
timeslots are not affected in any way.
