liu_id
The identifier of the T1/E1/J1 LIU in the range 0 to one less than the number of LIUs.
This parameter can also be set to one of the special values (0x90, 0x91, 0x92 or 0x93)
to select one of the signaling processors instead of an LIU. These values identify
processors 0 to 3 respectively. In this case, timeslots 0 to 31 correspond to a timeslot
on the signaling processor.
timeslot
The timeslot number on the T1/E1/J1 LIU on which the data from the CT Bus will be
transmitted. Valid ranges are:
— For an E1 interface: 1 to 31
— For a T1 interface: 1 to 24
— When referring to the signaling processors: 0 to 31
sc_channel
The channel number on the CT Bus to which the LIU listens. This should be in the
range from 0 to one less than the total number of channels on the CT Bus.

Description
This message is sent to the board to generate a fixed pattern on a specific timeslot of a
T1/E1/J1 LIU. It is typically issued at initialization and whenever a call terminates to
generate an Idle pattern towards the network.
