If a parameter is not required, it must be set to zero.
local_stream
The local stream defines which local stream to use for all the modes of operation. The
local streams are either an liu_id or a special identifier to allow connection to the
signaling processor as follows:
Local Stream
Connected to
0 ... 3
liu_id 0 ... 3
131 (0x83)
Signaling Processor
local_slot
The local slot defines which timeslot on the local stream to use for all the modes of
operation. The local slot value has the following valid ranges depending on the type of
local stream:
Local Stream Type
Local Slot Range
Local stream to E1 LIU
1 … 31
Local stream to T1 LIU
1 … 24
Local stream to signaling processor
0 … 3
mode
The value of the mode parameter determines which of the following operations to
perform.
mode = 1 : Make a simplex connection from a timeslot on the CT bus to a timeslot on
the local bus. Using parameters local_stream, local_slot, source_stream and
source_slot, to specify the local and CT bus timeslots respectively.
mode = 2 : Make a simplex connection from a timeslot on the local bus to a timeslot
on the CT bus. Using parameters local_stream, local_slot, dest_stream and dest_slot,
to specify the local and CT bus timeslots respectively.
mode = 3 : Make a duplex connection between a local stream timeslot and 2 CT bus
timeslots. Using parameters local_stream, local_slot, source_stream and source_slot,
to specify one simplex connection and local_stream, local_slot, dest_stream and
dest_slot, to specify the other simplex connection.
mode = 4 : Remove a simplex connection from a timeslot on the CT bus to a timeslot
on the local bus. Using parameters local_stream and local_slot, to specify the timeslot
for disconnection.
mode = 5 : Remove a simplex connection from a timeslot on the local bus to a
timeslot on the CT bus. Using parameters local_stream and local_slot, to specify the
timeslot for disconnection.
