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.
mode = 6 : Remove a duplex connection between 2 timeslots on the CT bus
and 1 timeslot on the local bus. Using parameters local_stream and
local_slot, to specify both timeslots for disconnection.
mode = 10 : Generate a fixed pattern (e.g., idle pattern) on a local timeslot.
local_stream specifies the liu_id, local_slot the timeslot, and pattern the 8 bit
data to be output on the timeslot.
mode = 11 : Make a simplex connection between two local bus timeslots
(without using the CT bus). In this case, source_stream and source_slot
specify the source of the signal in terms of liu_id and timeslot respectively.
local_stream and local_slot specify the outgoing timeslot.
mode = 12 : Make a duplex connection between two local bus timeslots
(without using the CT bus). In this case, source_stream and source_slot
specify one timeslot in terms of liu_id and timeslot, whilst local_stream and
local_slot specify the other timeslot.
source_stream
The source stream references which of the CT bus streams is used as a
source of data. The parameter takes values in the range 0 … 31. For some
modes (e.g., 11 and 12), this field is used to specify a local_stream instead of
a CT bus stream.
source_slot
The source slot references the CT bus timeslot from which to connect or
disconnect to the local stream. The source slot value has the following ranges
depending on the CT bus speed.
CT bus speed Source Slot Range
4 Mbps 0 ... 63
8 Mbps 0 … 128
