PRELIMINARY
3.3
As shown in
the input/output data handler with the programmed connections. The I/O controller
handles all lines operating at the same or different data rate. To establish a connection
the user must only program the source line with time-slot and the destination line with
the time-slot. The internal controller (data handler) writes the connection in a connection
descriptor list and stores this list in the connection data handler. The programming
procedure is described in
data memory controlled by the input handler. The output handler controls the constant,
minimum delay and subchannel switching.
3.3.1
The SWITI family supports a various number of switching modes. All modes are
described in the following chapters.
3.3.1.1
Each connection independent of the addressed buses can be determined to be a
constant delay or minimum delay connection. Constant delay means that any input time-
slot or subchannel is available on the programmed output after 2 frames. Minimum delay
means that the time-slot appears at the output as soon as possible. The minimum delay
depends on the chosen connections and the possible range is between 0 and 2 frames,
up to 3 frames in rare cases.
An application note which describes the possible connection and minimum delays is
available.
3.3.1.2
Subchannel switching has a constant delay of 2 frames. Every connection can be 1-bit,
2-bit, 4-bit, or normal 8-bit connection. It is possible to combine every kind of subchannel
connection, e.g. two 1-bit time-slots with one 4-bit time-slot to one output time-slot.
Please refer to
3.3.1.3
As described in the overview the multipoint-switching allows to switch several input time-
slots to one output time-slot. All input data are logical AND or OR connected. This mode
is selectable with the multipoint connection command. The setup (logical AND or OR) for
the last connection determines all other previous programmed multipoint connections.
Multipoint switching has always a constant delay. Subchannel switching is not
supported.
