Throughput Delay and Message Control Bits: These three bits control the
backplane CT-Bus input or output.
Source Stream Address Bits: These five bits refer to the number of the data stream
for the source (backplane or local) connection.

memory is the local data memory address of the switched input channel and stream.
The backplane ST-BUS output is from local ST-BUS input.
memory is the local data memory address of the switched input channel and stream.
The backplane ST-BUS output is from local ST-BUS input.
Per-channel variable delay from backplane interface; the content of the connection
memory is the backplane data memory address of the switched input channel and
stream. The backplane ST-BUS output is from the backplane CT-Bus input.
Per-channel constant delay from the backplane interface; the content of the
connection memory is the backplane data memory address of the switched input
channel and stream. The backplaneST-BUS output is from backplane CT-Bus input.
Per-channel message mode; only the lower byte (bits 7 to 0) of the connection
memory location will be presented to the backplaneST-BUS output channel.
Per-channel BER pattern; the pseudo random BER test pattern will be presented to
the backplaneST-BUS output channel.
