Throughput Delay and Message Mode Control
000
Per-channel variable delay from local interface; the content of the 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.
001
Per-channel constant delay from local interface; the content of the 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.
010
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.
011
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.
100
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.
101
Per-channel BER pattern; the pseudo random BER test pattern will be presented to
the backplaneST-BUS output channel.
110
Per-channel input. The backplane ST-BUS is input
