Throughput delay and Message Mode control
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 local ST-BUS output is from the local ST-BUS input.
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 local ST-BUS output is from the 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 local 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 local ST-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 local ST-BUS output channel.
Per-channel BER pattern; the pseudo random BER test pattern will be presented to
the local ST-BUS output channel.
Per-channel high-impedance. The local ST-BUS output is high-impedance.
