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 backplane CT-Bus output is from 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 backplane CT-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 CT-Bus output is from backplane
CT-Bus input.
Per-channel constant 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 CT-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 the presented to the backplane CT-Bus
output channel.
Per-channel BER pattern; the pseudo random BER test pattern will be
presented to the backplane CT-Bus output channel.
Per-channel input. The backplane CT-Bus is input.

BSAB4 - BSAB0 Source Stream Address Bits: These five bits refer to the number of the data streams
for the source (local or backplane) connection.
7-0
(See
Note 1)
BCAB7 - BCAB0 Source Channel Address Bits: These eight bits refer to the number of the channel that
is the source (local or backplane) connection.
Note 1: Only Bits 7-0 will be used for per-channel message mode for the backplane STio streams.
