Throughput Delay and Message Channel Control Bits:
These three bits control the
local ST-BUS output.
12 - 8
LSAB4 -
LSAB0
Source Stream Address Bits:
These five bits refer to the number of the data stream for
the source (local or backplane) connection.
7 - 0
(See
Note 1)
LCAB7 -
LCAB0
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 local LSTo streams.

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 local 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 local 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 local 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 local ST-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 local ST-BUS output channel.
101
Per-channel BER pattern; the pseudo random BER test pattern will be presented to
the local ST-BUS output channel.
110
Per-channel high impedance. The local ST-BUS output is high-impedance.
