Throughput Delay and Message Channel Control Bits: These three bits control the
local ST-BUS output.
Source Stream Address Bits: These five bits refer to the number of the data stream for
the source (local or backplane) connection.
Source Channel Address Bits: These eight bits refer to the number of the channel that
is the source (local or backplane) connection.

Table 27 - Local Connection Memory Bits
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.
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.
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 variable delay from local interface; the content of the connection
Per-channel constant delay from local interface; the content of the connection
Per-channel high impedance. The local ST-BUS output is high-impedance.
