2. Manual A/B Switching: Use the manual circuit switches to change A/B paths.
Note that this example assumes that the Master A/B Gang Switch and individual
circuit module switches have not been disabled.
a) Master A/B Gang Switch: Toggle the Master A/B Gang Switch between the
“A” and “B” positions. The LED indicators should follow the Master Switch,
indicating that each circuit has switched the “A” and “B” paths.
b) Circuit Module A/B Switch: Choose an individual Circuit Module and toggle
the module’s A/B Switch between “A” and “B”. The LED indicators should
indicate that the module has switched the A/B path.
3. Code Activated Switching: To control A/B fallback switching using ASCII
commands, invoke the following commands at the AFS command prompt:
a) Type /T *,B and press [Enter]. All Circuit Modules should switch to the
“B” path.
b) Type /T 1,A and press [Enter]. Circuit Module number 1 should switch to the
“A” path.
c) Type /T 2,3,4,A and press [Enter]. Circuit Modules 2, 3, and 4 should
