Fallback Switching | Western Telematic AFS-16-1 specification

Getting Started

3.Review Help Menu: If you are communicating with the AFS-16 via the text interface (SSH, Telnet or Modem), type /H and press [Enter] to display the Help Menu, which lists all available AFS-16 commands. Note that the Help Menu is not available via the Web Browser Interface.

3.4.Fallback Switching

A/B fallback switching can be controlled via the Text Interface or via the Web Browser Interface.

3.4.1.Fallback Switching - Text Interface

Access the AFS-16 Text Interface as described in Section 3.3 and then proceed as follows:

1.Review the Help Menu: At the Text Interface command prompt, type /H and press [Enter] to display the Help Menu, which provides a basic listing of all available AFS-16 commands.

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 switch to the “A” path.
