PLS-345 - Physical Layer Switch; User's Guide
7.2. Code Activated A/B Switching
The PLS offers three different commands for controlling A/B switching:
The /A command, which is used to switch one or more circuits to the "A" line.
The /B command, which is used to switch one or more circuits to the "B" line.
The /D command, which is used to switch all three circuits to their
All three of these commands are available in both System Mode and User Mode.
7.2.1.The /A Command and the /B Command
The /A command and the /B command can be used to control the "A" or "B" position of one or more of the A/B circuits. The /A command will switch one or more circuits to the "A" line, and the /B command will switch one or more circuits to the "B" line.
Both the /A command and the /B command use the following format:
/A <n> [Enter] or /B <n> [Enter]
Where, n is one of the following:
Switch One Circuit: To switch one A/B circuit, enter the number or common name of the desired circuit. For example, to switch circuit 2 to the "A" position, type
/A 2 [Enter].
Switch Two Circuits: To switch two circuits to the same A/B position, enter the numbers or common names of the desired circuits with a "plus" sign (+) between them (e.g. n+N). For example to switch circuits 1 and 3 to the "B" position, type /B 1+3 [Enter].
Switch All Circuits: To switch all three A/B circuits to the same A/B position, enter an asterisk (*) in place of the circuit number or name. For example, to switch all three circuits to the "A" position, type /A * [Enter].
