Push button
The push button initiates a reset.
Also LEDs 1-3 are activated for the period during which the pushbutton is actuated, and
the DR relay is deactivated if it was activated. This makes possible a functional check of
these signalling elements.
The LED states during putting into operation are shown in the following six steps (for the
structure, see Figure 12).
Here, “ * ” means any undefined LED state (MAKE / BREAK / FLASHING).
Preconditions for putting into operation:
The jumper positions must correspond to the required operating mode / baud rate in both
KU–XGs (KU–XG1, KU–XG2).
Step 1 KU–XG1 is in the Power On state and the opposite terminal KU–XG2 is in the Power Off state
KU–XG1 KU–XG2
LED1 MAKE LED1 BREAK
LED2 * LED2 BREAK
LED3 * LED3 BREAK
LED4 MAKE LED4 BREAK
Step 2 Apply the interface (X.21 / G.703) on KU–XG1
KU–XG1 KU–XG2
LED1 BREAK LED1 BREAK
LED2 * LED2 BREAK
LED3 * LED3 BREAK
LED4 MAKE LED4 BREAK
