DIP SW1-1
ON/OFF
First E1channel loop-back control switch. When it is set ON, the first 2M bit/s
data stream of remote terminal will loop-back to local terminal.
When the equipment is operating in normal, it is at OFF.
DIP SW1-2
ON/OFF
Second E1channel loop-back control switch. When it is set ON, the first 2M
bit/s data stream of remote terminal will loop-back to local terminal. When
the equipment is operating in normal, it is at OFF.
DIP SW1-3
ON/OFF
Third E1channel loop-back control switch. When it is set ON, the first 2M
bit/s data stream of remote terminal will loop-back to local terminal. When
the equipment is operating in normal, it is at OFF.
DIP SW1-4
ON/OFF
Fourth E1channel loop-back control switch. When it is set ON, the first 2M
bit/s data stream of remote terminal will loop-back to local terminal. When
the equipment is operating in normal, it is at OFF.
DIP SW1-5
ON/OFF
It switches the alarm display of first E1 channel. When it is set ON, the LED
CH1 will indicate the loss of E1 input signal. When it is set OFF, the LED
CH1 will be shut off, and doesn’t
Indicate the loss of E1 input signal even if the tributary occurs alarm. When
the equipment is operating in normal, it is at OFF.
DIP SW1-6
ON/OFF
It switches the alarm display of second E1 channel. When it is set ON, the
LED CH2 will indicate the loss of E1 input signal. When it is set OFF, the
LED CH2 will be shut off, and doesn’t
Indicate the loss of E1 input signal even if the tributary occurs alarm. When
the equipment is operating in normal, it is at OFF.
DIP SW1-7
ON/OFF
It switches the alarm display of third E1 channel. When it is set ON, the LED
CH3 will indicate the loss of E1 input signal. When it is set OFF, the LED
CH3 will be shut off, and doesn’t
Indicate the loss of E1 input signal even if the tributary occurs alarm. When
the equipment is operating in normal, it is at OFF.
