Description
The jumper caps should be installed (which means grounded) if the
transmit and receive resistance is 75 ohms.
The jumper caps should be removed (which means ungrounded) if the
transmit and receive resistance is 120 ohms.
Generally, the coaxial cables connected to the E1 port are unbalanced cables with the resistance of 75
ohms; the twisted pairs connected to the E1 port are balanced cables with the resistance of 120 ohms.
The interference source can affect the transmission of analog signals to a great extent. Therefore, the
connection mode and grounding mode must be correct and reliable; otherwise, bit error or error message
about signal loss may occur.
