Modular Serial 120 ohm RJ45 to RJ45 terminator Cable connections.
120 ohm RJ45 to RJ45 cable connections are as follows:
One end (RJ45) connects to the router.
The other end (RJ45) is connected to the network side device.

If the connection distance is long, you can use a 120 ohm relay extension cable to extend the cable.
The connection method of the 120-ohm trunk extension cable is to connect one end (RJ45) to the network port connector, and the other end (RJ45) to the peer network device, as shown in Figure 7-14.
