Connecting to the E1/T1 Devices 

2-3 

 illustrates a rear panel of the IPmux-11 unit with two user LAN ports. 

 

 

To connect to the Ethernet user equipment: 
•  Connect IPmux-11 to the Ethernet user equipment using a standard straight 

UTP cable terminated with an RJ-45 connector. 

E1/T1 devices are connected to IPmux-11 via one balanced RJ-45 port designated 
E1/T1. Unbalanced E1 interface is provided via CBL-RJ45/2BNC/E1/X adapter 
cable (see 

 for the connector pinouts and cable wiring diagram).  

 

When connecting balanced E1 or T1 equipment, make sure to use only 4-wire 

RJ-45 connectors with the following pins used for receiving and transmitting data: 
1, 2, 4, 5. Do not use 8-pin RJ-45 connectors. 

 

 

 

To connect to the E1/T1 devices with balanced interfaces: 
•  Connect IPmux-11 to the E1/T1 devices using standard straight E1/T1 cables. 

 

To connect to the E1 devices with unbalanced interfaces: 
1.  Connect the RJ-45 connector of the adapter cable to the IPmux-11 balanced RJ-45 

ports designated E1. 

2.  Connect the transmit cable to the red coaxial connector of the adapter cable 

marked ↑.  

3.  Connect the receive cable to the green coaxial connector of the adapter cable 

marked ↓.
