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.
2.5 Connecting to the E1/T1 Devices
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
Appendix A 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
