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).

Caution 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 ↓.
