2.7 Connecting to the Ethernet Equipment
IPmux-24 is connected to the Ethernet equipment via the fiber optic LC or 8-pin
RJ-45 electrical ports designated NET 1, NET/USER 2 and USER 3. Refer to
Appendix A for the RJ-45 connector pinout.
Figure 2-2 illustrates a typical IPmux-24 rear panel with two fiber optic LC and
one electrical RJ-45 connectors.
³ To connect to the Ethernet equipment with fiber optic interface:
• Connect IPmux-24 to the Ethernet equipment using a standard fiber optic
cable terminated with an LC connector.

2.8 Connecting to the E1/T1 Devices
E1/T1 devices are connected to IPmux-24 via balanced RJ-45 ports designated E1/T1
1–4. 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.
