The auxiliary port on the PRP is a DTE, RJ-45 receptacle for connecting a modem 
or other DCE device (such as a CSU/DSU or another router) to the router. The 
asynchronous auxiliary port supports hardware flow control and modem control.

See the 

 for additional information about the auxiliary port.

Refer to 

 and use the following procedure to connect an asynchronous 

serial device to the PRP auxiliary port.

Power off the asynchronous serial device.

Attach the device end of the cable to the interface port on the asynchronous serial 
device.

Attach the other end of the cable to the PRP auxiliary port.

Power on the asynchronous serial device.

Two RJ-45 Ethernet interface receptacles on the PRP provide media-dependent 
interface (MDI) Ethernet ports. These connections support IEEE 802.3 and 
IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards. 
The transmission speed of the Ethernet ports is autosensing by default and is 
user-configurable.

The RJ-45 receptacles on the PRP provide two physical connection options for 
Ethernet interfaces. To connect cables to the PRP Ethernet interfaces (ports 
labeled ETH0 and ETH1), attach the Category 5 UTP cable directly to a RJ-45 
receptacle on the PRP.

See the 

 for additional 

information.
