Connecting to the Console and Auxiliary Ports
Note The console and auxiliary ports are both asynchronous serial ports; any devices
connected to these ports must be capable of asynchronous transmission.
Asynchronous is the most common type of serial device; for example, most
modems are asynchronous devices.
PRP Console Port Signals
The console port on the PRP is a DCE RJ-45 receptacle. Table 3-1 lists the
signal-to-pin correspondence for the PRP console port.
PRP Auxiliary Port Signals
The auxiliary port on the PRP is a DTE, RJ-45 plug for connecting a modem or
other DCE device (such as a CSU/DSU or another router) to the router. The port
is labeled AUX, as shown in
Figure 3-11. The asynchronous auxiliary port
supports hardware flow control and modem control. Table 3-2 lists the
signal-to-pin correspondence for the PRP auxiliary port.
