Configuring the Auxiliary Interface

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 14. The asynchronous auxiliary port supports hardware flow control and modem control. Table 7 lists the pinout for this port.
