Console Port Signals
The console port is an RJ-45 interface for connecting a terminal to the router. The console port does not
support modem control or hardware flow control and requires a straight-through RJ-45 cable.
Before connecting a terminal to the console port, check the terminal setting for the data transmission
rate, in bits per second (bps). The terminal transmission rate setting must match the default rate of the
console port, which is 9600 bps. Set the terminal to these operational values: 9600bps, 8 data bits, no
parity, 2stop bits (9600 8N 2).
Table 1 -5 lists the signals used on the console port.
Auxiliary Port Signals
The Auxiliary (AUX) port is an RJ-45 interface for connecting a modem or other data communication
equipment (DCE) device (such as another router) to the RSP/RP. The AUX port supports hardware flow
control and modem control.
Table 1 -6 lists the signals used on the auxiliary port.
