Auxiliary Port Connections
The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control.
Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the
cable.
For connection to a modem, you must use an RJ-45-to-DB-25 adapter cable. This cable is orderable
separately along with a DB-9-to-DB-25 adapter.
For detailed information about connecting devices to the auxiliary port, see the “Connect to Console
Terminal or Modem” section on page 3-22.
For cable and port pinouts, see the Cisco Modular Access Router Cable Specifications document at
cisco.com.
