Cisco Systems UBR7100E manual Connecting a Modem to the Auxiliary Port

Chapter 3 Installing Cisco uBR7100 Series Universal Broadband Routers

Connecting the Console Port and Auxiliary Port

Step 3 Attach the DB-9 connector to the appropriate serial connector on the PC or terminal. (See Figure 3-11.)

Step 4 Configure the terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, 2 stop bits, and no flow control.

Note Do not set the terminal emulation software for either hardware or software flow control. Doing so will prevent communications with the router.

Connecting a Modem to the Auxiliary Port

You can use the auxiliary port to connect a terminal or a modem for remote access to the router.

Note For more information about the console port and auxiliary port connectors, see the “Console and Auxiliary Port Cables and Pinouts” section on page C-2.

To connect the auxiliary port to a modem, use the following procedure:

Step 1 Connect one end of the RJ-45 rollover cable to the RJ-45-to-DB-25 adapter (labeled MODEM).

Step 2 Connect the other end of the rollover cable directly to the auxiliary port on the router. (See Figure 3-12.)

Step 3 Attach the DB-25 connector to the modem. (See Figure 3-12.)

Step 4 Make sure that the modem and the auxiliary port on the router are configured for the same transmission speed (38.4 Kbps and 56 Kbps are typical). Configure the modem for auto-answer, and for hardware flow control using the Data Carrier Detect (DCD) and Data Terminal Ready (DTR) signals.
