Connecting a Modem to the Auxiliary Port

To connect a modem to the auxiliary port on the router, follow these steps:

Step 1 Use the black RJ-45-to-DB-25 modem adapter cable to connect the router to a modem. (See Figure 24 and Figure 25.)

Step 2 Make sure that your modem and the router auxiliary port are configured for the same transmission speed (up to 115,200 bps is supported) and hardware flow control, with data carrier detect (DCD) and data terminal ready (DTR) enabled.
