Connecting to the Auxiliary Port
To connect a modem to the auxiliary port on the router, perform the following procedure:
Step 1 Use the black RJ-45-to-DB-25 modem adapter cable to connect the router to a modem. (See Figure 3-61
through Figure 3-64.)
For information about auxiliary port pinouts, refer to the Cisco Modular Access Router Cable
Specifications document available online and on the Documentation CD-ROM.
Note On the Cisco routers, the auxiliary port is color-coded black.
Step 2 Make sure that your modem and the router auxiliary port are configured for the same transmission speed
(up to 115200 bps is supported) and hardware flow control with data carrier detect (DCD) and data
terminal ready (DTR) operations.
