Connecting an Asynchronous Modem to the Console Port
Note To connect an asynchronous modem to the console port, you must have an optional router modem cable.
Contact your router vendor to order this cable.
Figure 4-11 shows an asynchronous modem connected to the console port on the router. Although the
figure shows a Cisco Secure Router 520 Ethernet-to-Ethernet router, this procedure applies to all Cisco
Secure Router 520 Series routers.
