WHAT TYPE OF MODEM AND CABLE DO I NEED TO DIAL INTO THE AUX PORT OF MY CISCO ROUTER?

Few people still do dial in to a router, but you are right, it is supported and through the AUX port. The modem itself can theoretically be any modem, but common modems like Hayes work the best. You typically need to set the dip switches on the modem for Auto Answer (AA On) or it will ring and not pick up. You can hook up a modem and try auto-confgure as well:
under line aux 0
modem autoconfigure discovery
To actually configure to allow dial in (and this is from memory, it is very rare to see it anymore)
line aux 0
modem InOut
modem autoconfigure type
transport input all
stopbits 1
speed 115200
Keep in mind the modem settings can differ from country to country. As to the cable, there used to be one with every device, DB25 to RJ45 … wit hlike 9 ofd the 25 pins actually hot.
Good luck!

The AUX port is typically used for dial back-up from a remote location. If the router’s primary network interface goes down you can still access the router to troubleshoot from a remote connection by dialing into the phone number associated with the modem.
The type of modem required is simply any dial modem that supports the 9600-8-none-one talk standard that the cisco router uses for communication by default.

you don’t need a Modem, you can connect directly to either console port or AUX port via console cable, the difference will be that for the AUX port you will not see the boot up messages.
however you can connect any standard modem, and you need a console cable, like this one http://itknowledgeexchange.techtarget.co…
