Connect to cisco 1841


This is more of a business unit. It requires a serial port connection and a fair amount of CISCO networking engineering knowledge. It is command only. No GUI interface.

Help me plz


cisco routers make use of an IOS software for configurations.

you have to connect the router to a computer system through an hyper terminal program in order to access the router command interface,there is no way you will be able to configure this router without having cisco configurations knowledge.

the steps could be complex/complecated for a novice.but all the same,

after running the hyper terminal program on your computer to connect the router(start-accessories-communication-hyper terminal) make sure you use cisco serial cable or a cat5e roll over cable.

press the enter key once and type 'enable' then press enter,

configure terminal,to take you to a global configuration mode.

i will advice that you should contact a cisco person in your area for help

Dial-up link for cisco router 1841


It is possible if the IOS on your router supports the necessary dialing features. You'll need to use WIC-1AM analog modem modules (or similar) in each router. A cheaper alternative would be to use standard desktop modems...the serial ports could be connected to the Aux interfaces on the routers.
Good luck...and I hope this is helpful!!
