Cisco ADSL Router

Bob_the_Goon

Good afternoon chaps,

I am trying to find out what equipment I would need to join a home ADSL internet connection to a cisco router. I thought it would be good experience to set something like this up instead of just using a bog standard ADSL modem.

Is this possible?

Many thanks

I have a 1721 connected to a dlink dsl-300t modem running my broadband.

Is there Cisco router with a built in ADSL interface (or a modular interface for lets say a 2600) so the telephone line would go straight into it?

I use a cisco 827 to connect to my adsl connection. Somewhere on this forum is the config i posted agessssss ago it seems. Anyway they are pretty reliable routers and are far cheaper than buying a modular router and adsl wic.

Cisco make SOHO routers with web interface and CLI. We use them on our WAN remote sites and seem to work pretty well

Wow its been a while since I've been on techexams but i figured i'd answer your question first since DSL is one of my specialities ^_^

Well first off if you want to use a 2600 series router your going to need a WIC-1ADSL card + 64/16F and an ios later then 12.2(15)T to support PPPoE Dialup client

If you want to you get away without the wic then you can use a 2611 and still need 64/16 and a IOS later then 12.2(15)T to support PPPoE Dialer client but you'd have to connect your cheep aDSL Modem to port e0/0 in a bridge and have the cisco router preform the PPPoE authentication as well as NAT and any other fuction you'd need such as DHCP or acccess list.... w/e

If you want to go the cheep way then feel free to purchase a Cisco 827 off ebay which is a SOHO router that has a built in aDSL ATM interface, as well as has a web interface for configuration but only has 10Base-T ports.

Also if you do decide to use the 2600 Series routers or later your going to have to know how to configure the aDSL ATM Interface, PPPoE Dialer interface and the NAT all by command line.

I use a Cisco 3620 with NM-2FE2W, WIC-1ADSL & WIC-1AM for my boarder router runs amazingly stable and fast compared to cheep linksys or dlink or w/e home brand routers you can buy off the shelf at your local retail store...

Any who hope this has helped, if you have any questions at all feel free to msg me.

Well thankyou for all of your help. There is some great advice there.

I think I better check my bank account and get looking on ebay!

Thanks again

heres the basic config for the dsl router.. you could put a another router behind the dsl modem and have the modem perform bridging
