Revamp an old network

[jimadmin]

Our company is moving into a new office and I would like to take the oppurtinity to replace some End of life products.

Current enviornment is 5 remote offices connected to one central office via Cisco 1600 routers over dedicated DS1 lines. The central office provides internet connectivity via a Cisco 2600 over a DS1 line.

I would like to replace the 5 1600 routers in the central office with one Cisco router. Is there such a beast that will provide 5 WAN connections and one or two eth connections?

Option 2 is to cancel all 5 dedicated ds1 lines and replace them with cheaper dsl lines, then provide connectivity from the remote offices via VPN tunnels. Not sure what the hardware requirements are for option 2.

Thank you for your help
