The beginning

Communications Systems

• We use here the router 2811, because it has more features.
• For the connection between the different divices I use a Fast Ethernet Connection.
• Between the routers there is a DCE Connection.

Steps:

1. Click at the router and turn it off, than you must put the WIC-1T in the Slot.
2. Switch the router on and repeat the steps with the different router.
3.  Go to connections and select the DCE Serial wire.
4. Click on the router and choose the serial Interface.
