Hello everyone... my manager has tasked me with setting up a cisco 1720 router for our 2 1.5 Mb T1 lines (they are from the same provider). As of right now they are running through an adtran netvanta 3200 for a usable bandwidth of 3 Mb. Unfortunately the equipment is rented and we cannot change anything if we needed to. So i was given the task of setting up another router for the lines. The thing is i have setup switches and firewalls but I do not have much experience with the cisco routers. Can anyone point me to some good tutorials, sample configs, or information on how to properly setup the router. The 1720 has 2 T1 wic cards...

Thanks in advance

Jonathan
