I have a Cisco 6015 DSLAM with 6 STUC-8-TCPAM cards and 4 Cisco 828 devices. I would like to communicate between the 4 Cisco 828 through the Cisco 6015, is there any way that I can set that up? I do not have a router with an ATM interface, so I was wondering will I be able to communicate to the other DSL devices through the DSLAM?
