I want to use Cisco 3660 for atm aggregation. Like I have two IMA 4 port E1 Port adapter modules, ATM OC3, multimode Port adapter, 1 port and they all comes in the same chassis Cisco 3660. I want to know is it possible with Cisco 3660, Does 3660 support it if the answer is yes then how can I make cross connect between multiple IMA interfaces and OC3 interface in single chassis; and then further I can connect that OC3 interface to upstream OC3 router.
Na, that is not possible with a router.
For true ATM switching you need something like the LS-1010 that is not manufacred anymore. but very easy and cheap to buy used.
Hope this helps, please rate post if it does!
