We have 3 or 4 older sites that connect back to our central site using ATM over 2 T1s. This connection is for both voice and data. Equipment is a 3640router and 8510 switch. These are our last sites on ATM, and we'd like to move them away from ATM as soon as we can.\n\nLooking at the Cisco documentation, it looks like we could use 3925s at thecentral site and at each of the remote locations, with VWIC3 cards (we're using VWIC first generation cards now in the 3640s), and use the drop and insert capability to handle voice and data. I had done some setups like thisat a previous job... it's been a couple of years, but hopefully I still got the concept. If I've got this correct, what do we need for the connectionto the phone system?
