I am preparing a project for access server. The idea is to have one device to receive ISDN users (BRI), Analog dial modem, and a T1 data link for VPN connection. What device is a good one to use? Is there any configuration sample?
Your options could be anything from a 2600 to 3700 to 5350 to 5850; the differences depend mostly on scaling (number of modems, number of connections, etc).
