The Cisco AS2511-RJ access server enables users to connect asynchronous devices such as dumb terminals, modems, router consoles, slot machines, and Integrated Services Digital Network (ISDN) terminal adapters (TAs) into a routed network. New features make this product easier to use than ever. Running the same Cisco IOS software that runs the backbone of the Internet on a high-performance router engine, this product also gives users integrated synchronous serial ports to backhaul routed traffic through high-speed T1/E1 lines.
