Cisco 2500AS — Access Server Series

Product Overview

The Cisco 2500 access server series represents Cisco`s low cost entry into the access server marketplace. Three new products have recently been added to this family: the dial optimized AS2509-RJ and AS2511-RJ, and the temperature hardened Cisco 2509-ET. The Cisco 2500 access server series gives users the ability to connect asynchronous devices such as dumb terminals, modems, router consoles, slot machines, and ISDN TAs into a routed network. This product family contains new features that make them easier to use then ever, and they run the same Cisco IOS software that runs the backbone of the Internet on a high-performance router engine. They also give users integrated synchronous serial ports to backhaul routed traffic through T1/E1 lines.

The Cisco 2500 access server series provide a variety of models designed for small office and remote site environments. Each model is a fixed-configuration router that supports at least two interface types. Each access server comes standard with Flash EPROM technology for simplified software maintenance. For software, the Cisco 2500 access server series offer a wide choice of feature sets, so you can select the appropriate protocol set for your network environment. These feature sets range from IP and bridging-only to a feature set containing the full array of Cisco`s software functionality.
