CISCO 2500 Series Router & Access Server Hardware View

The Cisco Access Server 2500 series provides a variety of access solutionsincluding low cost routing functionality for data-only applications (no voice support) for small office and remote site environments. With the added value of the optimized Cisco Internetworking Operating System (Cisco IOS) software, the new high-performance features of the Access Server series reinforce Cisco's status as the premier provider of remote access solutions. Cisco's 2500 Series Access Servers incorporate the latest in communications technology. By extending the popular Cisco 2500 access router and adding asynchronous capabilities, this new generation of servers provides robust and fast service.

There are currently two access servers to choose from, 8 or 16 asynchronous ports, each with 1 Ethernet port, for aggregating multiple network elements to provide a single Telnet access point (telemetry application)-or for attaching 8 to 16 external analog or digital modems in environments where T1/E1 digital circuits are not available, but multiple dial-up telephone lines can be leveraged for low cost remote access.
