Used Cisco 2500 access servers are ideally suited for low-density modem dial-in applications at branch and remote offices. With 16 asynchronous connections available for modems to be attached, the Cisco 2500 access server series is a low-cost alternative to higher-priced, integrated modem solutions. Modem solutions of 56K are available for this product line by using digitally terminated modem banks, like the U.S. Robotics MP/8 I-modem product for X2 support, or the Microcom ISPorte for K56Flex support. Ethernet LAN connections are available, and two synchronous serial ports enable customers to use high-speed T1/E1 WAN connections to the Internet or leased-line private networks.
