Cisco 2500 Series

The Cisco 2500 series routers provide a variety of models designed for branch office and remote site environments. These routers are typically fixed configuration with at least two of the following interfaces:

  • Ethernet (AUI)
  • 10BaseT Ethernet Hub
  • Token Ring
  • Synchronous Serial
  • Asynchronous Serial
  • ISDN BRI

All Cisco 2500 models include a minimum of 8 MB of Flash memory, except for the mission-specific routers which include 4MB or 8MB of Flash memory depending upon the Cisco IOS software release. Additional Flash memory can be purchased to allow for dual banking or potential future code growth.

There are two types of DRAM memory in the Cisco 2500 series routers: primary and shared(packet). Primary memory is used to store the operating configuration, routing tables, caches, and queues. Shared memory is used to store incoming and outgoing packets.

Mission-specific routers are entry-level routers that are based on standard Cisco 2500 hardware. However, mission-specific routers contain less memory than standard models and run reduced software images designed for CFRAD, LAN FRAD, and ISDN applications. These reduced software images disable unused ports. Mission-specific routers can be upgraded to full standard-model functionality by purchasing additional software and memory.
