Cisco 1000 Series Router
The Cisco 1600 series is relatively new and offers a modular construction that enables the WAN
interfaces to be changed by the customer as needed.
The WAN cards in a 1600 series router can be shared with routers from the 2600 and 3600
router series. This enables the maintenance of only a small set of hot-spare boards.
The 1600 uses the trademark IOS and is generally positioned at a branch office site and not at
a RO or SOHO.

Cisco 1600 Series Router
The Cisco 2500 router series is the oldest router platform mentioned so far. A router from this
series is a fixed configuration router that offers a wide range of options for the branch or central
office.
This router series is not modular. If a different port configuration is needed, a new 2500 is
required.
