Cisco 1600 Series
The Cisco 1600 series routers connect
small offices with Ethernet LANs to the public Internet, and to a
company's internal intranet or corporate LAN through several WAN
connections such as ISDN, asynchronous serial, and synchronous
serial. All Cisco 1600 series models include one or two Ethernet
ports, and one WAN interface card expansion slot for additional
connectivity and flexibility.

Cisco 2600 Series
The Cisco 2600 series is a family of
modular access routers that offer network managers and service
providers an attractively priced remote branch office solution,
providing the versatility needed to adapt to changes in network
technology as new services and applications become available. With
full support of the Cisco IOS software, the Cisco 2600 series
modular architecture provides the power to support the advanced
Quality of Service (QoS), security, and network-integration features
that are required in today's evolving enterprise and service
provider networks.
It is important to choose the router
that supports the WAN protocols and interfaces you will use. For
example, the 1600 series router and the respective WAN interface
card is an example of a branch office router that will support the
interfaces required in the network topology illustrated in the “Network
Overview” section.
