Extending Cisco End-to-End Solutions
As part of the comprehensive Cisco end-to-end networking solution, the Cisco 1700 Series routers enable businesses
to extend a cost-effective, seamless network infrastructure to the small branch office. The Cisco 1700 Family of
access routers includes the Cisco 1751 Router and Cisco 1721 Router—a modular device optimized for data-only
connections. WAN cards work with both devices, as well as with Cisco 1600, 2600, and 3600 Series routers. They
are powered by Cisco IOS Software for robust WAN service between branches and central offices in organizations
with multiple sites. Both feature RISC-based processors to provide performance for encryption and support for
emerging broadband technologies.
The Cisco 1751 Router also shares VoIP technology and analog voice interface cards with Cisco 2600 and 3600
Series routers. This feature provides an end-to-end solution for multiservices communications between offices,
simplifying inventory needs and leveraging IT expertise across more devices in an organization.
