With on-board LAN/WAN connectivity, new high-density service modules, and support for multiple advanced integration modules, the Cisco 3700 Series Multiservice Access Router delivers new levels of service density for branch offices in a compact form factor. When configured with the 16- or 36-port EtherSwitch network module, the Cisco 3700 Series offers a single, integrated platform that combines flexible routing and low-density switching. In addition, it can support internal inline power for the EtherSwitch ports, delivering a single-platform IP telephony and voice gateway solution that facilitates flexible, incremental, and scalable migration to a converged network. These single-platform solutions help lower total cost of ownership by simplifying training, deployment, and management, and modular expansion options help protect current network investment. As a cornerstone of Cisco AVVID (Architecture for Voice, Video and Integrated Data), the Cisco 3700 Series supports rich Cisco IOS Software features such as availability, quality of service, and security to address the resiliency needs of the branch office. The Cisco 3700 Series combines these features with flexible application and services consolidation to offer branch offices a platform optimized for integrating future services.
