The Cisco 3700 Series Multiservice Access Routers are a family of modular routers that enable flexible and scalable deployment of new e-business applications for the Full Service branch office. The Cisco 3700 Series routers optimize the branch office with high performance routing, integrated low density switching, Security, Voice, IP telephony, Video and Content Networking in a single integrated solution. This unique integrated design enables enterprise customers to incrementally adapt to evolving business needs by enabling important services delivered by Cisco IOS , such as Quality of Service (QoS), IP Multicast, VPN, Firewall, and Intrusion Detection, with the performance required for tomorrows business challenges. The Cisco 3700 Multiservice Access Routers are based on the same modular concepts as the Cisco 3600 Series but enable dramatically higher levels of performance and service integration for the branch office.The Cisco 3725 and Cisco 3745 provide on-board LAN/WAN connectivity, new high-density service modules (HDSM), and support for multiple Advanced Integration modules (AIMs) to deliver the highest levels of service density for the enterprise branch office today. Improving on the success of the Cisco 3600 Series' modular architecture, these highly integrated platforms deliver a compelling value proposition with by integrating components previously purchased separately, such as two fixed 10/100 LAN ports and additional memory. With the options of two or four network module slots - which can be adjusted to accept the HDSM modules - three WAN Interface Card (WIC) slots, and two on-board AIM slots, the Cisco 3700 offers many flexible options to enable high densities of services. Providing support for the majority of LAN and WAN interfaces available today on the Cisco 3600 Series platforms reinforces Cisco investment protection promise and maximizes the flexibility of these platforms for the future.
