Cisco 1701 ADSL
Security Access Router

The Cisco 1701 ADSL Security Access Router provides secure and reliable Internet and corporate network connectivity to enterprise small branch offices and small and medium-sized businesses. It offers business-class ADSL over basic telephone service (Plain Old Telephone Service [POTS]) with a redundant WAN link to help ensure high availability of critical business applications. The Cisco 1701 router also supports integrated security services that help ensure protection of the network and secure data traveling over the Internet. Additionally, advanced quality-of-service (QoS) features prioritize mission-critical data traffic.

Optimized for data connections, the Cisco® 1701 router provides high-speed broadband access through ADSL over POTS (ADSLoPOTS) while helping to ensure high-availability networking with an integrated ISDN backup (see Figure 1 for front view and Figure 3 for rear view). This fixed-configuration router helps to enable a seamless network infrastructure for small and medium-sized businesses and enterprise small branch offices.

When deployed at a small or medium-sized business, the Cisco 1701 router provides access to the Internet and other remote offices, while securing and protecting critical data with integrated Cisco IOS® Software security features. Likewise, when deployed in the enterprise small branch office, the Cisco 1701 router helps to enable secure, reliable connections to corporate headquarters or other branch offices, providing employees access to the corporate intranet.

The Cisco 1701 router helps businesses reduce costs by allowing deployment of a single device to provide multiple services (integrated router, firewall, virtual private network [VPN], QoS, and WAN interfaces) typically performed by separate devices. Cisco IOS Software allows this flexibility, providing the industry's most robust, scalable, and feature-rich internetworking software support, using the accepted standard networking software for the Internet and private WANs.

Business-Class DSL

The Cisco 1701 router combines the cost benefits of DSL service with the advanced routing capability required for business use of the Internet. Cisco business-class DSL delivers strong security features, including wire-speed Triple Data Encryption Standard (3DES) VPN (with the optional hardware encryption module), the Cisco Intrusion Detection System (IDS), and stateful inspection firewall to protect the branch network from malicious attacks. Through enhanced DSL QoS features, such as Weighted Random Early Detection (WRED), committed access rate (CAR), and Class-Based Traffic Shaping (CBTS), the Cisco 1701 helps ensure performance levels for mission-critical applications.

High Availability

For reliable access, the ISDN port on the Cisco 1701 router functions as a backup WAN connection should the primary ADSL WAN connection fail (Figure 2). Additionally, the Cisco 1701 router runs Cisco IOS Software, which can automatically detect WAN failures and automatically re-establish connectivity through the ISDN link. Cisco IOS Software has become the industry-proven standard for reliable business access, and allows businesses to avoid losses resulting from interruptions in WAN connectivity.

Integrated Security and Performance for Enterprise-Class VPNs

The Cisco 1701 router delivers standard integrated enterprise-class security services, including IP Security (IPSec) 3DES for VPNs, as well as stateful inspection firewall and Cisco IDS for network protection. Optional hardware-accelerated IPSec encryption is also available to provide wire-speed site-to-site VPNs. These features provide secure connections via the Internet to connect geographically dispersed offices, business partners, and remote users while providing security, traffic prioritization, management, and reliability equal to that of private networks.

More advanced security features supported on the Cisco 1701 router include Cisco Easy VPN Server and Cisco Easy VPN Remote, software that allows simple deployment and management of VPNs. Using the Cisco Easy VPN Server feature with the optional hardware encryption module, the Cisco 1701 router supports VPN server functionality and establishes VPNs initiated by remote workers running VPN client software on PCs. This helps businesses increase productivity by empowering employees to access information and applications at any time. Additionally enterprise small branch offices can use the Cisco Easy VPN Remote feature to configure site-to-site VPNs with security policies pushed from corporate headquarters to the Cisco 1701 routers, reducing IT support costs at the branch.

Advanced QoS

Cisco QoS features help ensure network performance levels and help businesses reduce WAN access costs by classifying applications, giving the most important applications priority use of the WAN line. The Cisco 1701 router comes standard with a complete suite of advanced QoS features such as the Resource Reservation Protocol (RSVP), Weighted Fair Queuing (WFQ), and IP Precedence. Features such as CAR, policy routing, low-latency queuing (LLQ), generic traffic shaping (GTS), Frame Relay traffic shaping (FRTS), and RSVP help allocate WAN bandwidth for improved performance.

Superior Manageability

The Cisco 1701 router offers superior manageability, supporting numerous enterprise-class network management and ease of installation tools, including Cisco Security Device Manager (SDM), CiscoWorks, CiscoView, and CiscoWorks Small Network Management Solution (SNMS).

Cisco SDM is an intuitive, easy to use, Web-based device management tool embedded within Cisco IOS Software access routers. Cisco SDM enables resellers and customers to quickly and easily deploy, configure, and monitor a Cisco access router without requiring knowledge of the Cisco IOS Software command line interface (CLI). Through smart wizards, Cisco SDM can automate best practices for Network Address Translation (NAT), access control lists (ACLs), and VPN and firewall deployment. Other common LAN, WAN, and routing protocol configurations can also be easily performed through Cisco SDM. Network resellers and customers can further fine-tune router configurations for changing business needs, and can preview the Cisco IOS Software CLI for each configuration through Cisco SDM.

CiscoWorks, the industry-leading Web-based network management suite, provides the ability to remotely configure, administer, monitor, and troubleshoot the Cisco 1701 router. It increases visibility into network behavior to quickly identify performance bottlenecks and long-term performance trends. It also provides sophisticated configuration tools to optimize bandwidth and utilization across expensive and critical WAN links in the network.

CiscoView, part of the CiscoWorks software suite, is a Web-based tool that graphically provides real-time status of the Cisco 1701 router and other Cisco devices. It can display monitoring information on interfaces and provide dynamic status, statistics, and comprehensive configuration information.

CiscoWorks SNMS is a comprehensive, Web-based network management solution that provides a powerful set of monitoring, configuration, and management tools to simplify the administration of small to medium-sized business networks and workgroups that contain up to 20 Cisco internetworking products (switches, routers, hubs, and access servers).
