[. . . ] · Business-class DSL--Business-class DSL is delivered through the optional asymmetric DSL (ADSL) or symmetrical high-bit rate DSL (G. shdsl) WICs. The Cisco 1700 Series business-class DSL solution combines the cost benefits of DSL service with the advanced routing capability required for business use of the Internet. Through enhanced DSL quality-of-service (QoS) features, performance levels for mission-critical applications and toll-quality voice/data integration are guaranteed. · Traffic management--The Cisco 1721 is based on Cisco IOS Software, the accepted standard for Internet operations.

Page 7 of 12 Hardware VPN Encryption Module All Cisco 1700 models are equipped with an internal expansion slot to support an optional field-installable hardware VPN encryption module. The VPN encryption module offloads encryption processing from the Cisco 1700 Series RISC processor, providing performance up to T1/E1 speeds. The VPN encryption module (MOD1700-VPN) supports a maximum of 100 remote access tunnels. Cisco IOS Software Feature Sets Cisco 1721 routers support a full range of Cisco IOS features, including multiprotocol routing, QoS, VPN, firewall/ IDS, and legacy IBM protocol and applications in use today. The Cisco 1721 router is shipped with the base Cisco IOS feature sets supporting IP routing and standards such as Network Address Translation (NAT), Open Shortest Path First (OSPF), RADIUS, Remote Monitoring (RMON), VLAN routing, basic QoS feature (Weighted Fair Queing), and Next Hop Resolution Protocol [NHRP]). Cisco IOS IP Plus feature sets contain L2TP, L2F, Border Gateway Protocol (BGP), IP multicast, Frame Relay switched virtual circuit (SVC), RSVP, PPP over Ethernet client, NetFlow, the Netware Link Services Protocol (NLSP), Simple Multicast Routing Protocol (SMRP), the Web Cache Control Protocol (WCCP), and the Network Timing Protocol (NTP). In addition, enhanced QoS features are also supported (LLQ, FRTS, RSVP, CEF, WRED, DiffServ, MLPP with LFI). IPSec encryption is offered in special encryption feature sets (Plus IPSec 56 and Plus IPSec 3DES). To build an IP VPN, the recommended feature sets are IP/Firewall Plus IPSec 56 or IP/Firewall Plus IPSec 3DES. For a detailed list of features and memory requirements for a given feature set, see Cisco IOS 1700 Release Notes. Network Management and Installation Tools The Cisco 1721 router supports a range of network-management and ease-of-installation tools. Cisco Security Device Manager (SDM) is an intuitive, easy to use, web-based device management tool embedded within the Cisco IOS access routers. SDM enables resellers and customers to quickly and easily deploy, configure and monitor a Cisco access router without requiring knowledge of Cisco IOS Command Line Interface (CLI). Through smart wizards, SDM can automate best practices for NAT, ACLs, VPN and firewall deployment. Other common LAN, WAN, and routing protocol configurations can also be easily performed through SDM. Network resellers and customers can further fine-tune router configurations for changing business needs and preview the Cisco IOS CLI for each configuration through SDM. CiscoWorks2000, the industry-leading Web-based network management suite, provides the ability to remotely configure, administer, monitor, and troubleshoot the Cisco 1721 router; and increased 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 CiscoWorks2000, is a Web-based tool that graphically provides real-time status of the Cisco 1721 router. It can drill down to display monitoring information on interfaces and provide dynamic status, statistics, and comprehensive configuration information. Cisco Systems, Inc.
