Cisco 1800 Series Routers

Based on 20 years of innovation, Cisco 1800 Series Integrated Services Router is optimized for data-access applications, providing small-to-medium sized businesses and small branch offices with the complete functionality and flexibility to deliver secure Internet and Intranet access.

The integrated services routing architecture of the Cisco 1800 product family builds on the Cisco 1700 Series Multiservice Access Routers by offering more than a fivefold performance increase, dramatically increased performance with high-speed WAN-interface-card (HWIC) slots that support new HWICs such as the 4 port EtherSwitch HWIC. A wide range of connectivity options is provided with AIM, HWIC, and VWIC modularity, as well as investment protection through the support of more than 30 existing 1700 Series WAN interface cards (WIC/VIC/VWIC data mode only).

The Cisco 1841 Integrated Services Router is part of the Cisco 1800 Integrated Services Router Series which complements the Integrated Services Router Portfolio.

The Cisco 1841 Integrated Services Router provides the following support:

• Wire-speed performance for concurrent services at T1/E1 WAN rates
• Enhanced investment protection through increased performance and modularity
• Enhanced investment protection through increased modularity
• Increased density through High-Speed WAN Interface Card Slots (two)
• Support for over 90 existing and new modules
• Support for majority of existing WICs, VWICs, and VICs (data mode only)
• Two Integrated 10/100 Fast Ethernet ports
• Security
  • On-board encryption
  • Support of up to 800 VPN tunnels with the AIM-EPII-PLUS Module
  • Antivirus defense support through Network Admission Control (NAC)
  • Intrusion Prevention as well as stateful Cisco IOS Firewall support and many more essential security features

Security Features on Cisco 1800, 2800 and 3800 Integrated Services Routers

Secure Network Connectivity for Data
Security has become a fundamental building block of any network, and Cisco routers play an important role in embedding security at the customer's access edge. The Cisco IOS Software security feature sets for the Cisco 1841 router that enable the hardware-based encryption on the motherboard provide a robust array of features such as Cisco IOS Firewall, IPS support, IP Security (IPSec) VPNs (Digital Encryption Standard [DES], Triple DES [3DES], and Advanced Encryption Standard [AES]), Dynamic Multipoint VPN (DMVPN), network admissions control (NAC) for antivirus defense, Secure Shell (SSH) Protocol Version 2.0, and Simple Network Management Protocol (SNMP) in one solution set. In addition, the Cisco 1841 router offers bundled network security solutions with a VPN encryption-acceleration module, making it the industry's most robust and adaptable security solution available for small-to-medium-sized businesses and small enterprise branch offices. As Figure 2 demonstrates, the Cisco 1800 Series routers help enable customers to deliver high-performance, concurrent, mission-critical data applications with integrated, end-to-end security.

Integrated Services
The new, high-performance and secure integrated services architecture of the Cisco 1841 router (as shown in Figure 2) helps enable customers to deploy simultaneous services such as secured data communications with traditional IP routing at wire-speed performance. By offering a hardware-based encryption on the motherboard that can be enabled with an optional Cisco IOS Software security image and the flexibility to integrate a wide array of services, modules, and interface cards, the Cisco 1841 router helps enable businesses to incorporate the functions of a standalone secure data solution.

Architecture Features and Benefits
The Cisco 1841 modular architecture has been specifically designed to meet requirements of small-to-medium-sized businesses and small enterprise branch offices as well as service provider-managed applications for concurrent services at wire-speed performance. The Cisco 1841 router, together with other Cisco integrated services routers such as the Cisco 2800 Series, provide the broadest range of secure connectivity options in the industry combined with availability and reliability features. In addition, Cisco IOS Software provides support for a complete suite of transport protocols, quality of service (QoS), and security. Table 1 gives the architecture features and benefits of the Cisco 1841 router.

Modularity Features and Benefits
The Cisco 1841 router provides enhanced modular capabilities while protecting customer investments. The modular architecture has been designed to provide the increased bandwidth and performance required to support concurrent, secure applications. Most existing WICs, multi-flex trunk interface cards (for data only), and Advanced Integration Modules (AIMs) are supported in the Cisco 1841. Table 2 lists the modularity features and benefits of the Cisco 1841 router.

Secure Networking Features and Benefits
The Cisco 1800 Series features a built-in hardware-accelerated encryption on the motherboard that can be enabled with an optional Cisco IOS Software security image. The onboard hardware-based encryption acceleration offloads the encryption processes to provide greater IPSec 3DES and AES throughput. With the integration of optional VPN AIMs, NAC for antivirus defense, and Cisco IOS Software-based firewall and IPS support, Cisco offers the industry's leading robust and adaptable security solution for small to medium-sized businesses and small enterprise branch offices. Table 3 outlines router-integrated security features and benefits.
