Cisco 1600 series routers connect small offices with Ethernet LANs to the Internet and to company intranets using several wide-area-network (WAN) technologies: Integrated Service Digital Network (ISDN), asynchronous serial, and synchronous serial such as Frame Relay, leased lines, Switched 56, Switched Multimegabit Data Service (SMDS), and X.25.

Cisco 1601: one Ethernet, one serial, one WAN interface card slot.

CISCO 1600 FEATURES AND BENEFITS

The WAN interface card slot allows you to change or add WAN interface cards as requirements grow or change. With this feature, the Cisco 1600 series offers more flexibility and investment protection than any other product in its class. What is more, the ability to use the same WAN interface cards in Cisco 1600, 2600, and 2600 routers reduces the requirements for spare parts inventory and protects investments in existing routers.

DEVICE INTEGRATION

Cisco 1600 routers deliver a complete solution for remote access for small businesses and small branch offices. They provide not only advanced routing capabilities but also the option to integrate DSU/CSU and ISDN network T1 device (NT1), as well as firewall, encryption, and VPN functionality. This integration reduces deployment time and expense because fewer devices and cables need to be installed and configured. An integrated product also saves space and increases reliability because fewer stand alone devices are required to build the solution. The Cisco 1600 routers simplify ongoing support of small branch offices from a central site through remote configuration, monitoring, and troubleshooting of all integrated functions in the router.

ADVANCED SECURITY

To leverage the unprecedented opportunities offered by communications and commerce over the Internet, private information must remain secure. Cisco IOS security services provide many technologies to build a custom security solution. The elements of security services include perimeter security, firewalls, encryption, and VPNs.

PERIMETER SECURITY

Perimeter security refers to the control of traffic entry and exit between network boundaries, such as between private networks, intranets, extranets, or the Internet. Cisco IOS perimeter security technologies provide a highly flexible, superior solution with features such as:

• Standard and extended access control lists (ACLs)
• Lock and Key (dynamic ACLs)
• Router/route authentication, authorization, and accounting (such as PAP/CHAP, TACACS+, and RADIUS)

FIREWALL

The optional Cisco IOS Firewall Feature Set, available on all Cisco 1600 models, provides formidable firewall functionality, including:

• Context-based access control (CBAC)
• Java blocking
• Attack detection and prevention
• Improved logging and alerts

The Cisco 1605 R router - which supports one WAN slot, two Ethernet ports, and the Cisco IOS Firewall Feature Set - makes an ideal integrated and flexible firewall for small offices. This integrated router/firewall effectively segments an internal, secure LAN from a perimeter LAN exposed to an untrusted network (such as the Internet). thus creating a "demilitarized zone"

VIRTUAL PRIVATE NETWORKS (VPNs) AND ENCRYPTION

The Cisco 1600 series routers may be deployed as an entry-level VPN access solution, supporting DES encryption at rates of up to 128 kbps. The Cisco 1720 router is recommended for VPN applications that require greater performance or 3DES or both. Cisco IOS software for the Cisco 1600 series provides a comprehensive set of VPN features including not only perimeter security and firewalls but also the following key technologies:

• IPSec tunneling with data encryption standard (DES)
• Layer 2 Forwarding (L2F) and Layer 2 Tunneling Protocol (L2TP)
• VPN management tools such as support for VPN policy configuration in Cisco ConfigMaker

CISCO OIS SOFTWARE FEATURES FOR SMALL OFFICE DATA ACCESS

Cisco 1600 Series routers offer small businesses and small branch offices a complete set of internetworking software features. In addition to the features mentioned earlier, Cisco IOS software differentiates the Cisco 1600 Series from the competition with:

• Multiprotocol routing (IP, IPX, AppleTalk), IBM/SNA, and transparent bridging over ISDN, asynchronous serial, and synchronous serial such as leased lines, Frame Relay, SMDS, Switched 56, X.25, and X.25 over D
• Network Address Translation (NAT), which eliminates the need to re-address all hosts with existing private network addresses and hides internal addresses from public view
• Easy IP - a combination of NAT, Point-to-Point Protocol/Internet Control Protocol (PPP/IPCP) and Dynamic Host Configuration Protocol (DHCP) server - which enables the router to dynamically negotiate its own IP address and dynamically allocate local IP addresses to the remote LAN hosts, simplifies deployment, and minimizes Internet access costs
• End-To-End QoS features such as Resource Reservation Protocol (RSVP), IP Multicast, WFQ, and AppleTalk Simple Multicast Routing Protocol (SMRP), which support multimedia applications such as desktop video conferencing, distance learning, and voice/data integration
• WAN optimization features such as dial-on-demand routing (DoD), bandwidth-on-demand (BOD), and Open Shortest Path First (OSPF)-on-demand circuit, Snapshot routing, compression, filtering, and spoofing to reduce WAN costs

EASY TO USE

The Cisco 1600 Series includes a variety of easy, user-friendly installation and configuration features such as color coded ports, removable Flash memory PC cards for easy software deployment, the Cisco ConfigMaker configuration tools and the Cisco Fast Step software tool. These features combine to give the lowest total cost of ownership of any small office router.

Each Cisco 1600 Series router includes the Cisco Fast Step easy-to-use Windows 95, 98, and NT 4.0 based software tool that simplifies the setup, monitoring, and troubleshooting of Cisco routers. The Cisco Fast Step setup application leads users through simple, step-by-step, wizards-based procedures to configure Cisco routers connected to an Internet service provider and remote corporate network. Cisco Fast Step software includes the Cisco Fast Step monitor application, which provides users with router LAN and WAN performance statistics, fault alarms, and troubleshooting assistance.

The Cisco ConfigMaker application is appropriate for advanced configuration of the Cisco 1600 Series routers. A Windows 95, 98, and NT 4.0-based software tool, Cisco ConfigMajer is designed to configure a small network of Cisco routers, switches, hubs, and other network devises from a single PC. Cisco ConfigMaker is designed for resellers and network administrators of small and medium-sized businesses who are proficient in LAN and WAN fundamentals and basic network design. Cisco ConfigMaker includes support for the Cisco IOS Firewall Feature Set (which provides integrated enhanced security capabilities), Network Address Translation (NAT), and Cisco Easy IP software.

In addition to easy-to-use software, the hardware for the Cisco 1600 routers is designed to be "plug-and-play" in four notable areas. First, each of the ports on the Cisco 1600 routers and WAN interface cards is color coded. Second, preconfigured software may be loaded into a Flash memory PC card at a central site, and then a user at remote site may deploy the router by simply inserting the Flash card, plugging in cables, and turning on the power. Third, once the router is running, software upgrades and configuration modifications can be downloaded over the WAN from a central site. And finally, the Cisco 1600 Series allows for centralized administration and management via Simple Network Management Protocol (SNMP) ot Telnet or through the console port.
