Cisco 1600 Series and WAN Interface Cards

The Cisco 1600 series routers have become the proven choice for data access for small branch offices and small businesses because they offer a range of features specifically designed for such applications:

• Modular design for wide-area network (WAN) choice and flexibility

• Advanced security, including optional integrated firewall, encryption, and virtual private network (VPN) software

• End-to-end quality of service (QoS) and multimedia support

• Integrated data service unit/channel service unit (DSU/CSU) with up to T1 speed and integrated Network Termination (NT1)

• Low cost of ownership through WAN bandwidth optimization

• Ease of use, deployment, and management

The Cisco 1720 router builds on the success of the Cisco 1600 routers, delivering greater modularity, security, and integration to small offices.

Cisco 1600 Series Router

Cisco 1600 Series Modular Routers

Cisco 1600 series routers connect small offices with Ethernet LANs to WANs through Integrated Services Digital Network (ISDN), asynchronous serial, and synchronous serial connections. The five basic configurations of the Cisco 1600 product family offer the following ports:

• Cisco 1601---one Ethernet, one serial, one WAN interface card slot

• Cisco 1602---one Ethernet, one serial with integrated 56-kbps DSU/CSU, one WAN interface card slot

• Cisco 1603---one Ethernet, one ISDN Basic Rate Interface (BRI) (S/T interface), one WAN interface card slot

• Cisco 1604---one Ethernet, one ISDN BRI with integrated NT1 (U interface), one S-bus port for ISDN phones, one WAN interface card slot

• Cisco 1605---two Ethernet slots, one WAN interface card slot

The serial WAN port on the Cisco 1601 router supports asynchronous serial connections of up to 115.2 kbps and synchronous serial connections---such as Frame Relay, leased lines, Switched 56, Switched Multimegabit Data Service (SMDS), and X.25---of up to 2.048 Mbps. The Cisco 1602 router integrates a 56-kbps four-wire DSU/CSU, and it supports the same synchronous serial connections as the Cisco 1601 router (except SMDS). The ISDN BRI port on the Cisco 1603 router has an S/T interface, while the Cisco 1604 includes an integrated NT1 with a U interface. The Cisco 1605 R router provides a 10BaseT and an AUI port on the first Ethernet interface and a 10BaseT port on the second Ethernet interface.

The New Cisco 1600 R Models

The new Cisco 1600 R routers (1601 R, 1602 R, 1603 R, and 1604 R) are essentially the same as the original models (1601-1604), but they are "run-from-RAM" routers, similar to the Cisco 1605 R model introduced in late 1997. The new Cisco 1600 R models deliver all the features and benefits of the original models, including the same interfaces, the same functionality, the same feature sets, and the same versions of Cisco IOS^® software and have the same physical dimensions.

The new feature is simply the memory architecture. In the run-from-RAM routers, software is stored in Flash memory and executed from RAM. The original Cisco 1601-1604 routers are "run-from-Flash," where software is both stored in and executed from Flash memory.

The Cisco 1600 R models have three key benefits over the original versions: The first is increased performance for memory-intensive applications such as encryption and compression. Second is improved system availability: the Cisco 1600 R routers permit software upgrades over any interface while the router is running. And third is lower cost: because the Cisco 1600 R models store the software in compressed form in Flash memory, less Flash memory is required to run advanced feature sets (such as Cisco 1600 series IOS IP PLUS).

Modularity for Flexibility and Investment Protection

The WAN interface card slot allows customers to change or add WAN interface cards as their 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's more, the ability to use the same WAN interface cards in Cisco 1600, 2600, and 3600 routers reduces requirements for spare parts inventory and protects investments in existing routers.

All Cisco 1600 models support the following WAN interface cards:

• One-port serial (asynchronous and synchronous)

• One-port T1/Fractional T1 DSU/CSU

• One-port 56/64-kbps four-wire DSU/CSU

The Cisco 1601, Cisco 1602 and Cisco 1605 also accept the one-port ISDN BRI cards for dial or leased line with either S/T or U (NT1) interfaces.

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

CBAC provides stateful application-layer security by examining traffic sessions on a per-application basis and allowing return traffic through the firewall. When a session is initiated internally, CBAC writes a temporary, session-specific ACL entry and deletes the ACL entry upon session termination.

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."

See the Cisco IOS Firewall Feature Set data sheet for further details.

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 (available in Q2CY'99)

Cisco IOS Software Features for Small Office Internet/Intranet Access

Cisco 1600 series routers offer small businesses and small branch offices a complete set of internetworking software features. In addition to the features mentions 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 videoconferencing, distance learning, and voice/data integration

• WAN optimization features such as dial-on-demand routing (DDR), bandwidth-on-demand (BOD), and Open Shortest Path First (OSPF)-on-demand circuit, Snapshot routing, compression, filtering, and spoofing to reduce WAN costs

Ease of Use and Deployment

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 tool 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 ConfigMaker is designed to configure a small network of Cisco routers, switches, hubs, and other network devised 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, and optional color-coded cables can be purchased from Cisco. 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) or Telnet or through the console port.

Part of the Cisco Networked Office

The Cisco 1600 series is part of the Cisco Networked Office (CNO) stack, a suite of flexible and integrated products designed to provide complete networking solutions for small businesses and small branch offices. Other compatible products in the CNO stack include the Cisco 1720 router, Cisco 1528 Micro Hub 10/100. Cisco 1538 Micro Hub 10/100, Cisco 1548 Micro Switch 10/100, Cisco IOS Firewall, and Cisco ConfigMaker software.

Technical Specifications

The ISDN BRI leased line S/T card is designed specifically for the Cisco 1603 and 1604 routers. It is intended for users who require a dialup ISDN BRI line (from the Cisco 1603 or 1604 router fixed-WAN port) and an ISDN leased line (from the ISDN BRI leased line card inserted into the Cisco 1603 or 1604 router). This card is automatically configured only in ISDN leased line mode. ISDN leased line is also known as ISDN Digital Subscriber Loop (ISDL).

• Asynchronous serial protocols: Point-to-Point Protocol (PPP), Serial Line Internet Protocol (SLIP)

• Asynchronous interface: EIA/TIA-232

• Synchronous serial WAN services: Frame Relay, X.25, SMDS

• Synchronous serial protocols: PPP, HDLC, LAPB, IBM/SNA

Memory and Software

The original Cisco 1601-1604 routers have a "run-from-Flash" architecture. The new Cisco 1601 R-1605 R routers have a "run-from-RAM" architecture; the "-R" suffix designates run from "RAM." The different memory architectures have different minimum memory requirements and software part numbers as indicated below. The available software feature sets for the Cisco 1600 R models are the same as those for the original Cisco 1600 models, but because the software for the R models is compressed, they require different part numbers and image codes.

Starting with Cisco IOS software Release 12.0, the base feature sets include some features formerly in Plus: Network Address Translation (NAT), Open Shortest Path First (OSPF), Remote Access Dial-In User Service (RADIUS), and Next Hop Resolution Protocol (NHRP). Plus feature sets contain all the features in their corresponding base feature sets as well as an additional value-added features such as Layer 2 Tunneling Protocol (L2TP), Layer 2 Forwarding (L2F), Border Gateway Protocol (BGP), IP Multicast, Frame Relay switched virtual circuit (SVC), Resource Reservation Protocol (RSVP), NetWare Link Services Protocol (NLSP), AppleTalk Simple Multicast Routing Protocol (SMRP), and Network Timing Protocol (NTP).
