The Cisco 800 series router offers enhanced network security and reliability through the power of Cisco IOS technology tailored for small offices and telecommuters. Cisco 800 series routers extend the power of Cisco IOS technology to small offices and corporate telecommuters. With Integrated Services Digital Network (ISDN), ISDN Digital Subscriber Line (IDSL), and serial models, the Cisco 800 series of routers addresses virtually all WAN services required by small offices and telecommuters. Cisco IOS technology offers enhanced security, reliability, and safe investment with low cost of ownership to enable customers to benefit from the Internet economy by increasing productivity, simplifying communication, and reducing costs. The Cisco 800 series enables customers to benefit from value-added services such as managed network services, virtual private networks (VPNs), point of sale (POS) applications, and secure Internet access.

The Cisco 800 Series includes four ISDN routers, one serial router, and two IDLS router models and a choice of software feature sets. The Cisco 801 model provides an ISDN Basic Rate Interface (BRI) ST interface for use worldwide. The Cisco 802 adds the integrated NT1 network termination device for use in North America. The Cisco 803 and 804 models add a four-port Ethernet hub and two RJ-11 interfaces for telephone devices such as telephones, fax machines, and modems. The Cisco 805 offers one serial port for synchronous serial connections or asynchronous dial up connections with an external modem. For IDSL connections, the Cisco 802 IDSL provides one IDSL port with one Ethernet port and the Cisco 804 IDSL adds an integrated 4-port Ethernet hub.

The Cisco 803 and 804 models also support supplementary telephone services such as call waiting, call-waiting cancel, call hold, call retrieve, three-way conferencing, and call transfer (if these services are supported by a users telephone company). For North American users, the Cisco 804 supports caller ID out the POTS port. Field upgradable Flash and DRAM memory in all Cisco 800 Series models protect equipment investments as technologies and networking requirements change.

Support for WAN Technologies
The Cisco Series 801 through 804 supports ISDN switched, leased line connections, Always on Dynamic ISDN (AODI), X.25 over ISDN D channel, Bandwidth Allocation Control Protocol (BACP), Multilink Point-to-Point Protocol (ML-PPP), Compression Control Protocol (CCP) compression (up to 4:1), and Bandwidth on Demand (BOD) with load balancing for links up to 128 kbps, for effective throughput up to 512 kbps.

The Cisco Series 802 IDSL and 804 IDSL also supports IDSL which offers high-speed digital connections over an ISDN infrastructure and supports line rates up to 144 kbps. IDSL dramatically expands the reach of DSL connectivity for those customers who are outside the Service Provider`s range for DSL or for those who are unable to qualify for DSL connections. IDSL supports VPN connections for telecommuting and branch offices as well as small businesses who need fast, reliable Internet access.

The Cisco 805 supports both synchronous serial connections and asynchronous dial connections, synchronous connections include Frame Relay, leased line, X.25 up to speeds of up to 512 kbps. When using asynchronous dialup with an external modem, the Cisco 805 only connects to the Internet when required, and then immediately disconnects when the line is no longer being used, minimizing per-minute usage charges. Access control lists make sure that only important traffic initiates the Internet connection, further increasing the cost savings. The advanced routing protocols of the Cisco 805, including Snapshot and triggered RIP, ensure routing table information is exchanged efficiently; and STAC compression increases total throughput. Asynchronous serial speeds up to 115.2 kbps.

Integrated CAPI Support for European Markets
The Cisco 801-1RCAPI and Cisco 803-1RCAPI series models are designed to take full advantage of popular European ISDN services. Integrated support for common application programming interface (CAPI) applications provides access to services such as faxing and online banking and a range of leading Internet service providers. Cisco 800 series Internet access devices are available with one-user or five-user RVS-COM Lite licenses, for access to all RVS-COM applications and CAPI applications. And since the CAPI 2.0 driver is built into the Cisco 800 series, there is no need to purchase separate software for your server. CAPI is an application programming interface standard used to access ISDN equipment connected to basic rate interfaces (BRIs) and primary rate interfaces (PRIs). Using a Cisco 800 series with RVS-COM Lite software provides a truly shared network environment and other benefits including: Soft fax (for analog and digital lines) for use with software such as AVMs Fritz!32, Symantec WinFax Pro, and RVS-COM Lite 1.6: Soft modem for e-mail and Web access to Internet service providers such as T-Online and CompuServe File and Euro-File Transfer Electronic banking and shopping with German T-Online Third-party CAPI-compliant applications.

Security

To leverage the unprecedented opportunities offered by communications and commerce over the Internet, private information must remain secure. Cisco Secure Integrated Software provides many technologies to build a custom security solution. The elements of security services include perimeter security, identity, monitoring, privacy, firewalls, IPSec encryption, and VPNs.

Standard 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 ACLs
Lock and Key (dynamic ACLs)
Router/route authentication, authorization, and accounting (such as Password Authentication Protocol [PAP]/Challenge Handshake Authentication Protocol [CHAP])
Network Address Translation (NAT)
Token Card authentication with Cisco Secure authentication
NAT eliminates the need to re-address all hosts with existing private network addresses and hides internal addresses from public view. For businesses that want to allow selected access to the network, NAT can be configured to allow only certain types of data requests such as Web browsing, e-mail, or file transfers.

Enhanced Security

Dynamic Firewall — Companies increasingly rely on internal networks and servers for accessing company data. To leverage the Internet as a key business tool, companies must connect their internal networks to the Internet while keeping sensitive internal data secure. Company data can be protected against unauthorized access with stateful firewalls. The integrated Cisco IOS Firewall Feature Set is a stateful firewall that provides:
Stateful (dynamic) ACLs (application/context based)

Java blocking
Denial of service attack detection and prevention
Real-time alerts and audit trails
Dynamic firewalls provide these vital enhanced security features. The term firewall is used by many vendors but not uniformly referred to as stateful firewalls. Firewalls that are not dynamic do not provide these enhanced security features.

Encryption and Tunneling

The Cisco 800 series routers provide IPSec encryption technology to enable small offices and telecommuters to deploy VPNs. IPSec encryption provides privacy, integrity, and authenticity for transmission of sensitive information over the Internet. The unique end-to-end Cisco offering allows customers to implement IPSec encryption transparently into the network without affecting individual PCs. The 800 series with IPSec encryption allows significant cost savings by using the Internet to create secure connections between small offices and teleworkers. As a component of the Cisco VPN solution, the Cisco 800 series supports:

IPSec tunneling with data encryption standard (DES)
Layer-2 Tunneling Protocol (L2TP)
Generic Routing Encapsulation (GRE)

Manageability

The Cisco 800 Series supports management by a wide range of platforms and applications. Cisco ConfigMaker and Cisco Fast Step (Windows 95, 98, and NT 4.0), and CiscoView (UNIX) applications provide superior capabilities for configuration and security management, as well as performance and fault monitoring. The Cisco 800 Series supports centralized administration and management via Simple Network Management Protocol (SNMP), Telnet, or local management through the router`s console port.

X.25 over the D Channel

The Cisco 800 Series supports International Telecommunications Union (ITU)-compliant X.25 service over the ISDN D channel. With this feature, the Cisco 800 Series cost-effectively supports transaction-oriented applications such as point-of-sale (POS) authorizations. The X.25 feature also allows users to take advantage of unused capacity on the D channel. The always on dynamic ISDN (AODI) technology in Cisco IOS software allows users to minimize call charges by initiating the lower-bandwidth D channel in always-on mode when a user makes an ISDN connection. AODI activates the more costly B channel only when a specific transmission requires more bandwidth. In addition, the Cisco 800 Series X.25 feature includes priority queuing to improve the responsiveness of traffic over this link.

Dynamic Addressing

Workstations on the remote LAN can be assigned IP addresses dynamically by either the central network or the Cisco 800 Series router using the Internet-standard Dynamic Host Configuration Protocol (DHCP). The Cisco 800 Series implements both a DHCP relay agent and a DHCP server, giving network administrators a choice of mechanisms for assigning IP addresses to the routers and workstations.

Easy to Set Up

Each Cisco 800 Series router includes Cisco Fast Step, an 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 Set 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 includes the Cisco Fast Step monitor application which provides users with router LAN and WAN performance statistics, fault alarms, and troubleshooting assistance. The Cisco 800 Series routers also support configuration with the Cisco ConfigMaker application. A Windows 95, 98, and NT 4.0-based software tool, the Cisco ConfigMaker is designed to configure a small network of Cisco routers, switches, hubs, and other network devices 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. The Cisco 800 IDSL models include DSL Connection Kits. The Cisco 800 DSL Connection Kit includes the Cisco Fast Step application with two configuration templates for simplified installation and set up. For additional setup ease, the Cisco 800 Series includes color-coded ports and cables to help users make proper connections. A Quick Product Reference Guide documentation provides easy-to-follow installation instructions.

Virtual Private Network Services for Telecommuters

A virtual private network (VPN) connects private networks and telecommuters by using a public network (such as the Internet), but provides services and capabilities that seem like those offered by dedicated private lines. For VPNs to provide the same benefits as dedicated lines, they must offer similar levels of security and quality to guarantee availability. As implemented in Cisco 800 Series routers, industry standard IPSec encryption offers a complete solution to telecommuters for secure remote access to VPNs, with mission-critical reliability and availability.

All-in-One Solution

The Cisco 803 and 804 models provide an all-in-one solution with a four-port Ethernet hub and two POTS interfaces, which enable users to meet their needs for data, telephone, and fax networking with one device. Now small offices and corporate telecommuters can reduce telephone line charges by combining their data, telephone, and fax communications on a single ISDN line. With one of these Cisco 800 series models, users can simultaneously use the Internet, receive a fax, or make a phone call while reducing the expense of multiple telephone lines.
