Cisco Systems 801 ISDN Router ( CISCO801 ) - ISDN Router

Cisco Systems 801 ISDN Router Features

ISDN Features

The Cisco 800 Series supports ISDN switched, leased-line connections, AO/DI, X.25 over ISDN D channel, Bandwidth Allocation Control Protocol (BACP), Multilink PPP (MLP), Compression Control Protocol (CCP) compression (up to 4:1), and BoD with load balancing for links up to 128 kbps for effective throughput up to 512 kbps. For ISDN cost control, the Cisco 800 Series supports advice of change and dynamic short hold mode. Also new in Cisco Fast Step Release 2.3 is the point-and-click ability to limit connections to one B channel.

Security

To take advantage of 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/Challenge Handshake Authentication Protocol [PAP/CHAP]), Microsoft CHAP (MSCHAP)
Network Address Translation (NAT) (including multi-NAT)
Token card authentication with Cisco Secure authentication

NAT eliminates the need to readdress 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 take advantage of 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 Cisco 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 128- or 56-bit Digital Encryption Standard (DES) or Triple DES (3DES)
Layer 2 Tunneling Protocol (L2TP)
Generic routing encapsulation (GRE)

Manageability

Cisco 800 Series routers support management by a wide range of platforms and applications. Cisco ConfigMaker, Cisco Fast Step Software (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 console port.

Safe Investment

Small offices with limited time, money, and staff need to know their technology investments are safe. Field-expandable dynamic RAM (DRAM) and Flash memory allow small offices to take advantage of new Cisco IOS feature enhancements. And because the Cisco 800 Series incorporates an advanced processor and memory architecture, it can support future applications as customer networking needs expand.

Companies using the Cisco 800 Series routers can take advantage of Cisco industry-leading support options that ensure that the router stays up and running. These support services include the following:

Cisco IOS Software updates in features such as protocol, security, and bandwidth
Full access to Cisco.com for technical assistance and product information
Twenty-four-hour-a-day access to the industry's largest dedicated technical support staff, with the first 90 days included at no charge

Bandwidth Optimization Features

The Cisco 800 Series reduces cost of ownership by providing best-in-class WAN optimization features to reduce networking charges. These features include:

Dynamic advice-of-charge mode and permanent ISDN connections
DDR dialing of the ISDN line only when needed, plus automatic termination of the connection at the end of a user session
MLP for standards-based B-channel aggregation (RFC 1717) and BACP for obtaining BoD
Snapshot routing for IP and Internetwork Packet Exchange (IPX), which prevents the ISDN line from being dialed only to exchange periodic routing updates
Industry-standard STAC data compression for throughput of up to 512 kbps on ISDN models
ACLs by time of day
Frame Relay-over-ISDN leased lines
X.25 D-channel packet data for maximum use of all available bandwidth

The Cisco 800 Series supports ITU-compliant X.25 service over the ISDN D channel. With this feature, a Cisco 800 Series router cost-effectively supports transaction-oriented applications such as POS authorizations. In addition, the Cisco 800 Series X.25 feature includes priority queuing to improve the responsiveness of traffic over this link.

Installation and Configuration Tools

Each Cisco 800 Series router includes Cisco Fast Step Software to simplify setup, monitoring, and troubleshooting. The Cisco Fast Step application leads users through three easy steps to connect to an ISP or 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 (refer to Figure 2). Cisco Fast Step Software also supports automatic detection of the ISDN switch to further simplify the setup process in Cisco Fast Step.

For additional setup ease, the Cisco 800 Series routers have color-coded ports and cables to help users make proper connections. Quick reference guide documentation provides easy-to-follow installation instructions.
