Cisco 1750 Modular Access Router

Intranets and the Internet have become fundamental strategic resources for businesses, enabling applications that reduce operational costs, increase collaboration, and raise productivity. The future will continue to bring rapid advancements in networking applications and technologies. Companies that prepare for this new world of networking as they implement access solutions today stand to gain a significant competitive advantage.

Preparing a small or medium-size business or an enterprise small branch office for the future means implementing network equipment with three key criteria:

• Flexibility to adapt to changing requirements

• Investment protection with features and performance to support new WAN services such as multiservice voice/data integration, virtual private networks (VPNs), and broadband access today or in the future

• Integration of multiple network functions, including an optional firewall and data service unit/channel service unit (DSU/CSU) to simplify deployment and management

The Cisco 1750 access router delivers these capabilities with the power of Cisco IOS^® software in a modular integrated access solution. The Cisco 1750 provides a cost-effective solution to support applications, including:

• Secure Internet, intranet, and extranet access with optional firewall

• Multiservice voice/fax/data integration

• VPN access

The Cisco 1750 features a modular architecture that enables users to cost-effectively upgrade or add WAN and voice interfaces to accommodate changing requirements and growth. Integrated network services and functions, including an optional firewall, CSU/DSU, and VPN features, reduce the complexity of deploying and managing branch office solutions. Most important, the Cisco 1750 offers investment protection with a RISC architecture and features to support new technologies and applications, including voice/fax/data integration and VPNs, when users are ready to deploy them.

The Cisco 1750 is available in three models that enable users to easily tailor an access solution to suit their branch office requirements today and in the future:

• Cisco 1750---The most basic model available, this unit provides everything a small branch office needs for data networking now, with a simple upgrade path to support integrated voice/fax/data applications when needed. A convenient voice upgrade kit is available to provide voice/fax/data support as needed.

Key Benefits

The Cisco 1700 series supports the value of end-to-end Cisco network solutions with the following benefits:

• Flexibility---The modular Cisco 1750 adapts easily to fit the needs of businesses. Interchangeable WAN interface cards enable easy additions or changes in WAN technologies without requiring a forklift upgrade of the entire platform. Modular data and voice slots enable users to tailor data and voice services as needed. With the ability to use the same field-upgradable WAN and voice interface cards across multiple Cisco access router platforms, the Cisco 1750 reduces requirements for spare parts inventory and support training. In addition, the autosensing 10/100BaseT Fast Ethernet port enables easy migration to high-speed local networks.

• Multiservice Access---For businesses that have data networking needs today and want to integrate multiservice data/voice/video/fax capabilities now or in the future, the Cisco 1750 offers a flexible, cost-effective answer. The Cisco 1750 enables network managers to save on long-distance interoffice billing costs and interoperates with next-generation voice-enabled applications such as integrated messaging and Web-based call centers. The Cisco 1750 works with the existing telephone infrastructure---phones, fax machines, key telephone systems (KTS) units, and PBX---minimizing capital costs.

• Lower Cost of Ownership---The Cisco 1750 router provides a complete solution for integrated voice and data access in a single product, eliminating the need to install and maintain a large number of separate devices. You can combine optional functions, including a voice gateway, dynamic firewall, VPN tunnel server, DSU/CSU, ISDN network termination-1 (NT1) device, and more to reduce deployment and management costs. This solution can be managed remotely using network management applications such as CiscoWorks and CiscoView or any SNMP-based management tool.

• Investment Protection---The Cisco 1750 RISC architecture, Cisco IOS software, and modular slots provide solid investment protection to companies that want a platform that offers data connectivity today and an easy migration path to implement services such as multiservice data/voice/video integration, VPNs, and broadband communications in the near future. A slot on the 1700 series motherboard offers the ability to support future hardware-assisted data encryption at T1/E1 speeds.

Cisco IOS Technology

Internet and Intranet Access

Cisco IOS software provides an extensive set of features that make the Cisco 1750 router ideal for flexible, high-performance communications across both intranets and the Internet:

• Multiprotocol routing (IP, IPX, and 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

• WAN optimization---including dial-on-demand routing (DDR), bandwidth-on-demand (BOD) and OSPF-on-demand circuit, Snapshot routing, compression, filtering, and spoofing to reduce WAN costs

Security

Cisco IOS software supports an extensive set of basic and advanced network security features, including access control lists (ACLs), user authentication, authorization, and accounting (such as PAP/CHAP, TACACS+, and RADIUS), and data encryption. To increase security, the integrated Cisco IOS Firewall Feature Set protects internal LANs from attacks with context-based access control (CBAC), while IPSec tunneling with data encryption standard (DES) and triple DES encryption provide standards-based data privacy, integrity, and authenticity as data travels through a public network.

For remote access VPNs, Layer 2 Forwarding (L2F) and Layer 2 Tunneling Protocol (L2TP) combine with IPSec encryption to provide a secure multiprotocol solution (for IP, IPX, and AppleTalk traffic, and more). Mobile users can dial in to a service provider's local point of presence (POP) and data is "tunneled" (or encapsulated inside a second protocol such as IPSec or L2TP) back to the Cisco 1750 router to securely access the corporate network via the Internet.

Cisco IOS Software QoS Features

Through Cisco IOS software, the Cisco 1750 router delivers quality of service (QoS) capabilities, including Resource ReSerVation Protocol (RSVP), Weighted Fair Queuing (WFQ), Committed Access Rate (CAR), and IP Precedence. These features enable businesses to prioritize traffic on their networks by user, application, traffic type, and other parameters, to ensure that business-critical data and delay-sensitive voice receive the priority they need as they move across the network.

Because the Cisco 1750 router provides robust voice compression, up to sixvoice calls can occupy a single 64K data channel simultaneously, without compromising data performance. The Cisco IOS voice compression technology integrates data and voice traffic to enable efficient use of existing data networks.

High-Performance Architecture for VPNs and Broadband Service

A RISC architecture and Cisco IOS features give the Cisco 1750 the power to support VPN applications with tunneling and security, as well as digital subscriber line (DSL) and other broadband access technologies. A slot on the Cisco 1750 motherboard supports an optional hardware encryption card to provide IPSec DES and triple DES encryption at T1/E1 speeds. The Cisco 1750 with the Cisco 633 router provides SDSL service today.

Ease of Installation and Management

Cisco ConfigMaker, a wizard-based software setup tool, makes it easy to configure Cisco 1750 routers and other Cisco devices from a Windows-based PC. And CiscoWorks2000 provides central monitoring and troubleshooting of remote Cisco 1750 routers, saving time and preventing costly IT trips to branch offices.

The Cisco 1750 router supports a range of network management and ease-of-installation tools:

• Cisco ConfigMaker is a Windows wizard-based tool designed to configure a small network of Cisco routers, switches, hubs, and other network devices from a single PC. This tool makes it simple to configure value-add security features such as the Cisco IOS Firewall Feature Set, IPSec encryption, and network address translation (NAT); establish VPN policies (including QoS and security); and configure the Dynamic Host Configuration Protocol (DHCP) server.

• CiscoView, a GUI-based device management software application for UNIX platforms, provides dynamic status, statistics, and comprehensive configuration information.

• CiscoWorks2000, the industry-leading Web-based network management suite from Cisco, simplifies tasks such as network inventory management and device change, rapid software image deployment, and troubleshooting.

• For service providers, Cisco Service Management (CSM) provides an extensive suite of service management solutions to enable planning, provisioning, monitoring, and billing.

Extending Cisco End-to-End Solutions

As part of the comprehensive Cisco end-to-end networking solution, the Cisco 1700 series enables businesses to extend a cost-effective, seamless network infrastructure to the small branch office. The Cisco 1700 family of access routers includes the Cisco 1750 and the Cisco 1720---a modular device optimized for data-only connections. All WAN cards work with both devices, as well as with Cisco 1600, 2600, and 3600 series routers. Both are powered by Cisco IOS software for robust WAN service between branches and central offices in organizations with multiple sites, and both feature RISC-based processors to provide performance for encryption and support for emerging broadband technologies.

The Cisco 1750 also shares voice-over-IP technology and analog voice interface cards with Cisco 2600 and 3600 series routers. This feature provides an end-to-end solution for multiservices communications between offices, simplifying inventory needs and leveraging IT expertise across more devices in the organization.
