Benefits of Cisco 827-4V Business-Class ADSL Router

Business Class Security for Internet and VPN Access

To take advantage of unprecedented opportunities offered by Internet-based communications and commerce, private information must remain secure. Cisco IOS software provides many features to enable network security and the Cisco 827-4V router offers a stateful inspection firewall. It denies or permits WAN traffic based on a session's state, so requests from users behind the firewall can be received, while preventing unauthorized access. It also provides basic security features such as standard and extended access control lists (ACLs); Lock and Key (dynamic ACLs); router and route authentication, generic routing encapsulation (GRE) tunneling; and Network Address Translation. These perimeter security features control traffic entry and exit between private networks, intranets, extranets, and the Internet.

Beyond Firewall security the Cisco 827-4V router also supports optional data encryption for Virtual Private Networks. VPNs allow secure communications over a public infrastructure such as the Internet. While a firewall provides perimeter network security for a given location, VPNs protect data when sent from one site to another, such as a branch office to corporate headquarters. VPNs use data encryption and secure tunnels to protect the integrity of data traveling over these public connections. The Cisco 827-4V router supports IPSec 3DES encryption, which provides the most secure form of data encryption, and prevents hackers from gaining access to corporate information.

To simplify the set up of VPNs at remote locations the Cisco 827-4V router supports Cisco Easy VPN. The Cisco Easy VPN Remote feature allows a Cisco router with a static or dynamic IP address to automatically establish and maintain a VPN tunnel to a Cisco Easy VPN Server or concentrator. This allows the same ease of configuration and ongoing policy management of VPNs that VPN software clients provide. This cost effective solution is ideal for remote offices with little IT support, or large CPE deployments where it is impractical to individually configure multiple devices. For remote offices or teleworkers, the Cisco Easy VPN Remote feature can be configured with the Cisco Router Web Set Up tool (CRWS), a Web-based GUI. This makes VPN configuration as easy as entering a password, increasing productivity and decreasing support costs.

Intranet Toll-Quality Voice

The Cisco 827-4V router, with four voice ports, is an H.323 standards-based voice-over-IP (VoIP) gateway today. The Cisco 827-4V router supports standards-based H.323 with Registration, Admission, and Status (RAS) protocol support, providing gateway-to-gatekeeper functionality. The gatekeeper maps destination phone numbers to IP addresses. (See Figure 2.)

The key advantages of the Cisco 827-4V router intranet toll-quality voice capability include the following:

Support for New World Services

The Cisco 827-4V router enables service providers to offer small business and enterprise telecommuters additional voice services by using their existing copper infrastructures. By taking advantage of DSL high-speed access, service providers can provide integrated, multi-line voice services over a single pair of copper wires. This enables service providers to offer new voice and data services without incurring the cost of a truck roll or expensive product forklift upgrade.

Award-Winning Toll-Quality Voice Technology

The Cisco 827-4V router employs the award-winning toll-quality voice technology used in the Cisco AS5300 VoIP Access Server Gateway.

This award-winning technology is an integral part of Cisco IOS Software and is available on a range of different products, from the service provider trunking gateways to customer premises equipment (CPE) such as the Cisco 827-4V router—all with the same, best-of-breed voice quality.

The Cisco 827-4V router enables multilayer prioritization of traffic, supporting ATM, Point-to-Point Protocol (PPP), and IP functionality. This product supports optimized voice compression at the application level with powerful digital signal processors (DSPs) and a full range of codecs to offer high-quality derived voice lines, thereby minimizing the use of bandwidth.

Standards-Based Voice Technology

The voice functionality of the Cisco 827-4V rouer , which is based on H.323 standards, enables third parties to develop applications to a standard protocol, resulting in an ecosystem of compatible voice applications such as enhanced call control via gatekeepers, service billing, and network management. Such an ecosystem provides a complete solution for rapid deployment of intranet voice services for small business and enterprise teleworkers.

Voice Applications

The Cisco 827-4V router enables service providers and resellers to increase revenue with new voice services, including intranet toll-quality voice, private branch exchange (PBX) extension, and additional phone lines over a single pair of copper wires.

Differentiated Classes of Service

The Cisco 827-4V business-class ADSL router enables service providers to increase revenue by building differentiated service options based on premium, standard, or best-effort service classes.

It employs quality-of-service (QoS) features such as application-aware networking with IP QoS features and traffic management with ATM QoS features. This enables the router to expedite the handling of mission-critical or delay sensitive applications, such as enterprise resource planning (ERP) or videoconferencing while sharing network resources with lower-priority applications such as Web surfing.

Application-Aware Networking with IP QoS

Using low latency queuing (often called LLQ or Priority Queuing Class-Based Weighted Fair Queuing [PQCBWFQ]), the Cisco 827-4V router enables service providers and resellers to guarantee or differentiate bandwidth based on a specific application or a specific user. For example, the order entry department traffic can be given priority over the marketing department traffic. The ability of the Cisco 827-4V router to restrict the bandwidth of certain applications or users allows service providers and resellers to manage traffic on the basis of application or user requirements.

Resource Reservation Protocol (RSVP) provides QoS admission control, resource reservation requests, and feedback to allow end-to-end bandwidth reservation and management.

Traffic Management Using ATM QoS

In addition to IP QoS features, the Cisco 827-4V router provides ATM QoS features that enable service providers to manage their core ATM network infrastructures to deliver scalable, cost-effective services with QoS guarantees to their customers. Per-virtual-circuit traffic shaping and queuing allow further optimization of the existing bandwidth between customers and various services.

Using the following features, service providers can offer true QoS and cater to applications with special requirements:

Managed Network Services with Cisco IOS Software

Service providers can offer small business and enterprise telecommuters managed network or Internet access with the Cisco 827-4V router, providing service level agreement (SLAs) and response time. SLAs can be critical requirement in serving the business market that is accustomed to uninterrupted service with traditional WAN services such as T1 lines or Frame Relay. When deploying business services with multiple Cisco 827-4V routers, service providers can use tools to provision and monitor these services. The Cisco 827-4V rouer supports the SA Agent feature in Cisco IOS Software that enables the monitoring of SLAs all the way to the customer site. Additionally, in deploying VPNs with multiple Cisco 827-4V routers, service providers can use the Cisco VPN Solutions Center software or Cisco AVVID partner software and services to set up and manage VPN and Firewall connections between customer sites.

Reduced Cost of Operations

Cisco IOS Software Manageability

The Cisco 827-4V router incorporates the same Cisco IOS technologies used by service providers and enterprises, allowing service providers and resellers to use existing knowledge of Cisco IOS Software to reduce training costs when configuring, installing, and deploying Cisco 827-4V ADSL routers. Additionally, Cisco IOS Software provides many debug features that allow a service provider to remotely diagnose network problems. The Cisco 827-4V routers support centralized administration and management via Simple Network Management Protocol (SNMP), HTTP, or Telnet, or local management through the router console port. The world-class support offered by the Cisco Technical Assistance Center (TAC) provides unparalleled support services.
