It enables service providers and resellers to increase service revenue by supporting features for business-class security, integrated toll-quality voice/data, differentiated classes of service, and managed network access. These value-added features, along with the manageability and proven reliability of Cisco IOS technology, provide the mission-critical networking that businesses require.
Cisco 827-4V ADSL Router
The Cisco 827-4V router is a member of the award-winning Cisco 800 series. With the software upgradeable platform of the Cisco 827-4V router is a memeber of the award- winning Cisco 800 series. With the software upgradeable platform of the Cisco 827-4V router, service providers and resellers can increase revenue by offering DSL services today and provide value-added services as customer technology needs grow. (See Figure 1.)
Because the Cisco 827-4V router is based on Cisco IOS technology, service providers and resellers can take advantage of their training and investments in Cisco IOS Software to reduce their overall costs of doing business. With key management and troubleshooting features, service providers and resellers can cost-effectively deploy and manage the Cisco 827-4V router at the business customers' premise, thanks to the following advantages:
The Cisco 827-4V business-class ADSL router is ideal for up to 20 users in a small business or as an enterprise telecommuting solution to provide secure and reliable access to the Internet or corporate offices.
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.
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 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.
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 routerall 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.
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.
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.
The Cisco 827-4V router, which supports VoIP (and voice over ATM VoATM, allows service providers to offer multiple lines of toll-quality voice service with high-speed data access over a single pair of copper wires.
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.
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.
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.
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.
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.
The Cisco 827-4V router includes the Cisco Router Web Set Up tool, a Web-based configuration tool for simplified installation and setup. To configure the product, users simply point a Web browser to the IP address of the router and follow a few simple steps. This allows the Cisco 827-4V router to be readily installed by non-technical personnel or end users. The setup tool allows a user to enable security, such as packet filtering, as well as the Cisco IOS Software Firewall Feature Set.
Additionally, Cisco offers at no additional cost, Cisco Configuration Express for direct purchase partners which allows Cisco to ship pre-configurated routers to end users. Service Providers, System Integrators and Enterprise can utilize Configuration Express to save on the cost of deployment logistics and warehousing of products. Cisco Configuration Express also enables true plug and play deployments of Cisco 827-4V routers without the need for any configuration tools through custom loaded configurations.
Because Cisco 800 series routers are based on the same proven Cisco IOS technology used on 80 percent of the Internet and because Cisco IOS Software is the industry-standard application for mission-critical enterprise networks, small business and enterprise telecommuters can depend on them day after day, year after year.
