Cisco SOHO 78 G.SHDSL Router

Affordable Multiuser Access with the Power

of Cisco IOS® Manageability and Reliability

The Cisco SOHO 78 Router provides an affordable, secure, multiuser DSL access solution to small-office/home-office (SOHO) customers while reducing deployment and operational costs for service providers. Through the power of Cisco IOS^® technology, the Cisco SOHO 78 G.SHDSL Router provides superior manageability and reliability.

SOHO customers need affordable, multiuser access on a single DSL line as well firewall security and reliability. (See Figure 1.) Services providers need to deploy and manage intelligent customer premise equipment that supports SOHO customers' needs while keeping operational costs low. Easy set up, management, and support are key features that help reduce operational costs.

G.SHDSL is the latest version of DSL technology, and it provides business customers a symmetrical service for bandwidth-intensive applications. G.SHDSL can support speeds both upstream and downstream of up to 2.3 Mbps and can reach customers as far as 20,000 feet from the telco/PTT office.

Cisco SOHO 78 Router Benefits SOHO Users and Service Providers

The Cisco SOHO 78 Router provides key features for SOHO users who have more requirements than a DSL modem can provide. Service providers can use the Cisco SOHO 78 Router to offer a DSL service with features beyond simple consumer needs. Additionally, with the Cisco SOHO 78 Router and Cisco IOS Software, service providers can help reduce their operational expenses in providing DSL services.

The Cisco SOHO 78 Router is ideal for small offices or home offices and allows users to share a single G.SHDSL line and a single IP address. The Cisco SOHO 78 Router provides:

Affordable, multiuser access
Secure packet filtering firewall
Easy set up and deployment with web-based configuration

Affordable, Multiuser Access with a Single DSL Line

The Cisco SOHO 78 G.SHDSL Router enables service providers to deploy an affordable, multiuser router that is ideal for sites that need fast, reliable access to the Internet. Network Address Translation (NAT) allows multiple users to share one DSL line with a single IP address. NAT eliminates the need to readdress all PCs with private network addresses. Unlike a DSL modem, which allows only a single PC to connect to the Internet at a time, the Cisco SOHO 78 G.SHDSL Router allows multiple PCs to connect to the Internet simultaneously.

The Cisco SOHO 78 Router also provides an integrated four-port Ethernet hub, which makes it ideal for a small office. As many as four PCs or devices can be connected directly to the Cisco SOHO 78 Router without a separate hub.

Internet Security with Packet-Filtering Firewall

With the always-on connection that DSL provides, network security is essential. The Cisco SOHO 78 Router enables service providers to offer a packet-filtering firewall that helps protect users from unauthorized access. Cisco's packet-filtering firewall logs information and provides an audit trail of unauthorized access attempts. Service providers can use this information to track down the source of these security threats. NAT also provides security by allowing users to hide behind a single public IP address, keeping the PCs behind the router concealed from public view.

Easy Setup and Deployment

The Cisco SOHO 78 Router includes a Web-based configuration tool. The Cisco Router Web Setup tool (CRWS) allows users who have no technical experience to set up the router quickly, without knowledge of Cisco IOS Software and without needing to install any additional software on a PC.

Reduced Cost of Operations for Service Providers

Because the Cisco SOHO 78 Router is based on Cisco IOS technology, service providers can leverage their training and investments in Cisco IOS Software to reduce their overall costs of doing business. With these key management and troubleshooting features, service providers can cost-effectively deploy and remotely manage the Cisco SOHO 78 Router with the following advantages:

Cisco IOS manageability, including interactive diagnostics/debugging features
Familiar Cisco IOS command-line interface (CLI)
Proven reliability and industry-leading support
Lower deployment costs

Remote Management with Cisco IOS Technology

The Cisco SOHO 78 Router incorporates the same Cisco IOS technologies used by service providers and enterprises, allowing service providers to use existing knowledge of Cisco IOS Software to reduce training costs when configuring, installing, and deploying Cisco SOHO 78 Routers.

Additionally, Cisco IOS Software provides many debug features that allow a service provider to diagnose network problems remotely. For example, the G.SHDSL loop analysis feature provides information gathered remotely on line quality and data transfer rates, including train speeds for upstream and downstream, bit error rate, margin, and chipset status, as well bits per frequency bin.

The Cisco SOHO 78 Series routers support centralized administration and management via Simple Network Management Protocol (SNMP), Telnet, or local management through the router console port. Additionally, the world-class support offered by the Cisco Technical Assistance Center (TAC) provides unparalleled support services.

Proven Reliability and Support

Because the Cisco SOHO 78 Router is 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, SOHO customers can depend on them day after day, year after year.

Lower Deployment Costs

Additionally, Cisco aids service providers by helping reduce deployment costs. Cisco Configuration Express, a Web-based ordering system and customized in-line manufacturing process, allows service providers to order preconfigured Cisco SOHO 78 Routers and have them shipped directly to the customer site. This reduces costs for warehousing and deploying products.

This, combined with the Cisco Router Web Setup tool, promotes efficient customer self-installation. End users complete the installation simply by bringing up a Web browser and entering a user name and password. By making deployment of services faster, service providers can save on costs while increasing customer satisfaction.
