Cisco SOHO 77H ADSL Router

Affordable Secure ADSL Router with the Power

of Cisco IOS® Manageability and Reliability

The Cisco SOHO 77H Router provides an affordable, secure, multiuser digital subscriber line (DSL) access solution to small office/home office customers while reducing deployment and operational costs for service providers. Through the power of Cisco IOS^® software technology, the Cisco SOHO 77H ADSL router provides superior manageability and reliability.

SOHO customers need affordable, multiuser access on a single asymmetric DSL (ADSL) line as well as business class firewall security and reliability. Services providers need to deploy and manage intelligent customer premise equipment (CPE) that supports SOHO customer's needs while keeping operational costs low.

The Cisco SOHO 77H router is ideal for small offices or home offices and allows users to share a single DSL line and single IP address, providing:

Affordable, multiuser access with 4 port Ethernet Hub
Business Class Security with Stateful Inspection Firewall
Easy set up and deployment with Web-based configuration

Because the Cisco SOHO 77H router is based on Cisco IOS technology, service providers can leverage their training and investments in Cisco IOS software to reduce overall costs of doing business. With key management and troubleshooting features, service providers can cost-effectively deploy and remotely manage the Cisco SOHO 77H Router with the following advantages:

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

Benefits of Cisco SOHO 77H ADSL Router

Affordable, Multiuser Access with a Single DSL Line

The Cisco SOHO 77H ADSL router enables service providers or businesses 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, and 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 77H ADSL routere allows multiple PCs to connect to the Internet simultaneously. The SOHO 77H router includes an integrated four port Ethernet hub to allow up to four devices to connect directly to the router.

Business Class Security with Stateful Inspection Firewall

With DSL's always-on connection network security is essential. The Cisco SOHO 77H ADSL router enables service providers to offer true business class security with a stateful inspection firewall that helps protect users from unauthorized access from hackers allowing friendly traffic to pass through while stopping unwanted traffic at the firewall. A stateful firewall 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.

If an intruder attempts to gain access to the network through the SOHO 77H Router and is rejected the firewall tracks the user through an audit trail. This audit trail can then help identify an attack in progress and locate an intruder to prevent future attempts. In addition, the firewall uses NAT to hide internal IP addresses from the outside world to further keep the network secure.

Easy Set Up and Deployment

The Cisco SOHO 77H Router includes the Cisco Router Web Set up tool (CRWS), a web based configuration tool that allows users to quickly self-install the router without knowledge of Cisco IOS software. Because CRWS is web based, no additional software needs to be installed on a user's PC. They simply point a browser to the router and follow a few simple sets to quickly get the router up and running.

Cisco Configuration Express allows service providers to order pre-configured SOHO 77H routers and have them shipped directly to the customer site. End users simply enter user name and password to complete the installation.

The Power of Cisco IOS Software

Remote Management

The Cisco SOHO 77H 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 77H ADSL routers.

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

The Cisco SOHO 77H Series routers support centralized administration and management via Simple Network Management Protocol (SNMP), HTTP, Telnet, or local management through the router console port. In addition, the world-class support offered by the Cisco Technical Assistance Center (TAC) provides unparalleled support services.

Managed Network Services with Cisco IOS Software

Service providers can offer small business and enterprise telecommuters managed network or Internet access with the Cisco SOHO 77H Router, providing service level agreement (SLAs) and guaranteed response times. SLAs can be a 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 SOHO 77H Routers, service providers can use tools to provision and monitor these services. The Cisco SOHO 77H Router supports the SA Agent feature in Cisco IOS Software that enables the monitoring of SLAs all the way to the customer site.

Proven Reliability

Because Cisco SOHO 77H ADSL 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 well into the future.

Note Ordinary circuit-switched telephone service can be supported on the same copper pair as ADSL by using micro filters or plain old telephone service (POTS) splitter connected between the line and phones, fax machines, or modems, to provide filtering of the high-frequency ADSL signal to avoid interference between the voice and the ADSL service.
