The Cisco SOHO 77H ADSL Router

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 userstosharea singleDSL lineand singleIP address, providing:

• Affordable,multiuser accesswith 4port 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 investmentsin Cisco IOSsoftware toreduce overall costs of doing business. With key management and troubleshooting features, serviceproviders cancost-effectively deploy andremotely manage theCisco 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 ADSLrouter enables service providersor businesses todeploy an affordable, multiuser router thatis 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, theCisco SOHO 77HADSL routere allows multiplePCs to connect to the Internet simultaneously.The SOHO 77H router includes anintegrated four portEthernet hub toallow up tofour devices to connect directly to the router.

Packet Filtering Stateful Inspection Firewall (ACLs)

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 NATto 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 providersto use existingknowledge of Cisco IOS softwareto reduce trainingcosts 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 throughthe router consoleport. 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 offersmall business andenterprise telecommuters managed network orInternet access withthe Cisco SOHO 77H Router, providing service level agreement (SLAs) and guaranteed response times. SLAs can be a critical requirementin serving the business market that isaccustomed to uninterrupted service with traditional WAN services suchas T1 linesor Frame Relay. When deploying business serviceswith multiple Cisco SOHO77H 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.
