Cisco SOHO 77 ADSL Router
Affordable Multiuser ADSL Router with the Power of Cisco IOS Manageability
and Reliability
THE CISCO SOHO 77 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 77 ADSL ROUTER PROVIDES SUPERIOR MANAGEABILITY AND
RELIABILITY.
SOHO customers need affordable, multiuser access on a
single asymmetric DSL (ADSL) line as well as 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 77 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
• Secure packet filtering firewall
• Easy set up and deployment with Web-based configuration
Because the Cisco SOHO 77 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 77 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 77 ADSL Router
Affordable, Multiuser Access with a Single DSL Line
The Cisco SOHO 77 ADSL router enables service providers
todeploy anaffordable,multiuser routerthatis idealforsites
that need fast, reliable access to the Internet. Network
Address Translation (NAT) allows multiple users to share
oneDSLlinewith asingleIP address,andNAT eliminatesthe
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 77 ADSL
router, when connected to a simple hub, allows multiple PCs
to connect to the Internet simultaneously.
Internet Security with Packet Filtering Firewall
With DSL's always-on connection network security is
essential. The Cisco SOHO 77 ADSL router enables service
providers to offer a packet filtering firewall that helps protect
users from unauthorized access from hackers using an access
control list (ACL) to allow friendly traffic to pass through
while stopping unwanted traffic at the firewall.
If an intruder attempts to gain access to the network
through the SOHO 77 and is rejected by the ACL, the packet
filtering 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 packet filtering 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 77 includes Web-based installation
software (available CYQ4 2000), easy-to-follow installation
instructions, and color-coded cabling features. This allows
users with no technical experience to quickly install and
activate a Cisco SOHO 77 router.
CiscoConfigurationExpress allowsservice providerstoorder
pre-configured SOHO 77 routers and have them shipped
directlytothecustomersite. Enduserssimply enterusername
and password to complete the installation.
The Power of Cisco IOS Software
Remote Management
The Cisco SOHO 77 incorporates the same Cisco IOS
technologies used by service providers and enterprises,
allowing service providers to use existing knowledge of
CiscoIOSsoftwareto reducetrainingcostswhenconfiguring,
installing, and deploying Cisco SOHO 77 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 77 series supports centralized
administration and management via Simple Network
Management Protocol (SNMP) or 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.
Proven Reliability
Because Cisco SOHO 77 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.
