CISCO 800 FEATURES AND BENEFITS
The Cisco 801 model provides an ISDN Basic Rate Interface
(BRI) ST interface for use worldwide. The Cisco 802 adds
the integrated NT1 network termination device for use in
North America. The Cisco 803 and 804 models add a four
port Ethernet hub and two RJ-11 interfaces for telephone
devices such as telephones, fax machines, and modems. The
Cisco 805 offers one serial port for synchronous serial
connections or asynchronous dial up connections with an
external modem.
The Cisco 803 and 804 models also support supplementary
telephone services such as call waiting, call-waiting
cancel, call hold, call retrieve, three-way conferencing,
and call transfer (if these services are supported by a
users telephone company). For North American users, the
Cisco 804 supports caller ID out the POTS port. Field
upgradeable Flash and DRAM memory in all Cisco 800 Series
models protect equipment investments as technologies and
networking requirements change.

Support for WAN Technologies
The Cisco Series 801 through 804 support ISDN switched,
leased line connections, Always on Dynamic ISDN (AODI),
X.25 over ISDN D channel, Bandwidth Allocation Control
Protocol (BACP), Multilink Point-to-Point Protocol
(ML-PPP), Compression Control Protocol (CCP) compression
(up to 4:1), and Bandwidth on Demand (BOD) with load
balancing for links up to 128 kbps, for effective
throughput up to 512 kbps.
The Cisco Series 805 supports both synchronous serial
connections and asynchronous dial connections,
synchronous connections include Frame Relay, leased line,
X.25 up to speeds of up to 512 kbps. When using
asynchronous dialup with an external modem, the Cisco 805
only connects to the Internet when required, and then
immediately disconnects when the line is no longer being
used, minimizing per-minute usage charges. Access control
lists make sure that only important traffic initiates the
Internet connection, further increasing the cost savings.
The advanced routing protocols of the Cisco 805,
including Snapshot and triggered RIP, ensure routing
table information is exchanged efficiently; and STAC
compression increases total throughput. Asynchronous
serial speeds up to 115.2 kbps.
To leverage the unprecedented opportunities offered by
communications and commerce over the Internet, private
information must remain secure. Cisco Secure Integrated
Software provides many technologies to build a custom
security solution. The elements of security services
include perimeter security, identity, monitoring,
privacy, firewalls, IPSec encryption, and VPNs.
Perimeter security refers to the control of traffic
entry and exit between network boundaries, such as
between private networks, intranets, extranets, or
the Internet. Cisco IOS perimeter security
technologies provide a highly flexible, superior
solution with features such as:
Standard and extended ACLs
Lock and Key (dynamic ACLs)
Router/route authentication, authorization, and
accounting (such as Password Authentication Protocol
[PAP]/Challenge Handshake Authentication
Protocol[CHAP]
Network Address Translation (NAT)
Token Card authentication with Cisco Secure
authentication
NAT eliminates the need to re-address all hosts with
existing private network address and hides internal
address from public view. For businesses that want to
allow selected access to the network, NAT can be
configured to allow only certain types of data
requests such as Web browsing, e-mail, or file
transfers.
Dynamic Firewall - Companies increasingly rely on
internal networks and servers for accessing company
data. To leverage the Internet as a key business
tool, companies must connect their internal networks
to the Internet while keeping sensitive internal data
secure. Company data can be protected against
unauthorized access with stateful firewalls. The
integrated Cisco IOS Firewall et,
Stateful (dynamic) ACLs (application/context based)
Java blocking
Denial of service attack detection and prevention
Real-time alerts and audit trails
Dynamic firewalls provide these vital enhanced
security features. The term firewall is used by many
vendors but not uniformly referred to as stateful
firewalls. Firewalls that are not dynamic do not
provide these enhanced security features.
