Figure 2. Deployment Scenarios for the Cisco 520 Secure Router
This solution can help you accomplish the following:
●
Securely connect your small office: The Cisco 520 Secure Router is ideal for securely
connecting your employees with customers, business partners, and suppliers. Built-in
advanced security and encryption lets you do business over the Internet with confidence
and peace of mind. For example, online stores can safely perform transactions with credit
cards and debit cards.
Move beyond your traditional phone system: The Cisco 520 Secure Router works hand
in hand with other Cisco Smart Business Communications System products, such as the
Cisco Unified Communications 500 Series, to transform your business by securely bringing
together all of your communications—phone calls, messaging, data, and wireless
networking—onto a single network. Your employees can be more productive, and you can
save money by managing and paying for just one network.
●
Upgrade your business communications: If your business is already using the Cisco
Smart Business Communications System, you can strengthen security by adding the Cisco
520 Secure Router. Intrusion prevention and Cisco IOS Content Filtering can add to your
peace of mind, and intelligent network QoS lets you prioritize voice and data network traffic
to improve network performance.
●
Safely connect traveling employees or teleworkers: The Cisco 520 Secure Router is
perfect for travelers or teleworkers who need secure VPN access to office applications and
files. QoS features in the Cisco 520 Secure Router help maintain the integrity of voice
communications from home offices.
Features and Benefits
Data Sheet
The Cisco 520 Secure Router provides:
●
Built-in advanced security: The Cisco 520 Secure Router includes advanced security
features to help protect your business, including a firewall that inspects traffic at the
application layer to help protect the network from unauthorized users, an inline intrusion
prevention system that provides deep-packet inspection to effectively prevent a wide range
of network attacks; built-in encryption using Triple Data Encryption Standard (3DES) and
Advanced Encryption Standard (AES) that lets remote employees connect to the network
securely using IPsec VPN, SSL VPN, or DMVPN; and Cisco IOS Content Filtering to add
another layer of defense against malware and phishing attacks.
●
Increased performance to run concurrent services: The Cisco 520 Secure Router
delivers broadband performance while simultaneously running services such as firewall,
intrusion prevention, VPN encryption, and wireless networking. Managing a single, all-inone router is easier and less expensive than managing multiple network devices.
Optional secure wireless networking: All Cisco 500 Series Secure Router models are
available with built-in 802.11b/g wireless access points to enable your employees to access
the network when away from their desks. Encryption and compliance with wireless network
security standards protect your network traffic every step of the way.
●
Built-in managed switch: An integrated 4-port 10/100 managed switch can connect
computers, printers, and servers in your office. One port on the switch can serve as a
network edge (DMZ) to add an additional layer of security to your network. The switch also
supports VLANs to let you securely separate traffic on your office network.
●
Simplified deployment and management: Cisco Configuration Assistant makes it easy to
configure, install, and manage the Cisco 520 Secure Router. It can also generate status
reports, synchronize passwords, and upgrade software across all of your Cisco network
devices, reducing the time your staff devotes to network maintenance. Cisco Configuration
Assistant is available for download free of charge at
●
Quality of service: The Cisco 520 Secure Router features the QoS intelligence you need
http://www.cisco.com/go/configassist.
to prioritize networking traffic and support crisp delivery of rich voice and video applications.
●
Multiple connectivity options: The Cisco 520 Secure Router offers a number of options
for WAN connectivity, including Fast Ethernet, ADSL over basic telephone service, and
ADSL over ISDN, enabling you to connect your offices with the technology that best meets
your needs.
●
Seamleass integration with the Cisco Smart Business Communications System: The
Cisco 520 Secure Router was designed as an integral part of this complete system of
advanced voice, data, security, and wireless networking for small business.

The ADSL2 standard (ITU G.992.3) adds new features and functions targeted at
improving ADSL performance and interoperability. In addition, the standard adds
support for new applications, services, and deployment scenarios. Among the
changes are improvements in data rate and reach performance, rate adaptation,
improved diagnostics, and power enhancements. The conventional ADSL standard
(ITU G.992.1) provides downstream data rates of up to 8 Mbps and upstream data
rates of up to 0.8 Mbps, and ADSL2 provides higher downstream rates of up to 12
Mbps and upstream data rates of up to 1 Mbps.
