A Flexible, Easy-to-Manage Router to Secure Your Small Business
More than ever, you need to secure your network to keep you business assets
safe from threats. You depend on your network to keep you connected to the
people you do business with every day, from customers to suppliers and business
partners. Yet when you have a small networking staff, it can be difficult to
manage your network and make sure it is well protected from security breaches.
To be successful, you need a complete network solution that delivers the
security and rich features you need, yet is affordable and easy to use.
The Cisco® 520 Secure Router combines Internet access, advanced security,
virtual private network (VPN) access, and optional wireless networking, all in a
single easy-to-use device. Designed for seamless integration with the Cisco
Smart Business Communications System - a complete set of advanced voice, data,
security, and wireless networking products designed specifically for small
businesses - the Cisco 520 Secure Router brings together multiple technologies
to help you improve network security and simplify network management.

DSL specifications ● ST-Microelectronics 20190 chipset
● Supports ADSL over basic telephone service with Annex A and Annex B ITU
G.992.1 (ADSL), G.992.3 (ADSL2), and G.992.5 (ADSL2+)
● G.994.1 ITU G.hs
● Complies with T1.413 ANSI ADSL DMT issue 2
● DSL Forum TR-067
● The chipset does not provide interoperability with carrierless amplitude
modulation/phase modulation (CAP)-basedADSL lines
● Annex A and Annex B are supported starting with Cisco IOS Software Release
12.4(4)T
● 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.
● The ADSL2+ standard (ITU G.992.5) doubles the bandwidth used for downstream
data transmission, effectively doubling the maximum downstream data rates and
achieving downstream data rates of up to 24 Mbps and upstream data rates of up
to 1.5 Mbps.
Maximum transmit power Note: Maximum power setting is subject to change by
channel and by region, depending on regulations.
