Cisco AS5200 Series

The award-winning Cisco AS5200 family of universal access servers provide superior density and price/performance for dial pools. Utilizing the differentiated services delivered through Cisco IOS® software, customers have best-of-breed scalability and investment protection. All of these servers include support of worldwide protocols such as V.110, Channelized E1 (R2), and Channelized T1 robbed-bit signalling (RBS).

Universal Access
The AS5200 family is designed to maximize customers' investment protection by terminating both analog modem and ISDN calls on the same chassis from the same bearer line. The AS5200 establishes the entry and midrange of the access server family. Modem ISDN Channel Aggregation (MICA)® technology results in investment protection through modem modules that can be transferred to higher-density AS5200 servers as capacity needs increase.

Applications Service Provider Point of Presence
Frequently, geographic concerns require a service provider to employ a large number of small points of presence (POPs) that are geographically dispersed.

The AS5200, with its compact, cost-effective, medium-density two-Primary Rate Interface (PRI) design is optimal for implementing such a dispersed dial infrastructure. Its redundant, high-speed serial ports provide for backhaul of data to points of aggregation.

High-Density Dial Access
In higher-density implementations, the AS5200 functions as a component of the Cisco Dial Access Stacking architecture (DASA), scaling to provide an access point to thousands of ports. Through the use of Multichassis Multilink Point-to-Point Protocol (MMP) enabled by Layer 2 Forwarding Technology (L2F), Layer 2 Tunneling Protocol (L2TP) and Cisco developed Stack Group Bidding Protocol (SGBP), Cisco's high-density access solutions can grow to meet the requirements of the frequently changing dial environments. Since the initial building block is a relatively small investment, providers can scale from very small to very large installations.
