Chapter 2 Processor Cards Feature Summary
Analog Station Interface Cards
•External data security—IPSec tunneling with DES and 3DES encryption provide standards-based data privacy, integrity, and authenticity as data travels through a public network.
•Remote access security—For remote access VPNs, L2F and L2TP combine with IPSec encryption to provide a secure multiprotocol solution (for IP, IPX, and AppleTalk traffic). Mobile users can dial in to a service provider’s local POP. Data is tunneled (or encapsulated inside a second protocol such as IPSec or L2TP) back to the ASI81 to securely access the corporate network via the Internet.
•QoS capabilities—RSVP, WFQ, CAR, and IP precedence enable businesses to prioritize traffic on their networks by user, application, traffic type, and other parameters, to ensure that business-critical data and delay-sensitive voice receive appropriate priority.
•Robust voice compression—Up to six voice calls can occupy a single 64-KB data channel simultaneously, without compromising data performance. Cisco IOS voice-compression technology integrates data and voice traffic to enable efficient use of existing data networks.
•High-performanceRISC architecture—Supports VPN applications with tunneling and security, and DSL, cable, and other broadband access technologies.
