Standards-Based H.323 Signaling • Allows an ecosystem of third-party vendors to develop applications for a complete
solution
• Allows rapid low-cost deployment of VoIP
Digital Signal Processors (DSPs) and
Voice-Compression Coders/Decoders
(Codecs) G.711, G.729, G.729b, G.723.1, G.726
• Provide hardware-based compressed voiceto fit significantly more voice lines over
a single copper pair without breaking the end-to-end delay budget
Modular Architecture
Multiple WAN Slots • Supports flexible configurations, including WICs that support G.shdsl, ADSL, dial,
ISDN, E1/T1, and Frame Relay
Support for VIC Slots • Offers added flexibility and investment protection
Multiple Platform Support • Supports G.shdsl WIC on Cisco 1720, 1750, and 1751 at FCS
• Reduces cost of maintaining inventory
• Lowers training costs for support personnel
• Protects investments through reuse on various platforms
Security with VPN and Integrated Firewall
IPSec 3DES Hardware-Based Encryption • Enables creation of VPNs by providing industry-standard data privacy, integrity,
and authenticity as data traverses the Internet or a shared public network
• Hardware-based VPN encryption performance at wire speed (T1/E1)
3DES IPSec, Generic Routing Encapsulation
(GRE), Layer 2 Tunneling Protocol (L2TP),
Layer 2 Forwarding (L2F)
• Offers choice of standards-based tunneling methods to create VPNs for IP and
non-IP traffic
• Is fully interoperable with public certificate authorities and IPSec standards-based
products
• Is part of the scalable Cisco end-to-end VPN solution portfolio
Cisco Unity Client Support • Cisco 1700 Series Routers can terminate VPN tunnels initiated by the Unity Client
Cisco IOS Firewall Feature Set • (Cisco Secure Integrated Software) Includes context-based access control for
dynamic firewall filtering, denial-of-service detection and prevention, Java
blocking, and real-time alerts
• Allows internal users to access the Internet with secure, per-application-based,
dynamic access control while preventing unauthorized Internet users from
accessing the internal LAN
Network/Port Address Translation (NAT/PAT) • Hides internal IP addresses from external networks
• Prevents certain denial-of-service attacks from outside networks on internal hosts
• Allows multiple users access via a single IP address
Password/Challenge Handshake
Authentication Protocol (PAP/CHAP),
MS-CHAP, Remote AccessDial-InUserService
(RADIUS), TACACS+
• Supports all leading user identity-verification schemes
Route and Router Authentication • Accepts routing-table updates from only known routers, ensuring that no corrupt
information from unknown sources is received
Internet Key Exchange (IKE), X.509v3 Digital
Certification
• Ensures proper identity and authenticity of devices and data
• Enables scalability to very large IPSec networks through automated key
management
• Offers support for Certificate Enrollment Protocol (CEP) with certification
authorities (CAs) such as Verisign and Entrust
ATM Features
ATM Traffic Unspecified Bit Rate (UBR),
Non-Real Time Variable Bit Rate (VBRnrt),
Real-Time VBR (VBRrt), and Constant Bit Rate
(CBR) with Traffic Shaping
• Ensures CoS guarantees for real-time traffic, with ability to send traffic over the
appropriate virtual circuit to provide ATM-level shaping and ensure that no
head-of-line blocking can happen between circuits of different or equal traffic
classes
