Avaya X330WAN User’s Guide 5
The Avaya G700 Media Gateway and P330 switch can be stacked together to
provide a comprehensive converged data and VoIP solution.
Small/Medium Business Connectivity Directly to a Service Provider
X330WAN enables SMEs to connect their LAN directly to an ISP, using a P330
switch. This solution provides independence and flexibility to the SMEs for data
flow and other Internet services.
Functional Concepts Overview
Combining resources is an important component for success for today’s businesses.
X330WAN supplies you with combined required access functionality for branch
offices and SMEs. X330WAN includes all functions necessary for branch office and
SME connectivity.
X330WAN is designed to incorporate the following concepts:
•
WAN access
• Routing
• Security
• Convergence
WAN Access
WAN access enables data and VoIP transfer by providing a link for routing packets
between the WAN and Ethernet/LAN interfaces. WAN access enables connecting
branch offices to headquarters, and providing fast access to the Internet and e-mail.
VoIP services are enhanced when X330WAN is combined with the Avaya G700
Media Gateway or to the Avaya DEFINITY
®
Communications Server.
Routing
The X330WAN access router modules provide routing capabilities to a P330 switch.
X330WAN routes packets between the WAN and LAN interfaces in the access
router module. X330WAN provides support for the major routing protocols, as well
as a Layer 3/Layer 4 Policy classifier. The Policy classifier works per Layer 2
interface and per direction, controlling access and QoS (tagging and mapping to
internal queuing mechanism). X330WAN independently controls the traffic flow in
the P330 from the LAN to the WAN. For more information about these features,
refer to Chapter 4: Operational Concepts and Configuration Examples.
