The 4300T Converged Network Appliance
The EdgeMarc 4300T is an intelligent, all-in-one networking solution for enterprises
and service providers. It reduces costs by simplifying the deployment, management
and security of converged voice, video and data networks. The 4300T provides the
following important functions for converged networks:
T1 Wide Area Network (WAN) Access Router
The 4300T provides an integrated T1 CSU/DSU for small and medium office
connectivity.
Security
A stateful packet inspection firewall is used in combination with a VoIP application
layer gateway to provide comprehensive “media-aware” security. The 4300T also
supports IPSec for secure site-to-site networking.
VoIP
The 4300T resolves NAT/FW traversal problems for SIP, MGCP and H.323 traffic. It
allows a single public IP address to be used for multiple VoIP clients. VoIP
survivability is also provided by the 4300T so that local SIP PSTN gateways can be
used for inbound/outbound calling during WAN link failures.
Quality of Service
The 4300T maximizes WAN link utilization while optimizing voice quality using
prioritization and shaping.
Call Quality Monitoring
Passive call quality monitoring for each VoIP call includes statistics needed to enforce
SLAs and resolve networking problems that negatively affect call quality.
Future-proof Scalability
The 4300T is a powerful, flexible platform that can be deployed initially as a low-cost
WAN access router and then licensed through software for more advanced VoIP
features and increased call performance. It is the ideal platform for service providers
offering DIA, hosted VoIP and managed security services or enterprises migrating to
converged voice and data networks.
