Alcatel-Lucent 7540 WMG
Wireless Media Gateway
The Alcatel-Lucent 7540 Wireless Media Gateway (WMG) forms an integral part of Alcatel-
Lucent's Mobile NGN solution, delivering a dramatically simplified architecture and
seamless evolution to an IP Multimedia Subsystem (IMS). A high density, multi-service
media gateway with voice and data bearer interfaces (TDM, 'P, ATM), the 7540 WMG is
capable of performing any-to-any switching including native TDM-TDM, native Packet-
Packet, and TDM-Packet.
Features
• Purpose-built, high capacity,
multi-fabric media gateway for
mobile service providers
• Innovative gateway technology
with integrated media server.
• Support for multiple interfaces
(ATM/TDM/IP)
• Extensive set of GSM/UMTS UMA
and IMS features, codecs, and
interfaces -- including IPBCP,
DTMF, Conferencing, Tones,
Announcements, TFO and TrFO,
and Voice Quality Enhancements
(VQE)
• Integrated system management
with Alcatel-Lucent's Mobile NGN
5060 Wireless Call Server
Benefits
Modular, distributed architecture
for reduced CAPEX, shortened
time to market, and efficient
rollouts
Integrated features for fewer
network elements and simplified
network management
Seamless migration from 2G to 3G
and IMS
Media optimization and
transcoder-free capabilities to
ensure the highest voice quality
Ease of integration into existing
networks
